At present, there is still a lack of relevant theoretical guidance on the deployment roadside RSU expressways. In face coexistence V2V and V2I communication in future, adjustment after penetration intelligent vehicles not considered. Therefore, this paper proposes income model consideration influence communication. Based optimal nodes, it achieves optimization range determines spacing through f...

This paper presents a neural network based novel automated system that can analyze vehicle mounted video data for improving road safety. There are video data collection systems currently available although no tools exist which could be used to automatically analyze vehicle mounted video data and estimate future crash sites. The main aim of the research presented in this paper is to develop a te...

Nowadays urban pollution exposure from road transport has become a great concern in major cities throughout the world. A modelling framework has been developed to simulate Personal Exposure Frequency Distributions (PEFDs) as a function of urban background and roadside pollutant concentrations, under different traffic conditions. In this paper, we present a technique for classifying roads, accor...

According to car crash statistics, over sixmillionmotor vehicle crashes occur onU.S. highways each year. More than 42,000 people are killed in these accidents which injure three million others, and cost more than $230 billion each year. Astonishingly, five people die every hour in these crashes in the United States which is about one death every 12 minutes IVI (2001). In order to alleviate the ...

In recent years, wireless networks have become one of the most influential technological accomplishments and pervaded our daily lives in forms of mobile telephony and wireless computing. Due to their rapid development and widespread applications, trust, security, and privacy issues in wireless networks have become very important topics. As a result, there is a grand challenge to build wireless ...

Roadside point counts are generally used for large surveys to increase the number of samples. We examined differences in species detected from roadside versus off-road (200-m and 400-m) point counts in the Shenandoah National Park. We also compared the list of species detected in the first 3 minutes to those detected in 10 minutes for potential species biases. Results from 81 paired roadside an...

Finding a vacant parking space in a congested area, such as shopping mall, airport, etc., is always time-consuming and frustrating for drivers. Real-time parking information can avoid vehicles being cruising on the roads. However, when the drivers are acquiring parking information, their privacy is inevitable to be disclosed. In this paper, to minimize drivers’ hassle and preserve drivers’ priv...

Combustion-derived black carbon has received attention as a form of refractory organic carbon that may be preferentially preserved in soils and sediments. However, little is understood about the environmental roles of black carbon in urban soils. This investigation represented the preliminary study to characterize black carbon (BC) concentrations and enrichment ratios in Xuzhou urban roadside t...

Vehicular networks make use of the Roadside Units (RSUs) to enhance the communication capabilities of the vehicles in order to forward control messages and/or to provide Internet access to vehicles, drivers and passengers. Unfortunately, within vehicular networks, the wireless signal propagation is mostly affected by buildings and other obstacles (e.g., urban fixtures), in particular when consi...
