The goal of the project is to develop solutions that provide context-sensitive, predictive and individual support to drivers of passenger cars and commercial vehicles in city traffic. Within this context, DLR is working on a specific aspect of car2x communications. The goal is to devise an instruction format that enables traffic lights to communicate with the cars regardless of make, type or manufacturer. For instance, future traffic lights can pass on information to the cars in the environment; the information could be generated by a 'smart guiding pylone' which could be placed by the police in the case of an accident or a construction site. This smart guiding pylone would connect wirelessly to the traffic light to inform them about the traffic obstruction. The traffic light in turn would send the message to the vehicles in the vicinity, alerting them about the situation and thus contributing to prevent accidents and, if applicable, recommending a deviation.
Another data type contains the remaining time of the red or green phase. Drivers can use this information, to reduce or increase their speed accordingly - in future systems, this adjustment could be done automatically.
