Streets are large, diverse, and used for several (and possibly conflicting) transport modalities as well as social and cultural activities. Proper planning is essential and requires data. Manually fabricating data that represent streets (street reconstruction) is error-prone and time consuming. Automatising street reconstruction is a challenge because of the diversity, size, and scale of the de...

The objective of this study was to determine the annual incidence of fatal motor vehicle crashes involving street racing and to describe the characteristics of these crashes compared to other fatal crashes in the United States. The National Highway Traffic Safety Administration Fatality Analysis Reporting System data for 1998–2001 were used for the analyses. There were 149 568 fatal crashes and...

Street dust samples have been collected in different areas in Hong Kong associated with various levels of traffic and pedestrian flow, and the concentrations of 23 chemical elements have been determined using energy dispersive X-ray fluorescence (EDXRF). The 23 studied elements were Na, Al, Si, Cl, Ti, Ba, V, Cr, Mn, Fe, Co, K, Ca, Ni, Cu, Zn, As, Pb, Rb, Sr, Y, Zr and Sn. A profile for average...

A space-time network is used to model traffic flows over time for a capacitated road transportation system having one-way and two-way streets. Also, for the first time, traffic signal lights which change the network structure are explicitly incorporated into the model. A linear (time) cost per unit flow is associated with each arc, and it is shown that under the model structure, travel time on ...

As a subsystem of an Intelligent Transportation System (ITS), an Advanced Traveller Information System (ATIS) disseminates real-time traffic information to travellers. This paper analyses traffic flows data, describes methodology of traffic flows data processing and visualization in digital ArcGIS online maps. Calculation based on real time traffic data from equipped traffic sensors in Vilnius ...
