✦ Synopsis

In this paper, existing ®xed-point models for stochastic equilibrium trac assignment to transportation networks are extended to deal with the value of time distributed among users. This problem is relevant when transporation demand management measures aecting travelling monetary costs are to be evaluated. Analysis of existence and uniqueness of solutions is carried out, leading to mild assumptions about link cost-¯ow functions, path choice model, and value-of-time distribution. Some quite simple solution algorithms are also speci®ed and their convergence analysed. Results of some applications are also reported.

Turn-delays in intersections contribute signi®cantly to travel times and thus route choices in urban networks. However, turns are dicult to handle in trac assignment models due to the asymmetric Jacobian in the cost functions. The paper describes a model where turn delays have been included in the s
