An IMU-based traffic and road condition monitoring system

摘要

This paper presents a new type of wireless platform designed for real-time traffic estimation and road surface monitoring. The sensor platform is built around a 32-bit ARM Cortex M4 micro-controller and a LSM9DS0 Inertial Measurement Unit module. This platform is mainly designed for probe vehicles and can be easily installed in a vehicle equipped with a USB charger. The hardware architecture design and software programming system of the proposed platform are introduced as well as its cost evaluation from the first generation to the third generation. The article then demonstrates some applications of such a platform in smart cities, including trajectory estimation and road condition monitoring. All design files have been uploaded and shared in an open science framework, and can be accessed fromhttps://osf.io/524y9/?view_only=85859a345a7b429fbb8fe194966daa5b.
