A novel vehicular traffic management system that requires no special equipment in any vehicle is disclosed. More specifically, the novel system may be used when approaching a lane closure or lane reduction. The system comprises sequencing signaling devices along the roadway and a central controller. The controller commands the signaling devices to flash (or signal) according to a calculated trajectory. Vehicles traveling along side the signaling devices can pace their speed with cues from the signaling devices. Through this pacing, the system can position the vehicles such that they can merge safely and efficiently. The system can be expanded to merge more than just two lanes. Further refinements to the system include external connections that may include GPS tracking and Internet down/uploading. A feasibility condition/determination can be used with the system to make the system even more robust and efficient.
