Observation and experiment of driving behaviors near speed humps and speed tablesJiho Yeo, Junhan Cho, Hoyoung Lee, Dong-Kyu Kim, Kitae Jang
ObjectiveInvestigate the effects of speed humps and tables on vehicle speeds under high-speed conditionsAssess human factors that affect speed-reduction patterns of driversData & Study siteEast pangyo Street in the city of pangyoBoth observation & experiment were conductedObservation With Radar detecting vehicle speeds every 75ms Collect speed profiles of passing vehicleExperiment Evaluate drivers’ perception & reaction

Slide2ResultConclusionClosely-installed devices effectively stabilize the vehicle speedsDrivers with high speed tend to change the speed more abruptly
These abrupt behaviors were prominent in isolated speed control devices Suggesting the need of consecutive speed control devices Drivers started to reduce their speeds before fixating eyes on the devices Fixating times doesn’t differ by physical surroundings & type of devicesCompare speed profiles using paired t-testAnalyze eye fixation & drivers’ reaction
