Cooperative traffic light control - considering cyclists with the aid of V2I
summary
A cooperative traffic light control called CTLC model uses V2I from cyclists’ Mobile Devices (smartphone, smartwatch, or bike on‑board unit) to send position, speed, route and predicted arrival so the controller requests and adjusts phase durations; the mobile app returns a GLOSA function with estimated signal times and speed recommendations. A Python controller couples to SUMO via TraCI+SUMO coupling and simulates a Braunschweig intersection, showing fewer cyclist waits and stops (≈160 cyclists/h scenario) while motorized delay stays stable or slightly improves.
