| 摘要： | The Virginia Department of Transportation (VDOT) has invested in extensive closed circuit television (CCTV) systems to monitor freeways in urban areas. Generally, these devices are installed as part of freeway management systems (Smart Traffic Centers, STCs). While CCTVs have proven to be very effective in supporting incident management, they simply provide images that must be interpreted by trained operators. Recent studies completed by the University of Virginia (UVA) and the Virginia Transportation Research Council (VTRC) concluded, however, that it is feasible to integrate CCTV with video image vehicle detection systems (VIVDS), which are currently on the market, to provide the ability to measure traffic conditions. Given this positive result, it is advantageous to pursue other data collection applications of an integrated CCTV/VIVDS. The purpose of this project was to develop and field test a prototype CCTV/VIVDS integrated system (referred to as Phase III Autotrack) that adds the functionality of shoulder detection to the existing traffic data collection capabilities of the previous prototype (Phase II Autotrack). Shoulder detection allows STC operators to improve the safety and efficiency of the freeway system by rapidly responding to vehicles stopped or stalled on shoulders. |
