An integrated approach for road, transit design in a city logistic plan: a case study

Abstract

In this paper, an integrated network and transit route design problem is analysed. A two-step design approach is proposed: first a trial transit route is designed using a greedy algorithm, second the road network is optimized taking into account, in the objective function, also of the route cost for freight. At the end of procedure, also the vehicle routing problem for city logistic distribution is designed using optimized road network and the reserved lanes for bus. The whole problem is formulated as a continuous-discrete problem, to consider both the topology and the link capacity.

A before–after analysis for the design problem on an urban road network

“…Poorzahedy and Ro hani [30] propose several hybrid algorithms considering rigid demand and the construction of new lanes. Russo and Vitetta [29] propose a three-step method for the solution selection (topological similarity, cluster analysis, solution selection procedures are applied in comparison with the transit design [34]. The models and the procedures and for simulation and design system is applied also in evacuation in urban area [35,36]) [33] In this paper, a formulation of the NDP is proposed and some algorithms to solve it are discussed.…”
