摘要

With the growing traffic incidents led by the rapid increase of traffic volume on freeways, Chinese government is facing how to ensure the efficiency and safety of the freeway system. One of the hot debates is the efficiency of Freeway service patrols (FSPs) technology in the advanced video surveillance system environment, namely dense video-based surveillance system (DVBSS). To help making a correct decision, this paper develops an effective approach to assess the effectiveness of FSPs in the DVBSS environment. This paper proposes a simulation method to measure the B/C ratios of FSPs in advanced VSS environment. B/C ratios are evaluated under four scenarios namely basic scenario, FSP1, FSP2, and FSP3. All scenarios were simulated in the 9.4-kilometer segment and data were collected from the working log of traffic monitoring center. Among all scenarios, B/C ratio of FSP1 is lowest, sometimes less than1, indicating that not all the FSPs scenarios are effective in the advanced VSS environment. However, the B/C ratios of FSP2 and FSP3 in mean cost scenarios exceed 1, represent as 4.33:1 and 3.47:1 respectively. It indicated that FSPs technology is still an effective way for traffic incident management in VSS environment. To explore the robustness of the results, authors extended the length of patrolling segment to 13.4 kilometers.
