| 摘要： | This project identified traffic parameters and their required accuracies for characterizing traffic flow in conventional and newer intelligent transportation systems (ITS), obtained state-of-the-art detectors and installed and evaluated them in three states having diverse climates, and studied the need and feasibility of establishing a national detector evaluation facility. Task A was devoted to identifying traffic parameters and accuracies. Task B dealt with locating surface street and freeway test and evaluation sites in Minnesota, Florida, and Arizona. Task C developed the test plans used to evaluate the detectors at Hughes and in Los Angeles before they were evaluated in the other states. Task D explained how the detectors to be evaluated were selected and then compiled specifications about detectors currently on the market. In Task E, detector setup and operation were studied as tests were performed according to the plans of Task C. Task F developed the plans and specifications for evaluating the detectors at the surface-street and freeway sites in each of the three states. Detector mounting, power availability, data recording, ground truthing, and security were addressed. Task G consisted of setting up the test sites and collecting detector performance data. The collected data were reduced as part of Task H. In Task I, the performance of the detectors was compared to the specifications developed in Task A. Task J discussed the need and feasibility of establishing permanent detector test facilities. A consensus appears to be developing for such a facility, with several universities and agencies vying for its operation. The preparation of the final report was contained in Tasks K and L. The addendum to this final report (FHWA-RD-96-109) contains additional field test results. |
