The signal control system of the congestion length is considered in
the urban road network; in this control system, the reference input,
control input and output are given by the permitted congestion length
IJ,j,m,k) , the three signal control parameter and the congestion
length respectively. In this way, the signal control system of the
congestion length is synthesized using the feedback control both at
each signalized intersection and in a two-way urban road network.
The purpose of the signal control system of two-way urban road
networks is to find such control input that it makes the following
