As urban transportation planning becomes more sophisticated, the accurate detection and counting of pedestrians and bicyclists becomes more important. In this project, two distinct camera-based approaches are integrated together to create a real-time pedestrian and bicyclist counting system which is regularly accurate to 85% and often achieves higher accuracy. The primary approach retasks a sta...

For the purposes of both traffic-light control and the design of roadway layouts, it is important to understand pedestrian street-crossing behavior because it is not only crucial for improving pedestrian safety but also helps to optimize vehicle flow. This paper explores the mechanism of pedestrian street crossings during the red-man phase of traffic light signals and proposes a model for pedes...

Synthetic mobility models can be used to simulate the movement of a traffic unit or a group of traffic units in a telecommunication network. Characteristics of pedestrian and vehicular traffic, such as speed-flow, speed-density and flow density are often neglected in current synthetic mobility models. The analysis, emulation and simulation of telecommunication networks with mobile users using m...

Pedestrian simulation is complex because there are different levels of behavior modeling. At the lowest level, local interactions between agents occur; at the middle level, strategic and tactical behaviors appear like overtakings or route choices; and at the highest level path-planning is necessary. The agent-based pedestrian simulators either focus on a specific level (mainly in the lower one)...

Mobile communication devices may be used for spreading multimedia data without support of an infrastructure. Such a scheme, where the data is carried by people walking around and relayed from device to device by means of short range radio, could potentially form a public content distribution system that spans vast urban areas. The transport mechanism is the flow of people and it can be studied ...

An organized evacuation of pedestrians entrapped in a building in emergencies such as those caused by fire, bomb blast, or intentional or unintentional release of toxins in the environment is of utmost importance. The focus of this study is on the development of a formal control methodology for an orderly and jam-free evacuation of pedestrians entrapped in a network of corridors in buildings in...

Pedestrians are the most vulnerable road users. For evaluating and modifying pedestrian safety in unsignalized crosswalks,the first important issue is to identify and explore factors affecting the interaction behavior of pedestrians andvehicles in conflict areas. By analyzing those factors and determining how they affect road user's behavior, we canrepresent the plans and proc...

Numerous evacuation models are developed since decade ago in order to offer an appropriate design to estimate the required time for evacuating from a variety of places with various conditions. Thus, high traffic buildings found in governmental or industrial are essential to accurately evaluate the require time for evacuation process in order to ensure the safety of pedestrians. Thus, in order t...

Mobile communication devices may be used for spreading multimedia data without support of an infrastructure. Such a scheme, where the data is carried by people walking around and relayed from device to device by means of short range radio, could potentially form a public content distribution system that spans vast urban areas. There are basically only three system parameters that can be determi...
