Pedestrian crowd simulation explores crowd behaviors in virtual environments. It is extensively studied in many areas, such as safety and civil engineering, transportation, social science, entertainment industry and so on. As a common phenomenon in pedestrian crowds, grouping can play important roles in crowd behaviors. To achieve more realistic simulations, it is important to support group mod...

BACKGROUND Each year about one million people die and about 10 million are seriously injured on the world's roads. Educational measures to teach pedestrians how to cope with the traffic environment are considered to be an essential component of any prevention strategy, and pedestrian education has been recommended in many countries. However, as resources available for road safety are limited, a...

Observation in absolute darkness and daytime under every atmospheric situation is one of the advantages of thermal imaging systems. In spite of increasing trend of using these systems, there are still lots of difficulties in analysing thermal images due to the variable features of pedestrians and atmospheric situations. In this paper an efficient method is proposed for detecting pedestrians in ...

conclusions geographic accessibility of pharmacies at night and on holidays has to be addressed by provincial health policymakers. materials and methods the analysis was based on straight-line distance measurements. we considered 150, 300, 450, 600, and 750 m for pedestrians, and 1, 2, and 3 km for driving accessibility as the acceptable distances. we calculated the number and percentage of hou...

This paper investigates the causal effect of pedestrian environments on walking behavior and focuses on the issue of research design. The paper differentiates between two types of research designs: treatment-based and traveler-based. The first approach emphasizes the variation of the treatment (pedestrian environments), and generally compares distinct neighborhoods, such as urban vs. suburban o...

We extend the Aw-Rascle macroscopic model of car traffic into a two-way multilane model of pedestrian traffic. Within this model, we propose a technique for the handling of the congestion constraint, i.e. the fact that the pedestrian density cannot exceed a maximal density corresponding to contact between pedestrians. In a first step, we propose a singularly perturbed pressure relation which mo...

An autistic child was taught pedestrian skills in a classroom by use of a model of the streets and the intersection she most often frequented. She manipulated a doll and verbalized what the doll was doing to get to the designated location. After mastering the pedestrian skills on the model, video recordings familiarized her with traffic at local intersections. She successfully generalized the p...

In the present paper scalar macroscopic models for traffic and pedestrian flows are coupled and the resulting system is investigated numerically. For the traffic flow the classical Lighthill-Whitham model on a network of roads and for the pedestrian flow the Hughes model are used. These models are coupled via terms in the fundamental diagrams modeling an influence of the traffic and pedestrian ...

this article is an attempt to study the development compatibility between pedestrian spaces of bazaar and tarbiat pedestrian malls in tabriz. the importance of this issue is due to the subject that today following the discussions on human development and environmental conditions, pedestrian spaces have been taken into consideration by planners and designers as one of the important strategies of...
