Abstract EN
To evaluate the effects of campus speed bumps on drivers’ speed and fixation distribution, a quasinaturalistic driving test was conducted on a Chinese campus.
Seven randomly selected drivers, wearing the Dikablis eye tracking devices, were required to drive an OPEL SUV passing the speed bumps.
The area close to the bump was divided into ten subsegments (15 m for each one).
The degree of fixation dispersion within each subsegment was defined as the distance from each subcenter to the whole fixation center.
All traffic data were recorded using mounted camera, and the trajectories were extracted in Matlab.
The speed and trajectory data was divided into two groups: the before group for bump-free case and the after group for a 5 cm bump case.
The observational before-after analysis shows statistical significance between the two cases.
The individual vehicular speed analysis reveals that bump reduces nearly 60% of vehicles’ speeds to a certain extent within the distance from 30 m upstream to 15 m downstream.
The drivers’ fixation points begin to disperse 30–45 m before they see the bump, and it falls back to normal level 15–30 m downstream of the bump.
These findings will help engineers install speed bumps at the most appropriate locations.
