Petrol is the most significant fuel and accounts for the largest consumption share among the various road transport energies. This paper presents different econometric modelling systems to estimate the demand for petrol in the Australian road transport sector, emphasizing the effects of national income and petrol price. Quarterly time series data for Australia over the period 1977-2006 are empl...

In this paper, we develop a novel link reliability model for vehicle ad hoc networks, which consist of vehicular wireless mobile terminals. In order to accurately present the vehicular mobility of the node, classic traffic theory is applied that discards the dependence on different vehicular mobility scenarios. Road density and terminal relative speed are introduced in our model. We demonstrate...

With growing interest in using cognitive radio (CR) technology in wireless communication systems for vehicles, it is envisioned that future vehicles will be CR-enabled. This paper discusses CR technologies for vehicular networks aimed at improving vehicular communication efficiency. CR for vehicular networks has the potential of becoming a killer CR application in the future due to a huge consu...

With the rapid growth and evolution of the vehicular network with the highly increasing demand of vehicular traffic management, vehicular infotainment applications, and the vehicular cloud computing, massive vehicular information is required to be downloaded from roadside-deployed gateways. With the nature of high mobility and intermittent connectivity, it is challenging to provide a highly rel...

With an increasing number of vehicles with significant computing and communication, many applications such as vehicular Internet hot-spots, digital and entertainment content’s broadcast, Intelligent Transportation Systems applications, and highway management will become possible. This “vehicular mobile commerce” will actively involve vehicles and users in both extending the existing mobile comm...

In Inter-Vehicular Adhoc Network (IVAN) does not have a fixed network topology but is highly dynamic. The topology of the network changes frequently because wireless links are established and broken down due to certain factors such as the velocity of the vehicles, their mobility patterns and their spatial density. These high dynamics also cause very short times for data transfer. This paper pre...

Vehicular emission (VE) is one of the important anthropogenic sources for airborne carbonyls in urban area. Six types of VE-dominated samples were collected at representative locations in Hong Kong where polluted by a particular fueled type of vehicles, including (i) a gas refilling taxis station (liquefied petroleum gas [LPG] emission); (ii) a light-duty passenger car park (gasoline emission);...

Understanding the sources of volatile organic compounds (VOCs) is essential for ground-level ozone and secondary organic aerosol (SOA) abatement measures. We made VOC measurements at 27 sites and online observations at an urban site in Beijing from July 2009 to January 2012. Based on these measurement data, we determined the spatial and temporal distribution of VOCs, estimated their annual emis...

Vehicular Networks are receiving a lot of attention due to the wide variety of services they can provide. Their applications range from safety and crash avoidance to Internet access and multimedia. A lot of work and research around the globe is being conducted to define the standards for vehicular communications. These include frequency allocation, standards for physical and link layers, routin...
