Previously, we conducted a roadside survey to reveal the occurrence of genetically modified (GM) oilseed rape along a Japanese roadside (Route 51). In this study, we performed successive and thorough fixed-route monitoring in 5 sections along another road (Route 23). Oilseed rape plants were detected on both sides of the road in each section between autumn 2009 and winter 2013, which included 3...

Introduction The impending widespread deployment of Vehicular Ad Hoc Networks (VANETs) has created an opportunity for multimedia communication not only as part of vehicle safety provision, traffic management, and emergency response but also in the value-added ‘infotainment’ domain. The key feature of video distribution to the passengers of vehicles or crew members of emergency vehicles in the V...

Vehicular emission is an important source of air pollutants in urban cities in the Pearl River Delta (PRD) region of South China. In order to study the impact of evaporative loss of vehicular fuel on air quality, several commonly used fuel samples were collected in four main cities in the PRD region – Hong Kong, Guangzhou, Macau and Zhuhai, and analyzed for their volatile organic compounds (VOC...

Operational speed is an index that represents drivers’ speeding behaviors and shows the comfort and safety levels they experience. Many models had been proposed to predict operational speed in tangent and curve segments of highways. Most of these works had used geometric, with few of them conducted using roadside variables to predict operational speed. Also, the operational speed study in multi...

Highway and roadside safety features are crash tested for compliance with certain safety criteria. US Federal Highway Administration (FHWA) uses a surrogate reusable test vehicle, Bogie, to conduct crash tests of roadside safety features. Bogie is intended to replace an impacting vehicle in order to reduce the cost of the test. Bogie can be configured with different crushable impact noses repre...

This work describes the results of assessment of the heavy metals, Cd, Co, Cr, Cu, Mn, Ni, Pb, and Zn in urban soil of Guwahati City, India from 31 sites of five different land use types covering residential, commercial, industrial, public utilities, and roadside. Sequential extraction procedure was used to evaluate the relative distribution of the eight metals in exchangeable, carbonate, reduc...

The rapid expansion of urbanization has caused land cover change, especially the increasing area of impervious surfaces. Such alterations have significant effects on the soil ecosystem by impeding the exchange of gasses, water, and materials between soil and the atmosphere. It is unclear whether impervious surfaces have any effects on soil bacterial diversity and community composition. In the p...

Dedicated Short Range Communications (DSRC) is an emerging technology that connects automobiles with each other and with roadside infrastructure. The U.S. Department of Transportation may soon mandate that cars be equipped with DSRC to enhance safety. This work finds that if they do, then DSRC networks could also be an important new way to provide Internet access in urban areas that is more cos...

India is a nation which has the one of the largest NonLane based road network in the world. Many developed nations today use Intelligent Transportation system (ITS) to solve traffic related problems and provide smooth and safe ride on roads. The road traffic congestions are recurring problem in India. One of the major reasons that lead to traffic congestion is the poor infrastructure and attitu...

Roadside LiDAR has become an important sensor for the detection of objects in cities, such as vehicles and pedestrians, which is due to its advantages all-weather operation high-ranging accuracy. In order serve intelligent transportation system, efficient accurate segmentation pedestrians needed coverage area LiDAR. this study, a roadside was fixed on brackets both sides road obtain point-cloud...
