随着社会的快速发展,人们的生活质量不断提高,城市车辆的数量也在不断增多,城市交通压力不断增大。如今,城市智能交通系统的应用范围不断扩大,城市智能交通系统包括以下环节:一是交通信息服务系统,二是车联网系统,三是自动驾驶系统。相比而言,西方国家应用城市智能交通系统的时间比较长,经验丰富,我国应用城市智能交通系统的时间比较短,还处于摸索阶段。对此,我国必须加大城市智能交通系统的研究力度,合理借鉴西方国家的先进经验。 With the rapid development of society, people’s quality of life continues to increase, the number of urban vehicles is also increasing, and urban traffic pressure is on the rise. Nowadays, the application scope of urban intelligent transportation system is expanding constantly. The urban intelligent transportation system includes the following links: one is the traffic information service system, the other is the car networking system and the third is the autopilot system. In contrast, the application of urban intelligent transportation system in western countries takes a long time and is experienced. The application of urban intelligent transportation system in China is relatively short and is still in a groping phase. To this end, China must intensify the research on urban intelligent transportation system and draw lessons from the advanced experience of western countries rationally.
