Traffic simulation. Traffic simulation or the simulation of transportation systems is the mathematical modeling of transportation systems (e.g., freeway junctions, arterial routes, roundabouts, downtown grid systems, etc.) through the application of computer software to better help plan, design, and operate transportation systems.

Simulation of Urban MObility (Eclipse SUMO or simply SUMO) is an open source, portable, microscopic and continuous multi-modal traffic simulation package designed to handle large networks. SUMO is developed by the German Aerospace Center and community users. It has been freely available as open-source since 2001, and since 2017 it is an Eclipse ...
PTV Vissim is a microscopic multi-modal traffic flow simulation software package developed by PTV Planung Transport Verkehr AG in Karlsruhe, Germany. It was first developed in 1992. The name is derived from " Verkehr In Städten - SIMulationsmodell " (German for "Traffic in cities - simulation model").
Urban traffic modeling and analysis is part of the advanced traffic intelligent management technologies that has become a crucial sector of Traffic management and control. Its main purpose is to predict congestion states of a specific urban transport network and propose improvements in the traffic network. Researches rely on three different ...
The selection of simulation as a modelling tool is usually because it is less restrictive. Other modelling techniques may impose material mathematical restrictions on the process, and also require multiple intrinsic assumptions to be made. [2] Network traffic simulation usually follows the following four steps: [1] [2]
TRANSYT-7F is a traffic simulation and signal timing optimization program. The primary application of TRANSYT-7F is signal timing design and optimization. TRANSYT-7F features genetic algorithm optimization of cycle length, phasing sequence, splits, and offsets. TRANSYT-7F combines a detailed optimization process (including genetic algorithm ...
Traffic flow. In transportation engineering, traffic flow is the study of interactions between travellers (including pedestrians, cyclists, drivers, and their vehicles) and infrastructure (including highways, signage, and traffic control devices), with the aim of understanding and developing an optimal transport network with efficient movement ...
Intelligent driver model. In traffic flow modeling, the intelligent driver model (IDM) is a time-continuous car-following model for the simulation of freeway and urban traffic. It was developed by Treiber, Hennecke and Helbing in 2000 to improve upon results provided with other "intelligent" driver models such as Gipps' model, which loses ...
