CrIS UTC’s Stanley Chien, from the Transportation Active Safety Institute (TASI) at Indiana University-Purdue University Indianapolis (IUPUI), presented a paper at the Intelligent Transportation Systems Conference (ITSC14) in Qingdao, China. Chien’s paper “Obtain a Simulation Model of a Pedestrian Collision Imminent Braking System Based on the Vehicle Testing Data” was written with professor Yaobin Chen, TASI, and Bo Tang, IUPUI graduate student.

Forward pedestrian collision imminent braking (CIB) systems have proven to be of great significance in improving road safety and protecting pedestrians. Since pedestrian CIB technology is not mature, the performance of different pedestrian CIB systems varies significantly. Therefore, the simulation of a CIB system needs to be vehicle specific. The CIB simulation can be based on the component sensor parameters and decision making rules. Since these parameters and decision rules for on the market vehicles are not available outside of vehicle manufactures, it is difficult for the general research communities to develop a good CIB simulation model based on this approach. To solve this problem, this study presents a new method for developing a pedestrian CIB simulation model using pedestrian CIB testing data. The implementation was in the software PreScan. The simulation results demonstrate that a pedestrian CIB simulation model developed using this methodology could reflect the behavior of a real vehicle equipped with pedestrian CIB system.

The conference took place October 8-11, 2014, and included a variety of presentations, tutorials, short courses and workshops. A copy of the paper can be found on the CrIS UTC website at www.citr.osu.edu/CrIS
