It finds that cities with large, well-established rail systems have significantl y higher per capita transit ridership, lower average per capita vehicle ownership and annual mileage, less traffic congestion, lower traffic dea th rates, lower consumer expenditures on transportation, and higher tran sit service cost recovery than otherwise comparable cities with less or no rail transit service. This indicates that rail transit systems provid e economic, social and environmental benefits, and these benefits tend t o increase as a system expands and matures. This report discusses best p ractices for evaluating transit benefits. It examines criticisms of rail transit investments, finding that many are based on inaccurate analysis .
For this study, US cities were divided into thr ee categories: 1 Large Rail Rail transit is a major component of the transportation system. When these groups are compared, Large Rail cities are found to have signi ficantly better transport system performance. Compared with Bus Only cit ies, Large Rail cities have: * 400% higher per capita transit ridership (589 versus 118 annual passe nger-miles).
This graph shows the far higher rates of transit ridership and transit co mmute mode split in "Large Rail" cities. The dashed line at 100% indicat es "Bus Only" city values.
This graph compares different categories of cities by var ious performance indicators. The dashed line at 100% indicates "Bus Only " city values. These benefits cannot be attributed entirely rail transit. They partly re flect the larger average size of Large Rail cities. But taking size into account, cities with large, well-established rail transit systems still perform better in various ways than cities that lack rail systems. Thes e benefits result from rails ability to help create more accessible lan d use patterns and more diverse transport systems.
In Bus Only and Small Rail cities, congestion costs tend to increase with city size, as indicated by the dashed curve. They have substantially lower congestion cos ts than comparable size cities. As a result, New York and Chicago have a bout half the per capita congestion delay of Los Angeles. Although Large Rail cities have higher per capita congestion costs, this occurs because congestion tends to increase with city size. Taking city size into account, rail transit turns out to significantly reduce per ca pita congestion costs, as indicated in Figure ES-3. Matched pair analysi s indicates that Large Rail cities have about half the per capita conges tion costs as other comparable size cities. However, economic benefits more than re pay these subsidies: rail transit services are estimated to provide $19. Rai l transit also tends to provide economic development benefits, increasin g business activity and tax revenues. Additional, potentially large benefits include improved mobility for non-drivers, increased community livability and improved pu blic health. This study critiques studies which imply that rail transit is ineffective . It finds that their analysis is often incomplete, inaccurate, and bias ed. It examines various factors that could offset rail transit benefits, including the possibility that transit oriented development is harmful to consumers, that new rail systems cannot achieve significant benefits, that apparent benefits of rail actually reflect other factors such as c ity size, and that bus transit can provide equal benefits at less cost. This study indicates that rail transit is particularly important in large , growing cities. Large cities with well established rail systems are cl early advantaged in terms of congestion costs, consumer costs and traffi c crash rates compared with cities that lack such systems. Cities with n ewer and smaller systems have not yet achieved the full impacts, but, if their rail systems continue to develop, their benefits should increase for decades, and so are a valuable legacy for the future. This analysis does not mean that every rail transit project is cost-effec tive, or that rail is always better than bus or highway improvements. It attempts to provide a fair and balanced evaluation of the advantages an d disadvantages of each mode, and identify situations in which each is m ost appropriate. This study concludes that rail transit provides signifi cant benefits, particularly if implemented with supportive transport and land use policies. In many situations, rail transit is the most cost ef fective way to improve urban transportation. Introduction During the last century most North American cities became increasingly au tomobile oriented (for this analysis "automobile" refers to any personal motor vehicle, including cars, light trucks, vans, SUVs and even motorc ycles). Now, the majority of personal travel is by automobile, the major ity of transportation resources (money and land) are devoted to automobi les and their facilities, and many communities have dispersed land use p atterns that depend on automobile travel for access. The resulting growt h in vehicle traffic creates various problems, including congestion, hig h road and parking facility costs, costs to consumers of owning and oper ating automobiles, traffic accidents, inadequate mobility for non-driver s, and various environmental impacts. In recent years many experts and citizens have advocated diversifying our transport systems by increasing support for alternatives modes such as walking, cycling and public transit. To accomplish this many cities are making significant investments in public transit, including busways, lig ht rail and heavy rail systems. There is considerable debate over the me rits of these investments. This study evaluates rail transit benefits based on a comprehensive analy sis of transportation system performance in US cities. It uses best av ailable evaluation methods, based on guidance from leading experts and o rganizations (Cambridge Systematics, 1998; This analysis takes into acc ount a variety of performance factors, including the amount and type of travel that occurs, congestion costs, road and parking facility costs, c onsumer costs, accident rates, transit system efficiency and cost recove ry, and various other impacts. This study compares rail and bus transit, identifies the conditions in wh ich each is most appropriate, and discusses the role that each mode can play in an efficient transportation system. It also describes various wa ys of improving transit service performance in order to increase benefit s This study evaluates various criticisms of rail transit, including claims that it provides minimal congestion and emission reduction benefits, th at it is not cost effective, and that money is better spent on roads, bu s service or subsidized cars. It also examines various factors that coul d offset rail transit benefits, including the possibility that transit o riented development is harmful to consumers, that new rail systems canno t achieve significant benefits, that apparent benefits of rail actually reflect other factors such as city size, and that bus transit can provid e equal benefits at less cost. The Analysis This section describes the evaluation of rail transit benefits. About two dozen US cities have some sort of rail transit service, but m ost are small and so cannot be expected to significantly effect regional transportation system performance, although they may have significant i mpacts on a particularly corridor or within a particular area. For this study, US cities are divided into three categories: 0 Large Rail Rail transit is a major component of the transportation system.
This figure shows the portion of commutes by rail and bus transit. Only a few cities have rail systems large enough to significan tly impact regional transportation system performance. The next section of this report evaluates these different categories in t erms of various transportation system performance indicators. Becau...
