Speeding San Antonio's Commuters AlongSan Antonio, Texas, the ninth largest U.S. city, has grown around its roadway network, leaving little room to build additional roads to serve an ever-growing population and booming tourist industry. Using the existing automated traffic management system (ATMS) infrastructure, the Texas DOT, in cooperation with the Federal Highway Administration, is exploiting new technologies to extend the ATMS's capabilities and alleviate the City's traffic congestion. The implementation of those technologies is called the Model Deployment Initiative (MDI). Eight projects are part of this MDI program including development of public-access kiosks with real-time traffic and road condition information. The kiosk system will receive traffic data from the ATMS, bus route information from the transit system, hourly weather updates including a radar map and five-day forecast, and airline information. Current traffic conditions will be distributed over a subcarrier to a network of touch-screen kiosks built by Southwest Research, an applied research and development organization in San Antonio, using ESRI's MapObjects and NetEngine technologies. The kiosks would also be used to determine potential bus routes that run near the kiosk's location. Route-guidance application program interfaces were developed for the system using ESRI's new NetEngine software. "The kiosk becomes the user's starting location. The viewer selects a point of interest or enters an address, and the route is automatically calculated and displayed," explains Stephen Novosad, a senior research analyst with Southwest Research Institute. The user has the option to include real-time impedances, such as current traffic conditions, into the route-planning algorithm or have the system use stored information. "The real-time option would send them around a traffic accident or construction zone," notes Novosad, "while the stored information would only indicate the fastest route."
