Vehicle-Pedestrian Interaction in SUMO and Unity3D

Abstract

Road fatalities that involve Vulnerable Road Users (VRU) outnumber in some countries and regions ones that involve vehicular drivers and passengers. As most vulnerable road user fatalities happen in urban areas, where the traffic conditions are more demanding and an increased pedestrian interaction can result in unpredictable scenarios, it is imperative to study solutions to reduce the high rate of accidents in which pedestrians are involved. To this end, we present in this paper a simulation framework that provides a framework to generate a variety of pedestrian demands to simulate vehicle-pedestrian interaction and vice versa. A Transmission Control Protocol (TCP) connection combines the game engine Unity 3D with the Simulation of Urban Mobility (SUMO) open source traffic simulator. After creating the 2D scenario SUMO was connected with Unity 3D by using the Traffic Control Interface (TraCI) Protocol and TraCI as a Service (TraaS) library. The motion in Unity took place after instantiating the pedestrians retrieved from SUMO. The system was evaluated by detecting and visualizing pedestrians and vehicles that were within a specific range.
