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.
To understand simulation, it is important to understand the concept of system state, which is a set of variables that contains enough information to describe the evolution of the system over time. [3] System state can be either discrete or continuous. Traffic simulation models are classified according to discrete and continuous time, state, and ...
Used to determine the distance headway between a vehicle and its predecessor. One of the simplest model in this category is the Pipe's rule, the basic assumption of this model is "A good rule for following another vehicle at a safe distance is to allow yourself at least the length of a car between your vehicle and the vehicle ahead for every ten miles per hour (16.1 km/h) of speed at which you ...
Microscopic traffic flow models are a class of scientific models of vehicular traffic dynamics. In contrast, to macroscopic models , microscopic traffic flow models simulate single vehicle-driver units, so the dynamic variables of the models represent microscopic properties like the position and velocity of single vehicles.
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").
TransModeler is a based traffic simulation platform for doing wide-area traffic planning, traffic management, and emergency evacuation studies that is developed by Caliper Corporation. It can animate the behavior of multi-modal traffic systems to show the flow of vehicles , the operation of traffic signals , and the overall performance of the ...
TSIS-CORSIM is a microscopic traffic simulation software package for signal systems, highway systems, freeway systems, or combined signal, highway and freeway systems. CORSIM (CORridor SIMulation) consists of an integrated set of two microscopic simulation models that represent the entire traffic environment. NETSIM represents traffic on urban ...
