An Assessment of the Impact of Pedestrian Refuge Islands on Vehicle Speed Changes and Pedestrian Safety: Case Study in Tehran
Pedestrians are among the most vulnerable road users. Speed of vehicles is considered as one of the major causes of danger for pedestrians crossing the street. Therefore, it is of utmost importance to devise suitable solutions to reduce speed of vehicles. One of these solutions is installation of Pedestrian Refuge Islands (PRI) in very wide midblocks. With regard to fluctuations in pedestrian a...
متن کاملPedestrian head translation, rotation and impact velocity: the influence of vehicle speed, pedestrian speed and pedestrian gait.
In road traffic collisions, pedestrian injuries and fatalities account for approximately 11% and 20% of casualties in the USA and the EU, respectively. In many less motorised countries, the majority of victims are pedestrians. The significant influences of vehicle speed, pedestrian speed and pedestrian gait on pedestrian post-impact kinematics have been qualitatively noted in the literature, bu...
متن کاملObstacle Detection and Avoidance on Sidewalks
We present part of a vision system for blind and visually impaired people. It detects obstacles on sidewalks and provides guidance to avoid them. Obstacles are trees, light poles, trash cans, holes, branches, stones and other objects at a distance of 3 to 5 meters from the camera position. The system first detects the sidewalk borders, using edge information in combination with a tracking mask,...
متن کاملFree Speed Distributions for Pedestrian Traffic
Free speeds are defined as the speeds pedestrians like to walk with when they are not influenced by other nearby pedestrians. Free speeds differ among pedestrians being influenced by personal characteristics, characteristics of the infrastructure and external conditions. Free speeds and their distribution play an important role in many traffic flow models, but are also relevant in other applica...
متن کاملCollision-free speed model for pedestrian dynamics
We propose in this paper a minimal speed-based pedestrian model for which particle dynamics are intrinsically collision-free. The speed model is an optimal velocity function depending on the agent length (i.e. particle diameter), maximum speed and time gap parameters. The direction model is a weighted sum of exponential repulsion from the neighbors, calibrated by the repulsion rate and distance...
