Aiming at the uncertainty of actual running speed of vehicles,the influence of speed variation on actualresults of green wave coordination control scheme for traffic signals is analyzed.Then,by determining the velocityband of normal moving vehicles and by setting the average design speed for green wave coordination control,alter-native schemes of arterial green wave coordination control are generated.Finally,on the basis of green wave band-width expectation,the alternative schemes are evaluated and optimized under corresponding velocity distributions.The results of example analysis and simulation show that the proposed method takes into consideration the velocityband and distribution in different arterial directions and helps choose the best green wave coordination controlscheme from many alternative schemes according to sampled data and probability distribution of actual runningspeed.Thus,it is efficient in realizing the quantitative risk evaluation of coordination control schemes for traffic sig-nals and improving the adaptability and robustness of arterial green wave coordination control schemes.
