Intersection Braking Guidance for Trams Based on Lineside Signs
Trams need to brake frequently due to signal control and safety speed limits at intersections.Due to the inaccuracy of distance judgment,tram drivers tend to reserve extra braking distance at intersections,resulting in lower braking coefficients and a decrease in speed.An intersection braking guidance method using lineside signs is proposed for trams to reduce braking distance redundancy and improve running speed.Drivers are guided to brake with the shortest possible distance by marking the initial braking position and speed of trams with fixed lineside signs.A tram driving simulation system was developed based on a vehicle dynamics model.Simulation scenarios were then created using VISSIM.The driving simulation experiments show that this method standardizes the driver's braking behavior,improves braking efficiency,reduces the randomness of braking operations,and therefore has a positive effect on speed improvement and time stability.
