基于电子警察技术的城市外地车关网收费系统

本文针对由于目前城市对外地车进城收费的收费站布局不太合理,不能起到全面收费的作用,从而对主要道路交通顺畅带来负面影响的情况,将电子警察这一城市道路交通管理的高技术手段,与外地车进入城市的缴费系统设计有机的结合起来,提出在城市外地车收费方面采用基于电子警察技术的城市外地车联网收费系统的设计方法,对其中保障该系统正常、高效工作的联网收费、车牌自动识别等关键技术进行了详细的分析。从而把电子警察技术的应用拓展到城市交通收费领域。

The on-line Toll System Based on Electronic Police Technology for the Nonlocal Cars

The toll stations are set up in the entrances of the cities to charge the tolls, which is the economic means to make the nonlocal cars pass by the city through the extramural freeway. In this case the number of the nonlocal cars which pass by the city through the in city roads to save money will decrease, consequently the traffic pressure of the city will relieve. But now there are some serious problems in the operational modes aiming to the tolls of the nonlocal cars. The first and foremost is that the small space of the toll stations makes the time of queuing last so long, especially in some stations by which a large amount of nonlocal cars pass. This undoubtedly causes the traffic jams. In addition, the locations of the toll stations are not entirely reasonable. Some of them are easily to be the blind spots for charging the tolls of the nonlocal cars. Some nonlocal car drivers who are not self-conscious may consider it a great opportunity to escape from the responsibility of the tolls. Last but not least, the contradiction between the increasingly busy traffic service administration and the deficient police is evident. The personnel working in the toll stations sometimes feel so tired that they may mistakenly charge the tolls in the process of charging, which will definitely make the nonlocal car drivers discontented. In this circumstance, a new operational mode aiming to the tolls of the nonlocal cars is required to meet the two vital demands. One is that the vehicle speed should not be influenced when being charged and the vehicle flow should be expedited in order to reduce the traffic jams. The other is the operational mode should avoid the charging blind spots because of the unreasonable locations of the toll stations. Thereby, the design that charging the tolls of the nonlocal cars through the bank on-line tolls technology and the supervising the nonlocal cars by the advanced surveillance system of the traffic roads comes into being. This paper takes Guangzhou city as a typical example, combines the electronic police technology which is the hi-tech means of traffic administration with the toll system of the city, and proposes the design for the on-line toll system based on electronic police. technology for the nonlocal cars, thus it solves the problem that the arrangement of the toll stations for the nonlocal cars is not reasonable, which can not play a role in tolling all around but bring the negative effect to the situation of the main road traffic of cities. And it amply analyses the vital technologies of the normal and high efficient work for the system, such as the on-line toll technology and the automatic recognition of vehicle license technology. In this way, the application of electronic police technology will expand to the domain of the urban traffic toll. This system is able to exert the administrative superiority of intelligence and bring up the veracity and efficiency of the traffic execution. As a matter of fact, this system absolutely boosts the efficiency of urban traffic and social benefit greatly.
