On-ramp Signal Control Strategy of Expressway Based on Green Wave Traffic at Junction
Based on the green wave traffic at the entrance ramp and intersection of the expressway,a signal control model for the en-trance ramp of the expressway is constructed.Algorithm verification of intelligent control scheme through the elevated Yuxi Road in Hefei City,and the results showed that the intelligent control scheme improved the service level of the expressway during the evening peak hours,maintaining a reduction rate of over 20%in the main line travel time of the expressway,the traffic flow increase rate was more than 40%during the evening peak hours,and increasing the main line speed by over 30%.
