A City Traffic Library

Abstract

Digital Product Simulation (DPS) created a library for the modeling of city traffic. This library is designed for the development and evaluation of control strategies, rendered possible when vehicles are able to communicate between each other and with their infrastructure. CityTraffic library allows for the implementation of control strategies by all of the players acting in an urban environment (e.g. located in vehicles, with a global server computing set points for the vehicles, or with a traffic management system setting speed limits and traffic light cycles). The library is divided in two parts, macroscopic traffic and microscopic traffic. Macroscopic components are used to describe road networks such as highways whereas microscopic components allow for modeling city traffic where interactions between vehicles and their environment are many. By using a City Traffic library, cities can decrease the number of traffic jams on their road network, and improve the overall impact of the traffic on the environment.
