This paper applies method of continuous-time random walks for pedestrian flow simulation. In the model, pedestrians can walk forward or backward and turn left or right if there is no block. Velocities of pedestrian flow moving forward or diffusing are dominated by coefficients. The waiting time preceding each jump is assumed to follow an exponential distribution. To solve the model, a second-or...

CONTEXT Motor vehicles struck and killed 4739 pedestrians in the United States in the year 2000. Older pedestrians are at especially high risk. OBJECTIVE To determine whether crosswalk markings at urban intersections influence the risk of injury to older pedestrians. DESIGN Case-control study in which the units of study were crossing locations. SETTING Six cities in Washington and Califor...

In this paper, we develop a macroscopic model for pedestrian flow using the dynamic continuum modeling approach. We consider a two-dimensional walking facility that is represented as a continuum within which pedestrians can move freely in any direction. A pedestrian chooses a route based on his or her memory of the shortest path to the desired destination when the facility is empty and, at the ...

Pedestrian crowds can very realistically be simulated with a social force model which describes the different influences affecting individual pedestrian motion by a few simple force terms. The model is able to reproduce the emergence of several empirically observed collective patterns of motion. These self-organization phenomena can be utilized for new flow optimization methods which are indisp...

this research paper lays stress on philosophies of human desire. all the human being has some psychical need in addition to physical needs. and to satisfy the psychical needs, there is a need for stimulants, more in case of exclusive pedestrian precincts. having exclusively pedestrian precincts/cores in city design draws its inspiration from the fact that public zones, accessible to majority of...

Pedestrian detection is an important aspect of autonomous vehicle driving as recognizing pedestrians helps in reducing accidents between the vehicles and the pedestrians. In literature, feature based approaches have been mostly used for pedestrian detection. Features from different body portions are extracted and analyzed for interpreting the presence or absence of a person in a particular regi...

Title of dissertation: DEVELOPMENT OF A MIXED-FLOW OPTIMIZATION SYSTEM FOR EMERGENCY EVACUATION IN URBAN NETWORKS Xin Zhang, Doctor of Philosophy, 2012 Dissertation directed by: Professor Gang-len Chang Department of Civil & Environmental Engineering In most metropolitan areas, an emergency evacuation may demand a potentially large number of evacuees to use transit systems or to walk over some ...
