This paper describes the implementation of a framework for incorporating detailed models of intersection operation into a user-optimal route choice model. It is assumed that signal settings are flow-responsive: this yields a combined route choice-intersection control problem, which is formulated as a non-separable network equilibrium problem with asymmetric cost functions. Such cost functions represent delays incurred by vehicles at intersections under various types of control (signalized, major/minor priority and all-way stop), and are based on an approach to capacity analysis widely used in traffic engineering practice, namely the methodologies of the 1985 Highway Capacity Manual and related amendments. The combined route choice-control problem is solved using a diagonalization algorithm; computational tests carried out on a real network indicate that the algorithm converges to a user equilibrium consistent with the control policy, despite violation of the sufficient conditions for convergence.

Abstract

This paper describes the implementation of a framework for incorporating detailed models of intersection operation into a user-optimal route choice model. It is assumed that signal settings are flow-responsive: this yields a combined route choice-intersection control problem, which is formulated as a non-separable network equilibrium problem with asymmetric cost functions. Such cost functions represent delays incurred by vehicles at intersections under various types of control (signalized, major/minor priority and all-way stop), and are based on an approach to capacity analysis widely used in traffic engineering practice, namely the methodologies of the 1985 Highway Capacity Manual and related amendments. The combined route choice-control problem is solved using a diagonalization algorithm; computational tests carried out on a real network indicate that the algorithm converges to a user equilibrium consistent with the control policy, despite violation of the sufficient conditions for convergence.
