Urban Transport Corridor Mesoscopic Simulation
نویسنده
چکیده
Currently different categories of traffic analysis tools exist. Among them simulation models can be marked as one of the most powerful approach to do traffic analysis researches. In classical literature simulation models are divided on macroscopic, mesoscopic and microscopic models. Microscopic and macroscopic modelling are well known and widely used, but both of them have disadvantages and limitations, which make them in some conditions hard to apply. The term " mesoscopic modelling " itself, is interpreted by different scientists in different ways. In general under mesoscopic traffic flow models should be understood as models where traffic flow is described with high level of detail, but at the same time flow behaviour and flows interaction are presented at a low level of description. The proposed earlier new simulation approach called by authors " mesoscopic simulation " was applied for traffic flow simulation. The main goal of this paper is to present an example of application of discrete rate approach of the ExtendSim simulation software for urban transport corridor simulation. The discrete rate approach fully covers ideas of mesoscopic simulation. The literature survey showed that mainly discrete rate approach is used in logistics, but not in transport area. So the tasks of the paper are to present main techniques of model implementation using discrete rate approach and to apply this approach for urban transport corridor simulation.

Mesoscopic Simulation Concept for Transport Corridors
A transport corridor is a (generally linear) tract of land in which at least one main line is provided for transport, whether it is a road, rail or canal facility. In this paper under transport corridor we will understand a road which connects two geographical points. The need of research and analysis of the transport corridors is mainly connected with wish to locate bottlenecks of the corridor...
متن کاملA Simulation-based Dynamic Traffic Assignment Model with Combined Modes
This paper presents a dynamic traffic assignment (DTA) model for urban multi-modal transportation network by constructing a mesoscopic simulation model. Several traffic means such as private car, subway, bus and bicycle are considered in the network. The mesoscopic simulator consists of a mesoscopic supply simulator based on MesoTS model and a time-dependent demand simulator. The mode choice is...

This paper proposes a framework for quantifying the macroscopic impacts of delivery goods made by double-parked vehicles in urban arterial using microscopic simulation. It is applied to a real urban corridor: the Lafayette Avenue in Lyon (France). The framework combines traffic states with stochastic and microscopic freight demand generation model, i.e. the delivery movements and the delivery d...
متن کاملIncorporating Active Transport of Cellular Cargo in Stochastic Mesoscopic Models of Living Cells
We propose a new multiscale method to incorporate active transport of cargo particles in biological cells in stochastic, mesoscopic models of reaction-transport processes. Given a discretization of the computational domain, we find stochastic, convective mesoscopic molecular fluxes over the edges or facets of the subvolumes and relate the process to a corresponding first order finite volume dis...

(Originally and inspirationally entitled, 'A hybrid geocomputation model for operational land-use and transport simulation.) ABSTRACT There are indications that the current generation of simulation models in practical, operational uses has reached the limits of its usefulness under existing specifications. The relative stasis in operational urban modeling contrasts with simulation efforts in ot...
