Traffic intelligence has become an important part of the development various countries and automobile industry. Roadside perception is intelligent transportation system, which mainly realizes effective road environment information by using sensors installed on roadside. Vehicles are main targets in most traffic scenes, so tracking a large number vehicles subject field roadside perception. Consi...

We propose a protocol suite for communication amongst mobile and roadside Intelligent Vehicle Highway Systems (IVHS). The suite seeks inspiration from ISO/OSI addressing and systems management paradigms, as well as from the Internet UDP, and is partly implemented and thus validated on a Telia Research short-range communication testbed.

During the last decade, the research on vehicular networks has led to the proposal of countless network solutions specifically designed for vehicular environments. Such solutions encompass all network paradigms,with original algorithms and architectures proposed for next-generation roadside cellular access networks, pure vehicular ad hoc networks, and opportunistic disruption-tolerant vehicular...

The distributions of nanoparticles (below 300 nm in diameter) change rapidly after 7 emission from the tail pipe of a moving vehicle due to the influence of transformation processes. 8 Information on this time scale is important for modelling of nanoparticle dispersion but is 9 unknown because the sampling frequencies of available instruments are unable to capture these 10 rapid processes. In t...

stimates of the health effects of air pollution are alarming , with up to 7 million attributable deaths worldwide each year. Although the pulmonary effects of air pollution are widely recognized, it is only in the last few decades that the adverse cardiovascular effects of air pollution have become apparent. Exposures to diesel exhaust, a prominent source of urban air pollution and a pollutant ...

This research examines traffic-source trace elements accumulations and distributions in roadside soils and wild grasses in the Qinghai-Tibet Plateau. A total of 100 soil samples and 100 grass samples including Achnatherum splendens, Anaphalis nepalensis, Artemisia sphaerocephala, Carex moorcroftii, Iris lacteal, Kobresia myosuroides, Oreosolen wattii, Oxytropis ochrocephala and Stellera chamaej...
