| 摘要： | The Smart Workzone (SWZ) began in the spring of 1995 and concluded in the fall of 1996 as a Minnesota Guidestar operational test project. SWZ was essentially an outgrowth of the Portable Traffic Management System (PTMS), a preceding operational test project. PTMS was developed in response to periodic traffic congestion problems resulting from major events. Through the use of non-intrusive detection devices and wireless communication, PTMS was retrofitted to form SWZ which provided real-time, site specific traffic information at selected construction sites. Central to the success of SWZ as an operational test, was the public/private partnership formed between Mn/DOT and ADDCO manufacturing. At each stage of the project, Mn/DOT and ADDCO worked diligently and cooperatively to satisfy the requirements of the project. For example, before an official agreement was drafted, MnDOT and ADDCO agreed that Mn/DOT would be the lead partner in the project, serve as the project manager, provide funding, staff and access to its Traffic Management Center. ADDCO in return would provide the equipment for the operational test, the technical expertise, software, and all systems integration. This type of segregation of duties helped to accelerate the development and operation of the test. The benefits realized from the test were substantive. ADDCO received three patents for: the Precision Pan/Tilt/Zoom unit, the Triangular Work Tower unit, and the Workzone Variable Message Signs all of which were developed specifically for the SWZ operational test. Further, SWZ was an opportunity for ADDCO to test its inventions in the “safe environment” of an operational test without the pressures and repercussions that accompany a full scale deployment of untested technologies. Mn/DOT received the use of a user friendly SWZ system that used advanced traffic detection and surveillance technologies to test the concept of portable workzone traffic management. Finally, the user response of the system was favorable. The majority of the SWZ route drivers (66 percent) surveyed remembered seeing the lighted variable message signs. Of the 66 percent remembering the VMS messages, most remembered specific messages and felt more informed about traffic conditions with the construction sites. |
