Trip Reduction Programs
Trip reduction programs are the result of local, state, or regional government requirements aimed at encouraging the use of transportation alternatives to single-occupant vehicle travel. Such options include ridesharing, public transit, bicycling, walking, and telecommuting.
The majority of trip reduction programs focus on work-related commutes and peak travel times. As such, employers tend to be the chief implementers of trip reduction programs. Some ordinances cover travel reduction related to shopping and other personal reason, and therefore may impose requirements on commercial property owners, schools, or other public service organizations as well. In some cases, local governments are required to develop and implement transportation management measures such as park-and-ride lots, high occupancy vehicle (HOV) lanes, and shuttle services to support trip reduction mandates.
The main goals of most trip reduction programs are the alleviation of traffic congestion and reduction of associated emissions that contribute to air pollution. Some local, state, and regional governments also use trip reduction programs as interim or supplemental solutions to address financial difficulties tied to adding new transportation capacity for growing demand and to delays in implementing transit improvements.
In addition, public concerns about the social and environmental impacts of transportation capacity expansions and pressure to minimize traffic implications associated with new development in rapid-growth areas have spurred a move toward trip reduction programs in some areas.
Policy Approaches
Trip reduction policies are based on the specific needs of the local, state, or regional area. There is no single set of policies or master program for all locations or situations; rather, a broad range of trip reduction policies and programs exist. Most trip reduction policies, however, fall under one of the following general types.
Local, state, or regional governments may issue policies that encourage but do not mandate that employers provide commute alternatives information and incentives to their workforce. The same policies may require complementary actions on the part of the government to support the initiatives, such as the creation of an outreach program designed to collaborate with interested employers and their employees. The voluntary nature of compliance with these types of policies means that some employers may not wish to engage. Those that do may cease their participation at any time.
Some trip reduction requirements are included as a bargaining element for negotiations as part of larger policy plans, such as those dealing with rezoning or a major public-private development agreement. The practice enables the trip reduction program to be designed to lessen the negative impacts perceived as potential outcomes of a project. For example, the inclusion of trip reduction elements may allay fears about increased traffic congestion associated with a new development project under consideration.
Trip reduction activities are sometimes included as a requirement for developers or employers who choose to accept government financing or incentives. In these arrangements, the local, state, or regional government gains a willing partner in helping reduce traffic congestion and pollution. Similarly, trip reduction measures are sometimes incorporated into the conditions of approval for new development projects.
For example, a construction permit might require the creation of on-site parking spaces for high-occupancy vehicles or an occupancy permit might stipulate a need for an on-site transportation coordinator. These types of project requirements are negotiated on a case-by-case basis.
