Study on city area traffic coordination control based on linear programming

A traffic network of a city area is considered in this paper. This paper presents a linear program which is based on optimization from a purely mathematical point of view to solve the problem of optimizing city area traffic control. The phase sequence of each intersection is known. The identification of the optimal phase relationship between all intersections and duration for the signal phases are combined into one problem in this paper. In particular, we consider a group of signalized intersections in a city area which have common cycles. We analyse the network coordination problem and given splits for each phase, determine offsets for all signals.
