This chapter describes “Light
Rail Transit” (LRT) systems.
Light Rail Transit (LRT, also called trams or trolleys) systems provide convenient local Public Transit service on busy urban corridors, connecting major destinations such as central business districts, medical centers, campuses and entertainment centers. LRT vehicles tend to have relatively smooth and comfortable operation, easy boarding, attractive Stations, Transit Oriented Development, and easy-to-understand routes and schedules. Many rail systems have quick loading and Transit Priority features (grade separation and traffic signal preemption) to maximize travel speeds and minimize congestion delay. They are often supported with convenient user information (many city maps show rail transit routes and stations) and other Transit Encouragement strategies to increase ridership.
There is some confusion about the definitions of different types of urban rail services. It is not vehicle that defines the transit mode, but the quality of rights-of-way (ROW). The Transportation Research Board (TRB) Light Rail Committee offers these definitions:
Light Rail Transit both requires and supports Smart Growth land use policies. LRT systems are often
implemented in conjunction with Transit Oriented
Development (common destinations are located within convenient walking
distance of transit stations). Rail Transit stations provide a catalyst for
creating compact, mixed, walkable urban centers (often called
Rail transit is considered prestigious, and so tends to be relatively effective at attracting discretionary travelers (people who have the option of driving for a given trip), and political support (many communities have passed referenda for special funding for rail transit systems).
Light Rail Transit Improvements and Encouragement Programs are usually implemented by transit agencies, often with support from other government agencies and businesses. Major rail transit investments often require special funding arrangements which sometimes require voter approval. Rail transit should be implemented with policies that support Transit Oriented Development. Groenewegen and de Boer (2005) provide guidelines for evaluating the feasibility of rail transit in a particular city.
Like any transit service, the travel impacts of Light Rail services depend on various factors including the quality of service, fares and user incentives (such as Commuter Financial Incentives), Marketing, and the degree to which land use policies support transit (Transit Evaluation). Various Transit Encouragement strategies can increase ridership.
Rail tends to be more attract than conventional bus transit to discretionary travelers (people who have the option of driving), including commuters, visitors, and people traveling to major sport and cultural events if they are located along transit lines. In addition, where LRT provides a catalyst for more accessible land use, it tends to increase overall transit transport (rail and bus), increase overall walking transport, and reduce per capita vehicle ownership and use (Litman, 2004; Lane, 2008; Kenworthy, 2008).
New North American rail systems have attracted higher ridership than would be expected based on standard modeling of service frequency, travel speed and fare (Henry and Litman, 2006; Lane, 2008). It is now common practice to apply up to a 12-minute in-vehicle travel time “bias constant” for rail rapid transit (that is, the travel times for mode-split modeling purposes would be 12 minutes shorter for rail in comparison to conventional local bus service) due to factors such as more attractive vehicles, nicer stations and improved Walkability around stations (Kittleson & Associates, 2007). This depends on specific factors, such as the quality of service provided, and the degree to which land use policies support Transit Oriented Development (Litman, 2007a).
There is some debate concerning the relative attractiveness of rail compared with Bus Rapid Transit (bus systems that provide high service quality). Some research indicates greater demand for rail than bus transit (NJARP, 2006; Henry and Litman, 2006), but some experts argue that given comparable speeds, comfort features and promotion, bus service can be equally attractive (for discussion see Litman, 2006a).

Rail Transit tends to provide high service quality. This directly benefits users, and by attracting discretionary travelers who would otherwise drive, tends to provide indirect benefits such as reduced traffic congestion, road and parking facility costs, traffic crashes, energy consumption, and pollution emissions. Although Light Rail Transit generally serves a relatively small portion of total regional travel, it tends to be concentrated in dense urban areas where vehicle traffic costs are high. As a result, total benefits per trip tend to be large. Air pollution emissions are significantly lower per passenger-mile than automobile travel, conventional transit bus and Bus Rapid Transit (Puchalsky, 2005).
Where Rail Transit is a catalyst for Transit Oriented Development and Smart Growth land use development it provides a variety of indirect benefits, including Increased Property Values near transit stations, improved community Livability, consumer cost savings and Affordability (by reducing per capita vehicle ownership and operating costs), and increased regional Economic Development (Hass-Klau, Crampton and Benjari, 2004). Although these benefits are difficult to quantify, they can be substantial (Land Use Impacts), often offsetting a major portion of public costs (Smith and Gihring, 2003).
According to analysis described in Litman, 2004, residents of cities with high-quality Rail Transit systems pay approximately $100 annually per capita in additional transit subsidies, and save approximately $500 annually per capita in direct consumer transportation (automobile and transit) expenditures, indicating a high return on investment.
Rail Transit systems tend to be expensive to develop and operate. According to American Public Transportation Association data (APTA, various years), Light Rail Transit has higher operating costs per passenger-mile than other forms of transit. However, this reflects the fact that LRT systems are located in dense urban areas where any transportation service is costly to provide, and because many LRT systems are relatively new and still building ridership. When all costs (including roadway, parking, vehicle, and external) are considered, Rail Transit is often more cost effective per passenger-trip than accommodating additional automobile travel or attracting more bus transit users on congested urban corridors. Claims that rail transit projects cost more than alternatives often consider only a portion of total costs (Litman, 2006a; Transit Evaluation).

The Equity Analysis Rail Transit is complex because it depends on the type of service provided and the perspective used. LRT services tends to be costly to provide because it is designed to provide a high quality service to attract discretionary riders on congested corridors and so requires high public subsidies per unit of capacity. It tends to benefit higher-income commuters compared with conventional bus transit. As a result, critics sometimes argue that Rail Transit is regressive. However, many light rail systems are heavily used by lower-income residents, and rail transit funding often substitutes for highway rather than bus expenditures. As a result, Light Rail investments are often less regressive than highway improvements on the same corridor, when all Costs are considered (including roadway capacity, parking facilities, external costs imposed on other road users and urban neighborhoods). To the degree that Rail Transit provides a catalyst for more accessible land use, more diverse transport systems, and less stigma associated with transit use, it benefits transportation disadvantaged people, increases Affordability, and provides Basic Mobility.

Light Rail Transit is particularly appropriate in medium and large urban areas that want to create more Diverse transport systems and Smart Growth development patterns. Light Rail systems are usually implemented by local and regional governments with federal, state or provincial support. Individual businesses and developers can support LRT politically, by locating near rail stations, and by offering Incentives for employees to use transit.

Improved Transport Choice
Light Rail Transit supports and are supported by most other TDM strategies, particularly Commute Trip Reduction programs, Transit Oriented Development, Smart Growth, Nonmotorized Transportation Planning, Station Improvements and New Urbanism. Rail Transit is most cost effective when implemented with Transit Encouragement strategies such as Commute Financial Incentives, Parking Pricing and Road Pricing. Rail Transit sometimes competes with other alternative modes, particularly Bus Rapid Transit and Ridesharing.
Light Rail Transit improvements depend on the support various government agencies. Rail Transit projects often require public support for additional funding, and the support of businesses or local residents to create Transit Oriented Development.
Major barriers to Light Rail Transit projects include limited funds for transit, unsupportive land use patterns (common destinations too dispersed to be served cost effectively by rail), and policies that favor automobile travel (such as generous parking requirements and subsidies).
Government agencies (such as the Federal Transit Administration) and professional organizations (such as the American Transit Association) provide a variety of resources concerning best practices in transit planning and operations.
For case studies and examples of many different types of successful transit improvements see the Center for Transportation Excellence (www.cfte.org); Ridlington and Gigi Kellet, 2003; “Light Rail Transit Success Stories” (www.lightrailnow.org), and TRB (2001).

The study, Economic Impact of Light Rail,
investigated the effect of trams and light rail on travel patterns and economic
activity in numerous European and North American cities. It found that property
values generally increase around rail transit stations, as summarized in Table
3. It also found that rail systems tend to increase downtown shopping visits
and retail activity (several commercial areas experienced 30-60% increases in
visitors compared before and after light rail lines opened); reduces per
household car ownership rates (households within 300 meters of a rail transit
station typically own 5-15% fewer vehicle than regional averages); and results
in more compact land use development patterns. Many businesses prefer to locate
near rail stations to improve access for employees and customers; some
employers say that employees who commute by rail are more productive since they
avoid the stress and uncertainty of driving on congested roads. In the
