A system of models for signal setting design of a signalized road network in evacuation conditions

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.

A statistical approach to analyze user behaviour in road evacuation

“…Models simulating the interaction of demand and supply by Vitetta et al [16][17][18], Marciano et al [19,20]; for this theme we recall also Russo and Vitetta [21].…”

Within-day traffic assignment and signal setting in road evacuation: a procedure with explicit path enumeration

“…Therefore, the solutions are compared and evaluated in terms of the values of the objective function. The following section analytically describes the solution simulation procedure, while a description of the solution generation procedure can be found in [12,13].…”

“…In the sphere of the last research line, we developed a framework for signal setting design of road intersections with endogenous estimation of path fl ows [12]. The framework has two main components: (i) an optimization procedure for signal setting design [13] and (ii) a within-day simulation procedure to capture the effects of signal setting modifi cation on path choice behaviour presented in this paper.…”

“…The general objective is risk reduction in urban areas in terms of exposure [1]. Specifi c research lines concern travel demand models [2][3][4], planning processes and guidelines [5][6][7], route design for emergency vehicles [8][9][10], transport supply and travel demand-supply interaction [11].In the sphere of the last research line, we developed a framework for signal setting design of road intersections with endogenous estimation of path fl ows [12].

An approach to designing vehicle routes in evacuation conditions

“…The objective of the SICURO project is the development of models and guidelines for evacuation demand simulation [7], supply and demand-supply interaction simulation [8], supporting path design for emergency vehicles [9], and supporting urban transport planning in emergency conditions [10]. In a recent update [11,12] the authors of this papers proposed an approach to simulate the evacuation demand in emergency conditions using dynamic models; in [13] and [14] a system of models and procedures is proposed for signal setting design in evacuation conditions; in [15] and [16] two classes of methods to compare evacuation plans are proposed.…”
