Comparative Analysis of Simulation of Multi-Lane-Changing Models Under SUMO Platform

Vehicular Ad-hoc Networks (VANETs) are ubiquitous networks in which vehicles communicate with nearby vehicles and infrastructure nodes (such as roadside units) [1]. VANETs are an essential component of smart city environments, contributing to enhanced safety, quality of life, and security for vehicle users [2]. Currently, research on vehicular network communication protocols and applications mainly relies on simulation platforms. The performance of embedded vehicular mobility models within these platforms plays a crucial role in the analysis and study of protocols [3]. This paper first provides a detailed description of three vehicular lane-changing models under the Simulation of Urban Mobility (SUMO) platform. Next, two different simulation platforms are set up. Finally, using urban road traffic environments and varying simulation scenarios, the paper compares and analyzes three metrics—vehicle density, average vehicle speed, and average vehicle delay—under different lane-changing models. The experimental results show that the LC2013 model demonstrates the best performance.
