Abstract
Employer ridesharing programs and employee mode choice were analyzed using Southern California data. Problems in estimating the costs and benefits of employer ridesharing programs were identified. Surveyed firms used a wide variety of information to estimate employee mode split internally. Virtually all surveyed firms offered free or subsidized parking to some or all of their employees. Few responding firms estimated the cost of providing employee parking accurately, if at all. Despite these significant data limitations, factors influencing firm choice of employer ridesharing program components were identified. The influence of employer ridesharing programs on employee mode choice was modeled using weighted least squares logit regression analysis. Firm size was foung to be the single most important variable identified in the analysis. Larger firms were more likely to offer ridesharing incentives to their empolyees, and to report direct employer benefits from ridesharing. Alternative work hours hindered the formation of ridesharing arrangements in some cases. Relatively few firms promoted ridesharing on a purely voluntary basis. A private market for employer ridesharing services was found to exist, however. Personalized matching assistance may be a critical factor in developing more effective employer ridesharing programs. Parking pricing and supply control measures probably would have a larger impact on employee mode split overall. Parking management faces severe obstacles in implementation, some of which might be overcome through the more extensive provision of ridesharing services, such as personalized matching assistance. to employees at specific employment sites by their employers.
