The invention discloses a road side detection unit layout and road traffic sparse sensing method and system, and provides a low-cost solution for a modern urban traffic sensing system. The method comprises the following steps: firstly, modeling a complex urban road network system provided with a road sensor by using traffic flow simulation software, and obtaining driving data of all vehicles and monitoring data of a traffic detector in simulation according to a simulation operation result; secondly, removing a part of traffic detectors in the urban road network, and recovering the traffic data of the removed part of the detectors on the basis of the existing detectors by using a sparse sensing method; and finally, taking the recovered traffic detector data as a virtual detector to replace the removed real detector in the original road network, and obtaining complete road network traffic detector data. According to the method, the data of all the detectors in the urban road network can be restored by using the sparse roadside detectors, a low-cost roadside detector layout scheme is realized, and the estimation precision is relatively high.
