DRIVE C2X
Overview
Intelligent Traffic Lights (iTLIs or iVRIs)Within the Partnership Talking Traffic, a new generation of intelligent traffic light installations (iTLIs) has been developed, that know which cars, cyclists or buses are approaching them. Every car of every marque and every navigation system and every smartphone can be linked to every intelligent traffic light installation from every supplier. All the technology and interfaces comply with international ETSI standards (SPaT, MAP, CAM, SRM, SSM, DENM). This fact makes it possible to harmonise traffic flows more efficiently, via dynamic traffic light controls. iTLIs are also able to give ‘priority’ to certain traffic flows above other, for example cyclists, emergency services or public transport. The traffic light can also automatically ensure that a convoy of trucks can pass through green in one light change. This reduces stopping and starting thereby saving time, fuel and CO2 emissions, as well as money. It has been calculated that society overspends to the tune of 90 million euro a year, because not all traffic lights are adjusted often enough. New iTLIs constantly adjust the settings, automatically. In other words, the investment pays for itself very quickly.

Inputs
​
On Board Unit (OBU)
​
-
OBU as per vehicle manufacturer and ITS sector
-
Vehicles are provided by the OEMs and other project partners and are equipped with both communication (CCU) and application units (AU), the CCU is equipped with a Linux operating system and a WLAN antenna, as well as a CAN adapter; the AU is currently running a Microsoft Windows version
​
Road Side Unit (RSU)
​
-
Variable message signs or traffic lights integrated into the ad-hoc communication network (RSUs)
Data Processing Hub
​
-
The traffic management center controlling roadside infrastructure, a fleet management center, etc.
-
Vehicles or roadside infrastructure may send information to the central component, and the latter may, in turn, send information to vehicles or roadside infrastructure

Achievements & Benefits
-
The main benefit is that Drivers react to information and warning signals.
-
In this project Eight different cooperative functions successfully tested with 750 drivers in Finland, France, Germany, Italy, the Netherland, Spain and Sweden.
-
More than 200 vehicles drove more than 1.5 million km, faultless performance of system and functions under all relevant traffic and climate conditions.
-
Due to the safety impact of this project the comfort level of user has been increased.
-
Nine out of ten test users highly welcome the DRIVE C2X system, and that they are willing to use it if it is available on their vehicles.
-
The viability of the Business model that is used for the testing is questionable and needs some improvements.
-
The Project that is relied on sensing vehicle movement through road side infrastructure is to issue the warning signals because the new vehicles that are in use already have on board safety warning systems along with aid of V2X communication.
-
IVS Speed limit and Weather warning showed most potential to decrease fatalities: o Assuming a 100% penetration rate, IVS speed limit that provides continuous information would reduce on average 23% in fatalities and 13% in injuries. Weather Warning would lead to 6% less fatalities and 5% less injuries.
-
Road works warning would decrease fatalities by 3%, Emergency brake light warning and Traffic jam ahead warning by 2%. These functions would decrease injuries by 2% assuming all vehicles are equipped.
