Real-Time Information: Quantifying Traveler Benefits and Effects on Transportation Demand

One approach to mitigating traffic and the resulting strains on the transportation system is to shift focus from supply to demand. When provided with good information and sufficient motivation, users of a transportation system can make decisions that will result in reduced demand on the system, decreased gridlock, increased transit ridership, and reduced need for additional lanes. A range of information systems provide travelers with the real-time data to influence travel demand. Information on traffic and weather conditions is accessible pre-trip via phone, Internet and other sources. Data provided to travelers while en route via 511, roadside message signs, and onboard information systems can have an even more immediate impact on travel behavior. Consensus among transportation agencies is that these and other real-time traveler information systems can be an effective tool to reduce transportation demand and provide direct benefits to transportation users. Still lacking, though, are the quantified benefits of such systems. Several research questions remain to be addressed. The proposed research will evaluate the value of traveler information services and address if the value can be quantified. The research will also evaluate the benefit of collecting, processing, and sharing real-time data given limited transportation agency budgets. The results of this research are expected to be immediately implementable, providing transportation agencies with the critical information needed to perform benefit-to-cost analysis, to analyze expected impacts on demand, and ultimately to justify investment in new or continued deployment of real-time traveler data systems. Transportation agencies will have assurance that they are targeting their limited funds toward technologies that are most likely to improve the nation's highway system and deliver maximum benefit to travelers. </font></p>
