| 摘要： | The Arizona Department of Transportation (ADOT) maintains a variety of independent applications to monitor roadway conditions and activities across the state including traffic counts, weather data, signal timing, Variable Message Sign (VMS) advisory messages, video signals, and statewide Highway Condition Reporting System (HCRS) events. Each ITS field device has its own proprietary device driver application and output data stream format. This report summarizes an Intelligent Transportation Systems (ITS) research program by ADOT to consolidate statewide user workstation access to a subset of the various ITS field devices via a 'single-screen.' The implementation of this ability involved the development of software interfaces with device driver applications via the Internet and intranet. This resulted in the centralization and improved availability and archiving of traffic data derived from the associated ITS field devices, as well as data from the Advanced Traveler Information System (ATIS) via the HCRS. This outcome improved the real-time aspect of the operational management of the state highway system. Ultimately, the driving public will be able to plan their travel with more consistent, reliable and timely information via the Internet, and access this real-time information en route via the 511 Interactive Voice Response system (IVR). A second project phase introduced a graphical interface to HCRS to automate location information and improve data entry accuracy for field operations staff. |
