| Abstract: |
| [Objective] The speed algorithm of the intersection starting wave of the vehicle was improved,in order to solve the real-time and accurate prediction of the starting wave speed.[Methods] In view of car-following dynamics,the starting speed of the vehicle is regarded as the average value of the propagation velocity of the moving state of all the neighboring vehicles in the fleet,and a new speed algorithm of the intersection starting wave is derived.[Results] Comparing the theoretical value with the measured data at a typical signalized intersection,more than 75% of samples are in the range of error allowed.[Conclusion] The scientific nature and feasibility of the new algorithm are verified.This algorithm provides a new theoretical basis for the traffic signal control of the road intersection. |
