Monitoring traffic operations in a detailed manner and at the network level is a fundamental component in optimal traffic systems control. Especially in the case of urban signalized networks, accurate and reliable systems monitoring is essential for

In this paper, an online regret based dial-a-ride (OR-DARP) algorithm is introduced and its performance evaluated on an actual demand responsive transit (DRT) system. The innovative part of the algorithm is the design of the optimization engine. A si

The objective of this study is to investigate if it is possible to reduce the operational cost of an online Demand Responsive Transportation System (DRT) by using probabilistic trip demands while leaving the optimization algorithm intact. The idea is

Evacuations are massive operations that create heavy travel demand on road networks some of which are experiencing major congestions even with regular traffic demand. Congestion in traffic networks during evacuations, can be eased either by supply or

Label setting techniques are all based on Dijkstra’s condition of always scanning the node with the minimum label, which guarantees that each node will be scanned exactly once; while this condition is sufficient it is not necessary. In this paper,

This paper is concerned with the system optimum-dynamic traffic assignment (SO-DTA) problem when the time-dependent demands are random variables with known probability distributions. The model is a stochastic extension of a deterministic linear progr

This paper introduces a dynamic network design problem model that can be used to compute continuous network improvements. The model assumes system optimum traffic flow conditions and time-dependent demand. A linear programming formulation is introduc

This paper introduces a polynomial combinatorial optimization algorithm for the dynamic user optimal problem. The approach can efficiently solve single destination networks and can be potentially extended to heuristically solve multidestinational net

This paper is concerned with implementation challenges related to using dynamic traffic assignment on actual large urban networks. Such challenges include the manipulation of network and demand data, the modeling of turning movements, the efficient c
