Driving Behavior Survey Essay

Good Essays

Due to the existing need to explore driving behavior and safety at toll plazas, the objective of this study is to investigate the effect of applying multiple scenarios with various paths, signage, pavement markings, traffic condition, and extending auxiliary using driving simulator experiments. Drivers’ characteristics were collected from the questionnaire before each experiment. Four risky indicators including speed, standard deviation of speed, standard deviation of lane deviation, and acceleration noise were collected from each frame of the simulator experiments using MATLAB software to achieve the goal of this study. Four cameras with 60 HZ frequency were installed to record the experiments. Three cameras were pointed to the participants’ face, feet, and hands to observe participants’ reaction. The last camera was pointed to the monitor to record the experiment. The experiment’s videos show the four cameras’ views and some experiment information (e.g., speed, frame number, and time) for each frame. The videos were used for identifying the exact location of each zone, which is described in Figure 2, by determining the exact frame of each location. Consequently, driving behavior can be investigated accurately for each zone for each participant. …show more content…

The length of zone 1 is 0.25 miles located between point 1 (after the on-ramp) and point 2 (after the off-ramp). Zone 2 extends 0.25 miles between point 2 and point 3 (before the toll plaza). Zone 3 is the toll plaza zone with a length of 0.5 miles located between point 3 and point 4 (after the toll plaza). Finally, zone 4 is the area after the toll plaza and it extends 0.15 miles between point 4 and point 5 (before the final off-ramp).
