DENSE NETWORK TRAFFIC MODELS, TRAVEL TIME RELIABILITY AND TRAFFIC MANAGEMENT. Ii: APPLICATION TO NETWORK RELIABILITY

摘要

This paper is the second of a pair of papers discussing two main themes concerning dense network modelling. These themes are :(1) the changing nature of traffic management technology and the underlying objectives behind traffic management practice, and (2) the use of measures of network reliability in models, especially as an element of the evaluation of alternative network configurations. This paper develops and applies the second theme, the use of network reliability concepts in the evaluation of traffic networks, through consideration of variations in travel times, distinction between local street and arterial road networks, and the definition and application of a set of reliability indices that may be used to study different trip movements in a network. It indicates how these indices may be used in appraising different traffic management plans for a dense network of local streets and arterial roads, using a case study application.
