Effect of Real-Time Passenger Information Systems on Perceptions of Transit’s Favorable Environmental and Traffic Reduction Roles

A two-wave survey of faculty, staff, and students at a large university was conducted to study the perceptions of and attitudes toward several dimensions of the university bus service before and after the implementation of a real-time passenger information system. In this study, community perceptions of the bus service's role in enhancing the environment and reducing traffic were investigated. Results showed that both users and nonusers of the bus service had positive perceptions of the bus service's environmental and traffic reduction roles, that those who noticed the recently implemented real-time information system had more positive attitudes, and that the effect of the information system on the perceptions was as great or greater for those who did not use the bus service as it was for those who used the service. It is hypothesized that these results, especially if confirmed in different communities, could motivate transit agencies to promote environmental and traffic reduction benefits of transit to gain public support of nonusers for transit subsidies and to market high-tech and progressive investments to increase support among nonusers.
