Abstract
- Saturation flow rate is a key design parameter in the analysis of Level of Service and capacity of signalized intersections. In developing countries like India, pedestrians are observed to cross and interfere with the vehicular flow irrespective of signal provisions for their crossing. This results in unanticipated pedestrian-vehicle interactions at signalized intersections and effects the saturation flow estimation. In the present research work, pedestrian crossing effect on saturation flow is studied. Six signalized intersections are chosen from three cities to study the illegal pedestrian crossing on saturation flow. Width of approach, green time, percentage of two-wheeler and number of illegal pedestrian crossings are found to affect the saturation flow. A multiple linear regression model is developed for the estimation of saturation flow. In addition to the development of saturation flow model, this paper presents adjustment factors for pedestrians to incorporate the effect of unauthorized pedestrian crossing. [ABSTRACT FROM AUTHOR]
