| Summary | Due to global warming, more countries have been promoting green transportation such as bicycles. In order to increase the use of bicycles as a transportation method, it is necessary to create a safe environment for bicyclists. Understanding the interaction between motorized vehicles, pedestrians, and bicycles in the current traffic environment will allow for improvements to traffic safety. Improvements in traffic conditions will allow the carbon reduction and safety benefits of cycling to become more apparent.
The use of digital image recording and motion sensor technology to observe driving behavior is a recent trend in safety research. This year’s research, a naturalistic observation of cycling behaviors, made use of digital video cameras and motion sensors (GPS, ultrasound technology, proximity switches, accelerometers, electronic compasses and gyroscopes) as measurement equipment to observe cycling behaviors and vehicle interactions at intersections and other fixed points. This research used digital imagining to observe steering angles, longitudinal and lateral acceleration, and the space on the left and right sides of traffic as a parameter with which to filter data and create a database to sort out abnormal data. This behavioral data set-up and analysis is based on practical data measurements and images. In addition, this research processed images of vehicle and pedestrian using two sets of video cameras to clearly observe traffic situations and behaviors at intersections. This study also developed an image-processing program to calculate the distance between bicycles, road markings, and other vehicles. |
