Introduction In recent years, the impact of urban sprawl on the costs of transportation services has become -an important t o pic of debate, especially as fiscal budgets have become tighter The prevailing view has been that sprawl is an inefficient urban f orrn and that high-density devel opment i s preferable. This view, however, runs counter' to Amer icas preference fo r densi ty li vin g which is exactly the type of development that continues to occur today. A l though the debate over spraw l and its possible impacts has been going on for a l most 30 years, the issue remains i n its infoncy in terms of sig.nificant and extensive research This is especially true concerning sp r awr s impact on the costs of transportation. The strong and com plex relationship that exists between spraw l and transportation has been reviewed from many differen t perspec tives but the question of how this rela tio nshi p affects t r ansportation costs remains to be answered. This report offers a glimpse of many of the views and theo ries o n sprawl over the past three decades. Much of the literature deals "'ith the costs of spraw l in general without n ecessarily focusi ng on transpor t ation costs In addition, the('e is a paucity of data and analysis on transporta cion costs associ a ted with urban form. The extreme comp l exity of the issue significantly com plica tes i t s analysis. Many factor s enter into any analysis of the costs of spraw l : the initial assump tions, the variables selected to measure costs, the sources of data, the type of analysis, etc T h ough many reports have studied the effects o f spraw l o n transportation, there has yet to be a comprehensive report that accuratel y differentiates the transporta tion costs or increases in costs tha t can be directly a t tribu t e d to low-densi ty devel op ment. The following are reviews of numerous reports addressing urban sprawl published since 1965, with nine of them bei n g identified as the more signifi cant studies (see Tab l e 1). Among them is the 1 97 4 landmark study by the Real Estate Research Corporation (RERC), The Costs a/Sprawl, w h ich r emains one of the most com p r ehensive studies on the subject. The Costs a/Sprawl was t he first extens ive study on the costs o f sprawl and established a benc hmark for future research. Further research has proved t hat the subject is difficu l t to study and has no simp l e answers. The complexity of existing the interrelationship between transportat i on and spraw l and the lack of a definitive descr i ptio n of sprawl are among the many reason s that account for the difficulty in discerning t he costs of sprawl. Numerous theories and studies have emerged that while seeming reasonable and valid by themselves, tend to COJJtra die t each other New travel patterns are being observed, such as the suburb to suburb commu te, as are rising levels of nonwork travel. Mass transi t continues t o be advocated despit e requiring huge subsidies and the debatable success of many recent projects. In fill develo pment and plan ned urban villages have been proposed as solutions to the "problem'" of urban sprawl. In addition to the n i ne more important studies a number of o t her studies are reviewed here, but their coverage i s relatively short because they are not deemed to be especially signiica11t in the argument with resp ect to transportation costs.

The Transportation Costs of Sprawl Pre-1970 In the 1960s, the President's Task Force on Suburban Pwblems reported that sprawl consumes more land than necessary and, with excessive public .costs, frustrates a rationa l transportatio n pohcy. During this time, the conven t ional wisdom on the subject believed that transportation costs would skyrocket if devel opme n t contributed to spraw l. In "The N at ure and Economics of Urban Sprawl," Harvey and C l ark (1965) analyze the costs of urban sprawl. The authors identify four problems in the literature of urban sprawl. First, there are several, sometimes co nflictin g views on the definition of u rban sprawl. I t seems an operational definition has not been found. Sprawl can describe m erely the of the urban periphery or the dispersmg of the urban pop ulace into t he rural lands cape. SecoJld, the many causes of urban sprawl have not been categorized and thus can n o t be discussed as a lrnit. Third, sprawl is i nfrequently viewed as a dynamic phenomeno n Fi nall y, the costs of urban sprawl have not b een quantified. The authors delineate three forms of urban sprawl. Low-density development is seen as the lowest order of sprawl and t s the least offe n s ive. Ribbo n development is seen as the second form of urban sprawl. This sprawl is composed of "segments compact with in themselves but which exte.o d axially and leave the interstices undeveloped." A third type of spraw l is l eapfrog development, which is the settlement of noncompact urban areas It is this type of sprawl that is often attacked and is the form of development t hat incurs the g r eatest cost in providi.tg services to outlying areas. Transportao.on is seat as a catalyst t o urban sprawl. T h e automobi l e i s the primary mode of t ransportation tha t permits access to remote areas and allows sprawl to contin ue. The conclusion o f this rticle is tha t "sprawl occurs in fact, because i t is. economical in terms of the altemattves available to the occupants." Ha rvey and Clark do not show the aetna! transporta t ion costs of urban sprawl, but believe that these costs should not rise significant ly in sprawl l ike areas. In 1967, Kain pointed out in Urban Form and the Costs of Urban Services" t hat the prevailing belief 011 urban sprawl is complica t ed by idealogy and the vari ous definitions of sprawl.lt was concluded that there is a weak dependen cy on the costs of urban services and land use pat terns. When urban service costs are measured, any savings in the develop ment of high densi t y areas are often negated by increasing cost of construe: tion. He indicates tha t "the constderatton of excess capacity of existing public services in specific development situations has confused th e relatio nship between residential density and costs of urban services.', 1970s Real Estate Research Corporation's (RERC) 1974 report, The Costs of Sprawl, is considered to be the bench mark study on sprawl. Thi s was the first intensive effort to identify and q u anufy che eco nomic impacts of sprawl. The r ep?rt analyzes six hypothet ical commum ty development forms: htgh-denslty planned development; low density sprawl; low density planned developmen t; mix; planned mix; a n d a combmatton of 50 percent planned mix with 50 percent spra" l mix.

4 Sf AT tl\AHSPORTATIDM POUCY OOTlATIVE made for each community type for a wide variety of cost categories. The report's atalysis of transportation costs focuses on the capital costs a nd operating/ mainte nance costs for the streetS and roads required to serve each community type. Estimates of arterial> collector and minor street length are made for each communi ty type based on numerous community growth and developm ent studies. These estimated lengths are then multip lied by the cost per line! foot of roadway. Recognizing tha t rods in developments wit h higher densities would need to be wider and co ntain more amenities such as sidewalks, ligh t ing, and gutters, t h e report varies the cost per li ne-al foot for eac h category of roadway t o reflect the needs of each development patter n However, t h ese costs are not va ried to reflect any differentiation i n levels of signalizatio n o r overpass bridge structures. Except f or minor roads,. all pavements are assumed to be concrete. T h e report est.imates t hat a low-densi ty community would require more than six times the amomt of minor streets i n a p l anned high-density commu nity This difference in minor street l e ngth required by these two commun it y types accounts for the conclus i on by the report that the transp o rtation costs o f sprawl ore twice as high as those of planned high-densi ty development. N o other economlc costs othe r than those based on r oad lengt h ore considere d for transportauon. Tv.o indirect c o sts of sprawl associated with t ransport a tion arc also considered by the report. Both of these indir ect costs are based on the theory that tr ip l engths in a sprawl -like area are long e r than in compact. urban areas. First t r avel time is found to increase and is categorized as "personal costs" by the report. Second, the report concludes that sprawl g enerates about t wice as much alr pollution as a planned high-density commu n ity The significant d ifference between the air pollution levels was the amou nt generated by automobile travel. The report's assumption that vehicle miles traveled would be t w ice as h igh in a sprav.l commu n ity as i n a planned h igh-density community accounts for this difference. The report's calcul ations of transport tion com appear overly sim plified. Missing from all the these t ransportation costs are any costs associated v.ith alter nate forms of tra nsportation In "Review o f the Costs of Sprawl, Alt shuler (1977) examines the accuracy and applicability of t h e RERC landmark re p ort Results of the report are com p a red to the experiences of actual communities the omission of key cosrs are hi ghlighted, and the validity of th e rep ort's concl usions are q uestioned. T h e author comments that no expenditures for mass transit were included in the RER C report, despite its assumption t hat planned high-density development" would signifi cant l y mi l ize mass tran s i t. Alts h u l er s fir.-c assertio n i s that actua l high-density communities t end to demand more expensive packages of communi ty services and that the re port incorrectly assumes t h at density did not affect the demand level for community services. Next, he identi fies several o missions of key costS from t h e report s calculati ons> one of which is the lack of any mass trans it exp enditures W ith these m issing costs consider e d, t h e validity of the repo rt's r esults are seriously questioned. Altshuler also dlsputes the reduc tion in amo unt o f auto travel for hi gh-densi ty comm unities assumed by the report and shov.rs that i f a more conservative estimate of the red uction i n au t o travel is used, the n the rep ort's stated claim that l ow dens ity sprawl used 44 percent more energy shrinks drastically, to only 14 percent.

even though the a5$umed reduction i n .aut omobile travel was taken into account. The report does state that it is difficu lt to differentiate the transportation costs related to different types of urban form Alts hul er c on cludes that th e report exaggerates the costs of sprawl. F urther more, he concludes that the r eport"s c redibility is weakened by its use of exaggerated figures, the o.rtUssion of key costs, and t h e inadeq uate calibration of assumptions with actual existing conunu nities. He proposes that the report's methodology and analysis be refine d but he believes, however, that this is a l and rnar. k report that would s erve a.s a good starting point for futur e research on u rban form. Despite t h e shortcomings that cast doubt o n the validity o f the report's conclusions the RERC report cannot be underestimated and continues to be a benchmark for future research on the costs of sprawl In The Urbfln TrampoTtation System, Altshule r (197 9 ) exa.rtUnes the American transportatlon sys tem and its related politics and policies. It reviews the problems of th e cur rent automobile dominated transportation system a nd considers future policy innovation. In exa.rtUning the development of the American tran sportatio n system, Altshuler cons i ders several factors. the American public ha.s two st ron g preferences: the automobi le and low density development. Second, on e of the most powerful lobbies in American policies in the 1950s and 1960s wa.s highway interests. T hus, a.s a result of pressure f rom the publi c and industry, sprawl and the do.rtUnance of the Ameri can transportation system by the a utomo bile have both been facilitated by a complex and exten s ive series of govern mcnt actions since World War II. The public is now served by a transportation system that p r ovides excellent mobility at a c ost t hat the pub li c willingly accepts Altshuler reviews the issue of sprawl and presents arguments from both sides of the spraw l debat e He agrees that sprawl may cause some of the problems claimed by its critics, but states, however, that these claims are exaggerated and that it rc.mains unclear whether or not sprawl is more costly than other f orms of development. He also concludes that Americans, with thei r preference for low density development, wiU refuse to live io densities of sufficient magnitude to bring about any n oticeab le changes to the problems associated with sprawl.

They cite a study by Morrison and Abrahamse which i ndica ted t hat the distance to the work place became sh orte r when t h e inhabitants Jived in suburban areas rather than in urban ones and conclude that this finding is relevant t o the debat e of urban sprawl, because m:my of the arguments showing the adverse affect of urban sprawl assumed that a s the ci t y becom e s decentraliz e d the infrastruc ture costs e x plode T h e conven tio nal wisdom on u rban sprawl, seeing i t as cos tly models the environment search Corporation and numerous othe .rs, who contend that growth assumes a mo nocentric model and trip costs increase with d istance from the cent er. ln "Beyond the Journey to Work Gordon eta!.

8 STATB TRAHSPORTAnoN POUCY IHI'ftATTVB Gordon and Richardson (1989) wro t e a counterpoint article to Con sumption in Cities'" by Nev.rman and Kenworthy (NK). The original article compared gasoline consumption in U.S. cities with other i nd ustrlali7..ed areas a rou nd the world and concluded th at the average consumption of gasolin e by Amer icans i.s far greater than t heir glob a l counterpa rts. NK argue that this con sump t i o n ''mainly reflects land use patterns and t he transporta tio n system,"' and t h eir recommendations ore that growth return to a m ore compact form and cities invest in mass transit Gordon and Richardson are proponents of decentra lization of citi es and contend, b ased on their previous researc h tha t ''decentraliza tion reduces pressures on the central business district relieves congestion, and avoids 'grid lock'." They find no relation shi p between city size and trip l engths. With regard to rail t ransit, Los Angeles p lans t o spend $43.7 billion on new transit inve stme nts pl u s $2.96 billion for annual ope rati ons and maintenance, so each work trip would cost approximately $14.75 if the target ridership of 19 p e r cent of total trips co ul d be a ttained. This w o uld not be a n attrac t ive alternat ive to th e private vehicle in t erms o f cost. P ho eni x Arizona, reject ed an $8.5 b i ll i on mass t ransit plan on Mareb 28, 1989, because of the belief t hat it wou l d rtot be cost effective (Bingham, 1989). The argument o n whet h e r this system s h ou ld be i nstalled is still in debate. Urban villages were supposed to be built around the rai l lines, and wheth e r this increases or decreases urban sprawl i s st.ill unclear. In former P resident Carter's Commission for a Natio nal Agenda for the Eight ies, the value of low-density development v.ras reappraised, and spraw l was destigmatized by point i ng to its social and economic adv a n tag es Another curren t development in urban growth i s the idea of (urban villages" that replace sprawl with higher resid ential densities. Audirac et a L (1990) maintai n that these v illages generate their own sprawl and will not reduce cortgestton. There are strong feelings that rail mass transit i s the supe rior form of t rans porta tion. Broosly (1981) exam i ned t h e BART system i n San Francisco. Constructed in an idea l environment to succeed, Brodsly considers t h e BART system a failu re. Enormously e xpensive, the BART system failed to re place the auto m obile as t h e transpor tation cho ice for commutin g Instead, i t has merely complemented c a r travel an d g e n er at e d a multitude of trip s over w hat it had replaced. With its ene rgy costs, Brodsly states th at th e system will take many decades to repay its costs. The heavy subsidies necessary for rapid transit to exist are a testament to the mode,s e xp ense. As an a lternative to the costly heavy rail system s light rail tran sit S}'stems are b e ing promo ted. This systern's costs are closer t o t hose o f a bus system, yet offer many of the more attractive features o f heavy raiL However, a study looking at the i n itia l experiences of new l ight rail s y>"tems in San Diego Calgary and Edmont.on indicates that these systems may not be the an sv.er. Ea c h city exper-i enced small gains in ridership (over bus systems) and significant cost increases. In San Diego for instance, t h e cost per passenger on the light rail was $3 versus $1 f or the bus system and the cost of a nf'w rider on ligh t rail was between S6 and SIO. This is very significant, c o nsid ering that the rail routes replaced the most po p ula r bus ro utes T h e experie nce of all th ree c i t ies suggests that improvements in the respective bus systems probably w ould have been muc h wiser (GomezIbanez, 1985). Lowdensity sprawl pre sents a most difficult challenge for public transit systems. In a setting of disp ersed rcsi-

PAGE 16

dences, workplaces, and facilities, it is extremely expens ive and difficult to provide an adequate level of public transit service to the outer fringes of this area. Webster and Bly show that when a trip originates and ends in the outer fringes, the automobile p rovi des a much faster and convenient mode of transportation (\Vallis, 1991). Thus, the problems facing public transit in the United States, a country of sprawling communi ties and extremely high levels of aut omobil e ownership, are not only obvious they arc enormous. This difficulty to compete wit h the private automobile is reflected in the level of demand for public transit. As shown by Webster and Bly, with a drop in demand, public transit receives revenues and must cut its level of services which, in turn, result s in further reduc tions of demand To avoid lowering service levels, subsidies are needed t o offset red u ctions in demand. It is felt by some that subsides merely act to further lower the cost of all forms of transporta tion, w hich are underpriced anyway, which, in turn, facili tate s more sprnwl. 1990 T h e debate over sp raw l has led many to believe that compact development is the m ost prefera b le urban form Some, however, are not so qu. ick to attack spra wl. Some believe tha t the ideal compact f orm tha t is being promoted is not realistic a n d 1nerely the latest urban utopia to try to solve society's ills. Audirac et. al. (1990) point out that the pursui t o f compact development nm.s counter to America's preference for low density and suburban l ifestyles, espe<:ially in Florida. The perceived amenities of rural areas induce many Florida residents to accept longer commu ting times to live in such areas. This concurs with public opi nion studies for the l ast 50 years. Despite this overw h elming prefe rence of the public, u rban utopias of mixed-use developments and urban villages have been gaining endorsement by local governments. Even in Florida, Audirac notes that pol icies to limit sprawl and promote compact development were recom mended by the Governor's Task Force on Urban Growt h Patterns. The task force's report calls for incentives to be provided for compact urban develop ment and the promotion of public transit and in fill development (Florida Depart ment of Community Affairs, 1989). Iofill development occurs when develop ment takes place on vacant prope rty within an existing u rban area. Infill developmen t seeks to avoid the capital costs of infnstructure by assuming that all the i nfrastructure necessary to support the development is already in place. A st udy of this t heory was conducte d by Falconer and Frank (1990) i n Orlando, Florida, who reveal that spare infrastruc ture (..-a,pacity, c:,.-pecially in transponation, does not always exist and varies by location. This now leaves open the question again of which type of development, io fiU or fringe, will be more expensive to accommodate. T h e decline of the central business district is well documented. Edwards (1991) shows that to serve downtown, the City o f Atlanta has spent $1.4 billion in freeway improve ments and $2.5 billion i n transit improvements to serve downtown, yet the largest retail establishment in down town Atlanta is closing, and the space does no t have a prospective tenant. Infrastruc t u r e is being built in suburbia at tremendously inflated costs, while t her e is surplus infrastructure in the centra l business distr ict In a typic:d suburban retail center, traosponation access can only be supplied by private vehic l e (Edwards, 1991). Edwards also maintains that the l'vlAR T A system in Atlant.1, a lth ough it serves on ly a limited part of a growing met ropolitan region, is considered a success by the city.

ID STA, 'I"RAHSPORTATUIM POutY OOTIATIVE having a large financial base, rnay not feel the effects of increased infrastructure costs, but many smal l towns may see a weakening of the urban centers as subu_r.. ban retail facilities become more nant. The implementation of stricter air qu ality regulations found in the Clean Air Act will affect land use and urban deve lop ment. Epstein (1992) indicates that seeking a better integrated mass transit system may constrict lhe deve lopment of far flung housing or isolated commercial development. Zupan (1992), in a study o f transportation demand management, concludes that a population density of at least 3000 people per square mil e was the minimum necessary to provide a suffi cient level of demand for publi c transit H e further concluded that an economic activity clustering of 5 m illion square feet is needed t o support a minimum bus service and at l east 20 million square feet to support an express bus service. Wallis (1991 } examined Avalon, a new urban village in central F lorida, and found several diff e rent arguments for and against these villages. Since Orlan do has adopted a "pay as you grow" ph i l osophy, a service boundary has been defined where urban services will be provided by lite City. Developers that build outside these boundar i es must accept the burden of infrastructure costs. Tom Pelham, a former Secretary o f Florida's Department of Community Affairs, suggests that "the new towns should be l o cated well beyond existing urbanized are.as, whe .re there is littl e chance that they will contribute to sprawl." On the other side, Peter Kanovos, presid ent of the group deve lop i ng Avalon, says that t hes e urban villages are part of the solution lO urban sprav.rl, not the problem He mainta i ns that Avalon's design will have high internal trip capture (more tri ps within the community) (Wa ll i s, !991}. In the United State:;:, the automobile has been subsidized directly through hig hway funding policies. Hanson (1992) quantifies these subsidies and consi dered their significance for transportation and land use policy. He calculates these subs idies base d on Wisconsin Department of Transportation data and finds that "if transportation costs become low enough, there ls li ttle advantage -to being near an urban center." This automobile subsidy is any direct cost in prov id ing for the automob i l e system that is not paid for privately. In Wisconsin, all unitS of government spend approximately $1.4 billion per ycor on roads, half of which are paid directly by State and federal user fees. The re main ing half are paid w ith loca l revenue s such as property taxes. \"(/isconsin assumes greater financial responsibility for roads s erving a travel mobility function than a property access one. Hanson considered expenditures and prop erty taxes, the primary source of loca l revenue, for varying sizes of communities In lvlilwau kee, highway expenditures amounted to S107 million in 1987, with $81 million remaining as the lo cal bu r den. The loco! burden of highway costs is very substan t ial, representing 59 percent of the l o ca l levy. Hanson's data demonstra te that across rural and urban areas, there is consider able subsidy provided to highway users." In the long run user fees end up paying for the majority of cost of t rave llin g by automobile T hi s subsidized transporta tion cost, primarily for the automobile, has produced a pattern of sprawl that would not have otherwise occurred. The logic and methodology of the study are correct, but actual additional transporta tio n cost s for sprawl development are lack i ng. The perception of u rban sprawl in F lorida is that it i s costly and ugly and

causes mass environmental damage. The Florida Dep artm ent of Communit y Affairs and other State agencies call for containing u rban s praw l and promoting compact development. Audirnc (1990 ) poi n ts out that close scrutiny of the assumptions based o n a pejorative view of sprawl reveal that t hey can be biased. Although a compact form, j n a utopia, reduces transportat ion and infrastructure costs, in modern times people s prefer ence a nd tastes s ho w a propensity to settl e in low density are a s. Audirac ci t es a Bureau of Economic an d Business Research Survey in which it was rep o rted that Flor id ians believe that, w ith their experience with urban congestion a nd crime, t hey would rather live in suburban an d cxurban ;treas.

This issue is s till i n heated debat e and an ecumenical answer seems remote.

Conclusion A lthough the literature on the nature and impacts of urban sprawl has been expan s ive t.ransport'ation costs of sprawl have no t been quantified substantially. It is clear that extensive research focused specifically on sprawl's impact upon t ransportation costs needs to be conduct ed. Additionally, the emergence of new travel behavior patterns and the develop ment of the po l ycentric urban form make many past studies and theories obso l e t e Wit h out further study, it will be difficult to judge the performance of recent local govern ment po licies su c h as growth management plans and infiU develop ment. Answers to the question of how sprawl impaCts t r ansportation costs cou l d hel p decide how future transpon:ation do.Uars are spe n t especiall y in cases of mass transit ptojects Pub lic transportation ha s not solved all the p r oblems of urban sprawl, and the literature ind icates that it is used sparingly; t he aut omobile remains the desired mode of transportation in the Uni ted States. A l t hough mass transit is promoted as a cure for many t ransport t ion prob lems, t he r elative l y unimpressive record of recent cosdy mass transit projects has not been promising Future studies on sprawl's im pacts on transportation costs should consider that no one clear definitio n of spraw l has been established and that this introd uces subjectivity and ambiguity to the issue.
