Performance of Traffic Networks: A Mosaic of Measures

This thesis focuses on performance of traffic networks. The author begins by reviewing various performance related issues at both a link level and at a network level. The study considers the existing body of knowledge in measuring the performance of links and networks, investigates the notion of network performance, and explores the features and characteristics of road networks under various traffic loads. Topics include previous work by Lighthill, Witham, and Richards (LWR); other models; stochastic link performance; short-term prediction of network state; the features of road networks and measures for network reliability; and assignment efficiency, including entropy-maximization and network management. The author concludes that three main areas are required to establish an adequate measure for network performance: a technique to collate the results of breakdown probability over a network based on results of probability of breakdown on individual links; the computation of the vulnerability of a network to cascading breakdown; and the application of entropy methods to estimate the efficiency of the current assignment and also to compute the optimal assignment. Three appendices cover transport equilibrium, the notion of "stable and robust" as applied to systems, and the properties of Shannon's entropy.
