Pedestrian navigation services guide people to reach their destinations as the vehicle navigation services do. However, the moving way of people differs from that of vehicles, and hence the assumptions for car-navigation services are not suitable for pedestrian navigation. People may walk through the place without GPS signals due to the shelter in the sky. In some space, the accuracy of GPS may...

In this paper, a scheme is presented for fusing a foot-mounted Inertial Measurement Unit (IMU) and a floor map to provide ubiquitous positioning in a number of settings, such as in a supermarket as a shopping guide, in a fire emergency service for navigation, or with a hospital patient to be tracked. First, several Zero-Velocity Detection (ZDET) algorithms are compared and discussed when used i...

This work examines the relationship between 3-year pedestrian crash counts across Census tracts in Austin, Texas, and various land use, network, and demographic attributes, such as land use balance, residents' access to commercial land uses, sidewalk density, lane-mile densities (by roadway class), and population and employment densities (by type). The model specification allows for region-spec...

Urban planning has received tremendous public attention in the last few years. Energy cost, environmental issues, traffic congestion and the feeling of lack of belonging in the cities are among the factors that have contributed to the development of pedestrian areas. These public spaces provide opportunities for shopping, entertainment, eating facilities and gatherings where people can experien...

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 ...

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...
