Congestion pricing is a means of optimizing the use of a road through charging a fixed or variable fee for the use of it. Transportation professionals and politicians are increasingly interested in using congestion pricing as a promising, cost effective solution to congestion and air quality problems. It is seen as an attractive alternative to costly and often politically difficult capital investment and regulatory altematives. In addition it can be an effective means of generating revenue.
The Interstate 15 (I-15) Congestion Pricing Project is a federally-funded, three-year demonstration program which allows single occupant vehicles (SOVs) to use the existing carpool, or high occupancy vehicle (HOV) lanes on Interstate 15 (also known as the 1-15 Express Lanes) for a fee. Phase I of the project was known by customers as the ExpressPass program. In the first phase, payment for use of the HOV lanes was through purchase of monthly passes.
The project began in December 1996 and is generating revenue for transit service improvements in the 1-15 corridor. The project is managed by the San Diego Association of Governments (SANDAG). San Diego State University is responsible for the independent monitoring and a multi-element evaluation of the project. A full report for this study element is to be found in Golob et al 1998.
This paper provides a brief overview of the project and then reports in more detail on first year results from a multi-wave panel of commuters which has been established to monitor the impacts of the project on travel behaviour.
