| Abstract: | This study presents a design for the Lane Change Assistant (LCA). This Intelligent Transport System advises the driver whether it is safe to change lanes on a highway under current traffic conditions. This research focuses on how the LCA can give a reliable advice in practice, by considering several practical issues. The practical issues that are taken into account consist of changing circumstances, measurement uncertainties and model assumptions. A sensitivity study into these issues is performed, showing that a scenario where an emergency brake occurs under rainy weather conditions results in the most uncertain practical issues. The system compensates for the practical uncertainties by using certain extra safety distance. The communication to the driver consists of a spectrum of five LED lights, each guaranteeing a certan degree of safety, by applying a certain safety distance. In order to obtain these research results a micro simulation model is developed. This model is based on a lane change algorithm from the available literature and a vehicle following model. This powerful model relies on only a few negligible assumptions and has a probabilistic character to mimic the practice situation accurately. |
