Having the advantages such as non-destructivity and high precision, the ground penetrating radar (GPR) has been widely used in the quality control of highway engineering. But the post processing of the GPR signal still needs to be further studied. In this paper, the author applies the least square deconvolution to ground penetrating radar signal post-processing, presents its relevant theory and method,...
In order to effectively guarantee the pedestrian safety, coordinate relations between the image pixels and actual position of road is founded based on zebra crossing feature. A method which detects pedestrian and predicts the position of pedestrian in real-time for use is presented based on Kalman predictor. By this method, pedestrian-vehicle collision point can be prejudged and pedestrian information...
Signalized intersections with weaving segment upstream are very common on urban roads. Weaving segment determines the arrival rate of the approach, and the operational condition of itself is affected by the approach queue accumulated at the same time. According to the character of arrival and departure of vehicles, the impact of weaving segment on the signalized intersections capacity is analyzed...
