To address the dynamic traffic impact of highway blasting construction, this study builds a simulation and visualization framework based on VISSIM. The framework integrates multi-source data fusion and Q-learning-based path planning to model and optimize traffic flow under blasting conditions. A vehicle conflict detection module based on SSAM is developed to evaluate safety risks. Simulation results demonstrate that the proposed approach accurately reflects traffic dynamics, improves rerouting efficiency, and reduces potential conflicts. The visual output enhances decision-making during construction planning.

摘要

To address the dynamic traffic impact of highway blasting construction, this study builds a simulation and visualization framework based on VISSIM. The framework integrates multi-source data fusion and Q-learning-based path planning to model and optimize traffic flow under blasting conditions. A vehicle conflict detection module based on SSAM is developed to evaluate safety risks. Simulation results demonstrate that the proposed approach accurately reflects traffic dynamics, improves rerouting efficiency, and reduces potential conflicts. The visual output enhances decision-making during construction planning.
