Previous traffic control models were usually developed on small or medium sized road *** traffic control models applicable to large-scale road networks have received growing *** this study,we develop a new mobility field and gradient-based traffic signal control approach applicable to large road ***,we introduce an emerging analytical technique,the mobility field approach,to generate the mobility field of urban travels and measure the gradients of the mobility ***,a gradient-based approach is proposed to identify the signalized intersections for implementing traffic ***,a gradient-based traffic control model is developed to alleviate traffic congestion during mass events.A new solution algorithm,termed DBSCAN-FW-GA,is proposed to solve the developed traffic control *** developed mobility field and gradient-based traffic signal control approach is validated using actual road network data and travel demand *** indicate that the proposed new traffic control approach can reduce by 17.97%the travel time compared with the widely used perimeter control approach.
