V2X Vehicular Communications System


Road accidents represent a serious social problem and a leading cause of people death and disability in many countries. More than 93 people have been killed each day on average on the U.S. roads in 2010, plus an amount of $871 Billion of economic and societal impact on U.S. citizens due to vehicle crashes. Hence, we develop novel wireless solutions to enhance road safety by reliably and timely exchanging safety messages among vehicles. Each safety message carries vehicle status information, such as speed, acceleration, brake status, etc., which allows for the implementation of many advanced road safety applications.

Description of the invention

The global smart transportation market was valued at US$ 43.47 Billion in 2013, and is expected to witness a rapid growth during the period from 2013-2018, to reach US$ 100.92 Billion by 2018. Specifically, for vehicular networking, the market growth is driven mainly by the high number of traffic accidents and its severe socioeconomic impacts, which have increased the need for a safer transportation system; and the government initiatives around the world toward mandating vehicular networking technologies 

Our wireless technology was recently awarded the second prize in the highly competitive Innovation Challenge organized by Valeo, among 969 participating teams from 55 countries. Our research on vehicular networking is supported by GM and has been granted several Best Paper Awards from highly recognized international conferences.


Quality-of-service support for high priority road safety applications:

  • Reliable broadcast of safety messages
  • Suitable delivery delay of the broadcast safety messages by vehicles and road-side units
