A new floating car data technology in Hefei has been developed that provides real-time traffic information within Hefei's two ring road. It is based on the collection of localisation data, speed, direction of travel and time information from GPS in vehicles that are being driven. The scope of the project is to development and creation of a Web-based data mart for the collection of FCD. The aim of...
This paper proposes an automated steering control system for passenger cars. The control strategy used is a look-down reference system which uses a sensor at the front bumper to measure the lateral displacement and a GPS to measure the heading orientation. Firstly, the road curvature estimator is designed based on the steering angle. Secondly, the steering angles can be estimated by using the sensor...
One opportunity to manage the increase of freight transportation and to optimize utilization of motorway capacities is the concept of truck platoons. With the aid of Advanced Driver Assistance Systems, trucks are electronically coupled keeping very short gaps (approx. 10 meters) to form truck platoons on motorways. This contributes to optimization of traffic flow and reduction of fuel consumption...
Vision difference or inattention to the traffic condition often causes the unnecessary traffic accidents while driving. Therefore, this study is to fast detect both the preceding vehicle and lane marking at the least response time 0.5972 seconds. After coordinate transformation converts image plane coordinates of the preceding vehicle to GPS coordinates, the headway between cars is obtained to assist...
In this paper, the MEMS-based IMU (Inertial Measurement Unit) was used in a fusion navigation system comprising a MEMS-based IMU and a GPS device with the map database. The attitude angle of a vehicle at a specific location is detected by the MEMS-based IMU and compared with the identifying information from the map database for judging whether the vehicle is on a correct route or not. The fusion navigation...
