Abstract:
Although there are many international standards of walkway design, walking behaviors are different in each country/region. To determine the pedestrian characteristics the concept of the social force model, which is analogous to resolving forces in Newtonian mechanics was adopted. Behavioral data related to pedestrian walking speed were collected by using a digital camera at BTS (Bangkok Transit System) station and manually extracted needed factors like pedestrian speed, density and others. After completing the calibration and validation process using a VISSIM microsimulation technique, pedestrian walking speed is analyzed on the basis of density. The analysis shows that the walking speed of pedestrians is 75.07 m/min, which is slower than the U.S. pedestrians. It is also found that the walking speed and the body size directly affect the pedestrian flow rate. A similar traffic microsimulation model has also been applied to analyze the pedestrian capacity that is calibrated by adjustin
g pedestrian speed. Due to the smaller body size of Asians compared to Americans, the flow rate observed in this study is higher. In particular, the pedestrian capacities per one-meter width of uni-direction and bi-direction are 91 peds/m/min and 78 peds/m/min, respectively.
