The vehicular flow in the urban street canyon is considered. The classical field description is used in the modelling of the vehicular movement and of gaseous mixture in generic urban street canyon. The dynamical variables include vehicular densities, velocities, and emissivities: of pollutants, heat and exhaust gases, as well as standard mixture components' variables: densities, velocities, te...

The major risks and sources of vulnerability, to which street children may be exposed, relate to shelter, safety and nutri­ tion. Specific health risks associated with untreated ill­ nesses and injuries, glue sniffing and sexual activities, are also threatening to them. In particular, street children are in danger from: • physical exposure to cold and damp, due to lack of shelter and insufficie...

Urban centres in the world are undergoing facets of changes, these changes are evident in developing countries and more divergent because urban transformation in developing countries is often accompanied challenges which include traffic congestion, overcrowding, pollution and continuous land use succession. This phenomenon is not different with the central area of Minna, Nigeria. Since 2008 the...

Many urban designers and researchers argue that walkable urban environments can encourage older residents' walking activities that benefit their physical health. However, walking also exposes older adults to safety risks, including due to traffic accidents. This study seeks to reveal the interactions between urban form and safety affecting urban baby boomers' walking behavior. Spatial analysis ...

Traffic supervision usually means the traffic work of police. Most people agree that traffic supervision is very important in preventing traffic accidents. Police activity, as it relates to highway safety, is a primary consideration in this paper. Perhaps traffic supervision may best be described as the elastic or flexible element in traffic safety programs— the work that fills in the gaps and ...

We examine the effect of citywide parking policy on and traffic demand. Using a large increase in on-street prices for city Amsterdam, we show that caused substantial drop demand, which is not offset by an off-street The overall reduction demand implies 2% – 3% traffic, confirmed with flow data. decline larger during evening peak, indicates are effective reducing congestion peak but less so mor...
