| Abstract | \'\'Pedestrian-Vehicle Interaction at a Marked Mid-block Crosswalk in Bangkok" is an experimental study which has been organized into four parts.
The first part consisted of analyzing and evaluating vehicular motion in the vicinity of the crosswalk. It was found that far side vehicles and fast vehicles are more dangerous than near side vehicles and slow vehicles. The delay to vehicles due to individual pedestrians
is not appreciable, with a portion of the drivers preferring to risk
hitting the pedestrian rather than slowing down. The second part of the study was to measure and analyze pedestrian
movements during crossing. It was found that the starting time in accepting gaps and lags are statistically different. The walking rate beyond a 8.5-sec pedestrian-vehicle time interval is steady and equal to 4.5 ft/sec. More than 85 percent of the drivers did not slow down for cases in which the reserve time of the pedestrians was greater
than 3 seconds. The third part of the study was to measure and identify the gap and lag acceptance distribution for different sequences of vehicles.
It was found that a larger near-far gap is needed than a near-near gap, but that the far-near gap and far-far gap can be of a shorter duration than a near-near gap. A far side lag needs to be longer than a near side lag.
The last part of the study was to determine the waiting time of
pedestrians in terms of the traffic volume. It is shown that the experimental measurements fit very closely to some theoretical formulas. |
