Summary
This report evaluates the Bellevue Smart Traveler (BST) project, an Intelligent Transportation System demonstration aimed at reducing single-occupancy vehicle (SOV) commuting in downtown Bellevue, Washington. Motivated by the need to make high-occupancy vehicle (HOV) commuting more attractive, the study sought to determine if innovative communication technology could facilitate dynamic ridesharing and provide real-time traffic and transit information. The project, conducted by the University of Washington in partnership with TransManage and PacTel between 1992 and 1994, designed and tested a Traveler Information Center (TIC) prototype to help commuters form flexible ride groups. The research methodology began with a literature review and a comprehensive user needs assessment involving surveys, telephone interviews, and focus groups of employees at the Bellevue Place office complex. These assessments identified key requirements, such as the need for instructional information, security features, and a "guaranteed ride home" service. Based on these findings, the team developed a TIC prototype accessible via touch-tone telephone and alphanumeric pagers. The system allowed users to offer rides, search for matches, and receive traffic and transit updates. A role-playing usability test with eight participants refined the interface before a five-month public demonstration. During the demonstration, usage was tracked via system logs, and participant feedback was gathered through three telephone surveys and a final completion questionnaire. The results indicated that while participants appreciated the technology and the concept of dynamic ridesharing, they largely failed to form actual ride matches. Of 53 registered users, only 48 formed ride groups, and merely six matches were logged. Participants expressed a strong preference for offering rides rather than accepting them, citing discomfort with entering strangers' vehicles and inconvenience as primary barriers. Technical limitations also hindered success; pagers displayed too few ride options, and the lack of HOV lanes in the area removed time-saving incentives. Furthermore, the recruitment strategy attracted technology enthusiasts who did not necessarily require ridesharing services, skewing the user base. Usability testing revealed that while tech-comfortable users succeeded, those less familiar with technology struggled with menu navigation and confirming rides. The study concludes that dynamic ridesharing is primarily a social experiment requiring significant behavioral change, rather than just a technical solution. The authors assert that people prefer to offer rides over accepting them and that the factors constituting a viable ride group require further exploration. Recommendations for future implementations include enhancing pager capacity, integrating two-way paging for faster matching, providing hands-on training, and establishing predetermined pickup points to increase safety and convenience. The report suggests that financial incentives and management support are likely necessary to overcome the inherent flexibility and convenience advantages of SOV travel.
Key finding
Participants preferred offering rides over accepting them, and despite positive feedback on the technology, only six ride matches were logged during the demonstration due to user discomfort and logistical barriers.
