The number of websites worldwide containing real-time traffic congestion data for urban areas has grown significantly over the last several years. Nearly all of these sites report exclusively on real-time freeway conditions. Typically, nearby signalized surface-street (arterial) facilities are displayed (at best) as points of reference. Several Advanced Traveler Information Systems (ATIS) providers are now weighing the benefits of integrating arterial travel time data into their freeway-based websites. In Seattle, the potential annualized benefit of an arterial data integration project is currently under study as a part of the ongoing FHWA Metropolitan Model Deployment Initiative (MMDI) program. Using large-scale traffic simulation, preliminary results indicate that delay reduction benefits for pre-trip information users in the corridor may increase as much as 125% when real-time arterial travel time data is made available.
