Models and algorithms for road network design: a review and some new developments
The Network Design Problem (NDP) has long been recognized to be one of the most difficult and challenging problems in transport. In the past two decades, we have witnessed the development of a vast,Expand

Optimal traffic counting locations for origin–destination matrix estimation
There has been substantial interest in development and application of methodology for estimating origin-destination (O-D) trip matrices from traffic counts. Generally, the quality of an estimated O-DExpand

Capacity reliability of a road network: an assessment methodology and numerical results
TLDR
This paper extends the capacity reliability analysis by providing a comprehensive methodology, which combines reliability and uncertainty analysis, network equilibrium models, sensitivity analysis of equilibrium network flow and expected performance measure, as well as Monte Carlo methods to assess the performance of a degradable road network.

Heuristic algorithms for the bilevel origin-destination matrix estimation problem
Recently, a bilevel programming approach has been used for estimation of origin-destination (O-D) matrix in congested networks. This approach integrates the conventional generalized least squaresExpand

A NETWORK MODEL OF URBAN TAXI SERVICES
TLDR
A network model is developed to describe how vacant and occupied taxis cruise in a road network to search for customers and provide transportation services, and offers some policy-relevant results for decision making. Expand

The multi-class, multi-criteria traffic network equilibrium and systems optimum problem
TLDR
It is well known that in the standard traffic network equilibrium model with a single value of time (VOT) for all users, a so-called marginal-cost toll can drive a user equilibrium flow pattern to a system optimum when the objective function is measured by either money or time units. Expand

An equivalent continuously differentiable model and a locally convergent algorithm for the continuous network design problem
The continuous network design problem (CNDP) is characterized by a bilevel programming model and recognized to be one of the most difficult and challenging problems in transportation. The mainExpand

Multiple equilibrium behaviors and advanced traveler information systems with endogenous market penetration
We consider a specific advanced traveler information system (ATIS) whose objective is to reduce drivers' time uncertainty with recurrent network congestion through provision of traffic information toExpand
