Travels within the city are done in different ways, by vehicle or on foot. Thus, inevitably, a part of the travel is always done on foot. Since intersections as traffic nodes are determinant factor in transportation network capacity, any disruption in them leads to severe reduction in network capacity. Unfortunately, pedestrian behavior has received little attention in Iran. While this is a ver...

Conventional indicators using crowd density and pedestrian speeds can’t evaluate the walking condition of each pedestrian. This study aims to analyze acceleration elucidate relationship between them ease walking. For this research, mingling flow reproduction tests were carried out inside a motion-capture facility. Then, new graphic representation was created visualize acceleration. Furthermore,...

In metropolitan areas, a potentially large number of pedestrians depend either on transit or other modes for evacuation, or need to walk a distance to access their passenger cars. In the process of approaching some designated pick-up points for evacuation, the massive number of pedestrians may incur tremendous burden to the vehicles on the roadway network. Thus, an effective coordination betwee...

Predicting how changes to the urban environment will affect town centre vitality, mediated as pedestrian flows, is important for environmental, social and economic sustainability. This study is a longitudinal investigation of before and after urban environmental change in a town centre and its association with vitality. The case study baseline is Cardiff town centre in 2007, prior and after maj...

Video analysis of crowded scenes is challenging due to the complex motion of individual people in the scene. The collective motion of pedestrians form a crowd flow, but individuals often largely deviate from it as they anticipate and react to each other. Deviations from the crowd decreases the pedestrian’s efficiency: a sociological concept that measures the difference of actual motion from the...

One of the fundamental properties of pedestrian simulation models is their capability to predict the future movement dynamics of pedestrians depending on the current state of the pedestrian traffic flow, more specifically the walking behaviour of neighbouring pedestrians. This paper investigates the influence of the interaction characteristics on the strength of the reaction of pedestrians walk...

This paper presents a pedestrian detection method from a moving vehicle using optical flows and histogram of oriented gradients (HOG). A moving object is extracted from the relative motion by segmenting the region representing the same optical flows after compensating the egomotion of the camera. To obtain the optical flow, two consecutive images are divided into grid cells 14 × 14 pixels; then...

Walking, as an important transportation mode, plays a large part in urban transportation systems. This mode is of great importance for planners and decision-makers because of its impact on environmental and health aspects of communities. However, this mode is so complex in nature that makes it difficult to study or model. On the other hand, chaos theory studies complex dynamical nonlinear syste...

a pedestrian is every person who is walking, especially along or the width of a street or other place used by cars. growth, development and industrialization of societies, threatens the safety of pedestrians. increase and acceleration of vehicles and traffic, lack of road and street standards, weakness of laws or inappropriate executive guarantees, causing to insecurity and incidence of physica...
