In this note, a simple network equilibrium based approach for estimating a trip matrix using link traffic count data is proposed. In essence a combined distribution and assignment model is formulated in which the link flow data serve to furnish an estimate for the sum of the integrals of the...

This paper explores the relationship between heavy vehicle traffic and network congestion by explicitly modelling the different behavioral characteristics of light and heavy vehicle flows. Two cases are studied, namely travel times on a road segment and delay at a priority intersection....

This note shows how the maximum entropy trip matrix estimation procedure incorporated in ME2 as proposed by Willumsen (Van Zuylen and Willumsen, 1980) can be combined with a user optimal assignment model such as SATURN (Van Vliet, 1982) into a single mathematical problem. The resulting problem...

In this paper, correspondences are drawn between two game theory models (Nash noncooperative and Stackelberg games) and some problems in transportation systems modelling. An example of each is described in detail, namely the problem of carriers competing for intercity passenger travel and the...

This paper examines different formulations for estimating trip matrices on congested networks from link traffic count data. It is shown that several existing approaches can be expected to produce the same results when observed counts constitute a user optimal link flow pattern. This has...

In this paper a probabilistic model developed by Cowan describing flow characteristics on a single lane of traffic is adopted to produce link travel time/flow relationships appropriate for use on some links in traffic assignment. The resulting model parameters relate directly to the mean and...

An approach to intersection delay analysis appropriate for representing turning movement delay at priority intersections in traffic assignment models is presented. The formulae are derived as an approximation to a dynamic queueing model by extending an approach adopted at the Transport and Road...

A new price formulation of the spatial price equilibrium model for congested networks is presented which allows for situations in which equilibrium between producers and consumers within a region may not be achieved. It also leads to a variational inequality in link flow without requiring that...

This paper investigates the lane choice problem as it affects intersection delay analysis and traffic assignment. A model framework is proposed and solution properties of the lane choice and assignment problems are examined.
