Research related to factors influencing an individual's propensity to carpool or vanpool is briefly reviewed to provide background for the findings of a survey of the general commuting population of suburban Orange County, California. The findings are presented as they relate to three groups of commuters: ridesharers, solo drivers, and the general commuting population. Comparisons between the survey's findings and previous research are made. Among the key findings was that travel time was the most important mode selection factor for all three groups. Whereas the availability of a car at work was the second most important factor for commuters in general and solo drivers, ridesharers rated commuting costs as the second most important factor. Ridesharers were more likely than solo drivers to believe that high-occupancy vehicle (HOV) lanes encourage ridesharing, and there was more support among ridesharers than solo drivers for a sales tax increase to build HOV lanes. The general commuter survey results support the previous findings with regard to the role of travel time and distance in commute mode choice: ridesharers commute for longer time and distances than either solo drivers or the general commuting public. Support was also provided for the role of parking cost and availability. Comparisons were also made between the data base of matchlist applicants of the regional commute management agency and the general commuting population. The commute distances of commuters completing applications for ridesharing matchlists were more like those of current ridesharers than the general commuting public or solo drivers. Also, the proportion of matchlist applicants currently ridesharing was larger than that of the general commuting public.
