Abstract: Taking advantages of the “Internet Plus”, the bottleneck of traditional traffic signal optimization techniques will be able to overcome. Learning from the practical experience, this paper states the bottleneck of the traditional signal optimization techniques, and discusses e corresponding solutions under the “Internet Plus”. A series of enhanced approaches are further proposed, including trouble-shooting in an active manner, development of an accurate optimization scheme, and evaluation of optimized results. Specifically, the paper tries to adopt the “Internet Plus” data to validate the model and improve simulation accuracy. The results show that the “Internet Plus” technique has a capability of better optimizing signals, increasing the adaptation level between the scheme and traffic flow, and effectively alleviating traffic congestion.
