The invention belongs to the technical field of expressway design, construction, operation and maintenance and vehicle-road cooperation, and provides an expressway and an expressway electrification control system and method.Pantograph charging systems are arranged on the two sides of a middle isolation belt of the expressway, and a photovoltaic power generation system is arranged on the middle isolation belt; the pantograph charging system is connected with the photovoltaic power generation system or the power grid through the control switch, and the monitoring system detects weather conditions; the controller controls the control switch to connect the pantograph charging system with the photovoltaic power generation system or the power grid according to weather conditions, so that the energy consumption of the power grid is reduced; the vehicles running on the lanes on the two sides of the middle isolation strip can be charged in the running process, the problems of long charging time, charging queuing and the like are solved, and when other vehicles merge into the formation vehicles in the lanes on the two sides of the middle isolation strip, factors such as the charging time of different vehicles and the charging waiting time do not need to be considered, so that the charging efficiency is improved. The data volume needing to be processed is reduced, and the control difficulty is lowered.

本发明属于高速公路设计、建设、运维及车路协同技术领域，提出了一种高速公路、高速公路电气化控制系统及方法，在高速公路中间隔离带两侧设置电弓充电系统，以及在中间隔离带上设置光伏发电系统，电弓充电系统通过控制开关与光伏发电系统或电网连接，监控系统检测天气情况；控制器根据天气情况，控制控制开关将电弓充电系统与光伏发电系统连接还是与电网连接，降低了对电网的耗能；行驶在中间隔离带两侧车道上的车辆在行驶过程中即可完成充电，解决了充电时间长、充电排队等问题，并且其他车辆汇入中间隔离带两侧车道中的编队车辆时，不需要考虑不同车辆需要充电的时间和所需要充电等待的时间等因素，减少了需要处理的数据量，降低了控制难度。
