Queue Management Project: Testing Strategies Using the Model.

This Working Paper is one of a series representing work under an SERC grant on queue management strategies for urban traffic control systems whose objectives are:- (i)to generalise the strategies developed in an earlier study of queue management, (ii)to develop a computer graphics based representation of queue propagation and management; (iii)to test the strategies' applicability and performance in UK networks; (iv)to investigate their incorporation into standard signal optimisation programs. Clark (1991) in WP 343 describes the graphics model developed at ITS as a queue-management tool for traffic engineers. In order to calibrate the model, and later implement a suitable queue management strategy recommended by the model, a small oversaturated urban traffic network was required. Six possible sites in the West Yorkshire region were suggested by HETS (West Yorkshire Highway Engineering and Technical Services) for consideration. Wellington Street in Leeds city centre was identified as the most suitable being a linked series of three signalized junctions where blocking-back was commonplace, parking violations were minimal and an adequate filming position was available.
