Broadcast news: Motorola MOTODRIVE System Engineering's John Buchalo on the creation of the company's new 5.9 GHz-compliant architecture

摘要

The concept of Vehicle Infrastructure Integration (VII) has been around in one form or another for nearly 15 years. Early on, the US Department of Transportation (USDOT) theorised that applications such as intersection collision avoidance and automatic crash and incident detection and response could be best accomplished through vehicle-to-infrastructure and vehicle-to-vehicle communication. In 1999, the FCC allocated the 5.9 GHz band for Dedicated Short Range Communications (DSRC) between vehicles to support ITS applications. The USDOT later envisioned a DSRC-based Onboard Unit (OBU) in every vehicle, working in conjunction with a substantial infrastructure of DSRC-based Roadside Units (RSUs). Information would then be transmitted between OBUs and RSUs and between OBUs.
