Abstract
This paper proposes a system of models and procedures for the signal setting
design of signalized intersections in a road transport network with endogenous
estimation of origin-destination path flows. The system of models and
procedures is able to support signal setting design for a road transport network
both in ordinary and evacuation conditions.
Keywords: signal setting, design model, evacuation conditions.
1 Introduction
Nowadays signal control is considered an effective strategy to increase network
capacity and to mitigate congestion phenomena, as shown in several papers of
scientific literature.
Current signal setting design models and procedures do not provide solutions
that take into account users behaviour at path choice level in response to supply
system modifications; moreover, they are not conceived for the analysis of road
transport systems in evacuation conditions.
The paper presents a system of models and procedures for the signal setting
design of signalized intersections in a road transport network with endogenous
estimation of origin-destination path flows. The system of models and algorithms
is able to support signal setting design for a road transport network both in
ordinary and evacuation conditions.
The problem of signal setting design of signalized intersections in a road
network is defined as an optimization problem (design model) subjected to
equilibrium constraint; in other words, travel demand flows must be coherent
with travel times generated by signal setting parameters.
