IEEE802.11p ahead of LTE-V2V for safety applications
Car-to-car communication is attracting significant attention as it promises to drastically reduce road fatalities, improve mobility and enable a high-level of vehicle automation
Intelligent transport system (ITS) technology allows cars to communicate with each other as well as with intelligent traffic infrastructures. The IEEE802.11p Wireless Access in Vehicular Environments (WAVE) standard allows cars to securely connect to each other as well as to infrastructure, helping to reduce road accidents, saving people’s lives, reducing CO2 emissions and improving traffic flow.
NXP RoadLINK technology exchanges messages reliably across an extended range at high speed, cutting ‘time to react’ and communicating potential hazards and safety-critical scenarios significantly faster than conventional applications.
The leader in V2X trials, RoadLINK offers the robust and secure foundation for creating ITS all around the world. Supporting both DSRC (IEEE 802.11p) and Wi-Fi (802.11abgn) wireless standards, RoadLINK can upload and access data via home Wi-Fi and hotspot connections.
Technological innovations often lead to changes in our driving styles, whether it’s start-stop technology, parking assist or blind-spot detection. Fast becoming the proven ITS technology of choice, RoadLINK V2V and V2I implementations will make driving safer, smoother, less frustrating and more eco-friendly, as well as open up fruitful commercial services.
The robust RoadLINK platform supports accepted standards (such as IEEE802.11p) and various OEM configurations, and offers a high level of security. Flexible and scalable, it enables a diverse range of applications, from traffic control to commercial use-cases such as toll collection and driver services.
Safety is the most important benefit of V2V systems. By allowing vehicles to reliably interact with each other, driving safety will improve dramatically. V2V communication, even at high-speeds or with no line of sight between vehicles), ensures each vehicle can rapidly generate warnings about potential hazards, helping drivers avoid accidents. Also, in an autonomous system, the V2V system can even respond automatically to changing driving conditions.
Local news broadcasts are an invaluable aid to avoiding traffic hold-ups. However, V2I systems can ensure drivers receive warnings about traffic blockages much more quickly, and only those affecting the driver’s route. Moreover, V2I systems using RoadLINK can form part of a highly effective complete traffic management network that ultimately helps reduce fuel consumption and greenhouse gas emissions.
