Transit is a modal choice that can increase our transportation system's capacity and at the same time provide additional choices for travelers while furthering the region's progress towards creating great streets. An effective transit system often solves many of the issues raised by the competing interests of vehicular roadways, pedestrian facilities and bicycle facilities.
Transit network refers to the comprehensive function of a transit system that considers the role each type of transit corridor plays in the larger structure. Much like functional classification, transit networks can be thought to consist of transit corridors that operate as arterial, collector and local roadways. In St. Louis, MetroLink is considered a transit arterial, as are bus routes with the highest passenger volumes and frequencies. They carry transit passengers the most efficiently and often serve the denser commercial and mixed-use areas. Collector transit routes are those routes serving secondary arterials, or collectors, and often connecting with the MetroLink system.
There are also local bus routes, with frequent stops and less frequent service that may deliver transit passengers to less dense residential areas, for example. Achieving the balance between safety and mobility for all modes and access to adjacent land uses requires thoughtful implementation of transit and a development plan that supports the use of MetroLink light-rail, MetroBus and the supporting modes of access to the transit system, such as bicycle and pedestrian facilities and Park-Ride lots.
Transit ridership is on the rise in the St. Louis region and across the country. The recent opening of the MetroLink Cross County extension and an increase in transit-oriented development points to a growing demand for transit services.
MetroLink is the backbone of the St. Louis regional transit system. The Forest Park station is a major junction in the MetroLink system, which extends east to downtown and Illinois, and west to Lambert International Airport.
The most recent extension line, known as the Cross County extension, runs from Forest Park west to Clayton, then south to Shrewsbury (see the MetroLink map for details). The MetroBus service complements the MetroLink system by providing improved access to light-rail and serving areas not located along the MetroLink network.
Transit adds capacity to a street system without widening the street itself. Bus service can reduce the number of single-occupancy passenger cars on the street, resulting in better vehicular operations overall. Current studies show that a full MetroLink train in St. Louis removes an average of 125 vehicles from the regional road network during rush hour; a full bus removes an average of 40 cars during rush hour. Increasing ridership on our light rail and bus system reduces congestion on our regional road network.
Dedicated bus lanes and/or Bus Rapid Transit could be considered in arterial corridors for long range person movement capacity. Transit measures such as these are especially effective in areas with relatively high-density land uses that can produce stable and consistent ridership. Arterial corridors with heavy through-traffic having destinations beyond a downtown area, for example, are also great examples of corridors that should consider placing a higher priority on bus lanes.
Not only does transit reduce congestion, but it yields a variety of other benefits as well.
Transit Planning in Mixed-Use Districts
Transit-oriented development (TOD) is a type of mixed-use district and an ideal way to support both the public investment in transit infrastructure and the places surrounding transit stops. TOD can occur in a variety of forms, from new construction in an undeveloped area to infill of existing land uses surrounding a new or existing transit stop. This type of development is often moderate to high-density, mixed-use, and provides a variety of services for both those using the transit facilities and those living in the nearby neighborhoods.
In addition, the development takes special consideration of design elements that support transit, such as a high level of pedestrian and bicycle access and amenities. A variety of such development is happening along the St. Louis transit system.
The relationship between transit and adjacent land use is a powerful one and when planned appropriately, supports transit ridership and economic development simultaneously. Great Streets with transit-oriented development are the building blocks of great neighborhoods and great cities. See the Choices & Guidelines section of this guide for more information on the various design elements that contribute to great streets.
The presence of any form of transit increases the presence of pedestrians. Providing safe, efficient, and attractive accommodations for pedestrians waiting at transit stops, transferring between modes, and walking between adjacent land uses and transit services is a vital design element in promoting transit as a desirable modal choice.
Design all streets for transit.Transit routes change over time and it is important to recognize that although a street may not be served by transit at the time of (re)development, it may become a transit route in the future, particularly if the (re)development includes an increase in density of either commerical or residential uses.
