Variable speed limit control is an important means to alleviate highway traffic congestion. Its principle is to prevent traffic capacity degradation in bottleneck areas by speed limiting. With the development of intelligent network connection and vehicle-road cooperation technology, the controllable degree of intelligent vehicle has been greatly improved, which provides a prerequisite for improving the performance of control. Improvements have been made implemented on the sliding mode reaching law formula, leading to the development of a formula incorporating a filter factor. Building upon this advancement, a VSL control model employing the novel sliding mode reaching law is put forth, with the stability demonstrated through analysis using the Lyapunov function. By constructing a simulation platform with SUMO and VEINS for analysis. Results showed that the new model saves 9.5% of total travel time and 10.9% of total delay compared to the classical PID feedback control algorithm. Moreover, the new model is more stable and solves the problem of speed oscillation in the speed limit zone.
