One of the most important technological factors in realising intelligent transport systems (ITS) is the further development of external sensing, which has recently witnessed considerably improvements and made significant contributions to enhanced driving safety. The featured technologies include an adaptive cruise control system that utilises a radar sensor and allows a vehicle to follow the leading vehicle. Due to reasons affecting practical application, the technology is still limited to highway use. It is anticipated that this will be expanded to include ordinary road traffic. However, further research will be required before the external sensing technology can be applied to the more complex circumstances existent in urban traffic. This paper reports on the results of the experimental application of a vision sensor. Also reported is an evaluation of the ability to detect other traffic users, namely other vehicles and pedestrians, that the sensor is able to offer. The most important evaluation criterion was the detection of a vehicle cutting-in under urban traffic conditions featuring a complex interaction of traffic users. The cutting-in detection was achieved through combining the leading vehicle location information and lane detection, which were enabled by the use of a recognition algorithm. Also reported is the result of the detection capability test of the sensor used. For the covering abstract see ITRD E114174.
