This chapter reports on the results of applying the interregional model to study different pricing policies that reflect the external costs of the various transport services in Ireland. As Ireland is an island with no through traffic, the 1-country version of the model was used to calculate optimal policies.

One of the essential aspects of strategic traffic management is to determine the modifications which need to be made in the traffic system in order to improve its long-term functionality. The functionality of a traffic network is typically expressed in terms of traffic flows and functions thereof. The traffic management process is often based on repeated scenario analyses. Using numerical examples, the authors of this chapter show how a proposed traffic management procedure can be applied to small- and medium-scale network scenarios. The authors highlight the order of the computations and illustrate the flexibility and shortcomings of the methodology. Examples show that the procedure can be guided such that approximate solutions to the management problem can be found in a reasonable computational time. The authors use management scenarios in the networks of Sioux Falls, South Dakota (United States), and Linkoping, Sweden. In a comparison between the two-stage procedure and the direct search procedure, the authors conclude that the direct search procedure has an advantage in finding feasible solutions for cases where the two-stage procedure, without guidance, does not find a solution. However, the two-stage procedure has the advantage that is can provide a rough solution to the traffic management problem much more quickly. This chapter is from a book of essays published in honor of David Boyce for his contributions to the fields of transportation modeling and regional science.

This chapter on a modified iterative scheme for the equilibrium traffic signal setting (ETSS) problem is one in a book of essays published in honor of David Boyce for his contributions to the fields of transportation modeling and regional science. In this chapter, the author begins by providing essential background on ETSS, including formally defining the problem and presenting a selective overview of the relevant literature. The author then discusses the motivation and the key features of a proposed approach to ETSS, and outlines the details of the modeling framework and solution algorithm. The author also presents and discusses the results of numerical experiments in which the proposed approach is implemented on a small test network, but using realistic link delay functions as descriptors of intersection performance. The author concludes that results obtained from the numerical tests are encouraging and suggest that the proposed approach to ETSS may represent a worthwhile step toward an improved description of the real-world evolution of network conditions ensuing from the interaction of route choice and traffic-responsive signal control.
