Multiregime Approach for Microscopic Traffic Simulation

Abstract

The purpose of this paper is to explore various traffic modeling aspects and theories that may overcome some of the limitations in existing microscopic simulation models. A multiregime microscopic traffic simulation approach has been formulated featuring realistic and comprehensive carfollowing and lane-changing logic. A prototype implementation of the multiregime approach was developed in C++ and extensively tested. The multiregime simulation results demonstrate the efficiency and validity of the proposed models for a broad range of traffic scenarios. The test and validation results indicate that the model and program outperformed traditional methods and other existing traffic simulation programs. The validity and efficiency of the model is attributed to the fact that the regimes were added to the model incrementally to reflect increasing agreement with real-world traffic flow. The techniques and corresponding models will be used to improve existing microscopic traffic simulation models and programs.

Lane-changing behavior on urban streets: A focus group-based study

“…Each of these is further modeled in a sequence of three steps: 1) lane-changing necessity checking, 2) target lane choice and 3) gap acceptance decision. Based on a review of the existing lane-changing algorithms, the two most popular ones are rulebased models (Gipps, 1986;Hidas, 2005;Zhang et al, 1998) and discrete choice-based (DCB) models (Ahmed, 1999;Choudhury, 2007;Toledo et al, 2003;Yang and Koutsopoulos, 1996). Both may be implemented as a lane-changing module in micro-simulation.…”

Realistic mobility simulation of urban mesh networks

“…People will certainly not overtake slower walkers if there is no room (e.g., if the other lanes are full). Even if there is room, pedestrians (as well as vehicles) might not pass out of choice and select to slow down and follow the node ahead [34]. Such decisions lead to platooning.…”

Modeling of Car‐Following Required Safe Distance Based on Molecular Dynamics

“…Peter Hides carried out further research on microscopic behavior of urban traffic flow and preliminarily established car-following models for urban traffic flow based on expectation distance [9]. Zhang et al gave deep research on psychological and physical reaction mechanism of the driver and presented multiregime model based on the driver's psychological reaction [10]. At present, the car-following model based on safe distance has been widely applied to microscopic simulation of road traffic, which is one of the hot research topics in the field of traffic engineering [11,12].…”
