The Interaction Between Signal Control and Traffic Assignment: An Introduction.

Traffic assignment and signal control are generally considered separately. Proper recognition of the interaction that exist between assignment and signal control introduces a number of theoretical and computational complexities; on the other hand considerable network improvements can be achieved. This report introduces the problem of interaction between signal control and traffic assignment, reviews related issues and previous work. It discusses signal control as a network design problem, and it makes a case for the iterative assignment control procedure for its approximate solution.
