PROGRESSIVE SIGNAL SYSTEM IN A NETWORK OF ARTERIAL STREETS (ABRIDGMENT)
TK Datta, WC Taylor, DM Litvin - 1976 - trid.trb.org
Computer-aided systems to coordinate traffic signals on urban roadways have been
developed to achieve a smooth flow of traffic uninterrupted by the red phase of the signals. A
new model, the traffic signal optimization model (TRASOM), has been developed that
considers the three basic traffic variables: speed V, volume Q, and density, K. The model
allows different road segments to have different QDV relationships because traffic flow
depends not only on the geometrics of the road but also on the environment and traffic …

The" TRASOM" system described optimizes traffic flow through a network of arterial streets
based on actual intersection demand and traffic handling capacity of roadways. The data
requirements are reasonable compared to existing network optimization models and
consideration of the speed volume function for all critical locations in a network increases
the probability of success of its output timing plans when implemented in the field.
