The increasing number of smart vehicles and their resource hungry applications pose new challenges in terms of computation and processing for providing reliable and efficient vehicular services. Mobile Edge Computing (MEC) is a new paradigm with potential to improve vehicular services through computation offloading in close proximity to mobile vehicles. However, in the road with dense traffic flow,...
Cloud-based vehicular networks is a new paradigm to improve the vehicular services through distributing computation tasks between remote clouds and local vehicular terminals. To further reduce the latency and the transmission cost of the computation offloading, we propose a cloud-based Mobile Edge Computing (MEC) offloading framework in vehicular networks. In the framework, efficient computation offloading...
Vehicular heterogeneous networks (VHNs) are a special type of wireless vehicular networks. In the VHNs, the nodes choose an access network to download data from the Internet. Most of the existing access network selection mechanisms concentrate on the perspective of individual nodes, only limited work focus on cooperative communications among vehicles. In this paper, a new network selection approach...
A scientific and effective evacuation plan plays an important role in improving the event reaction ability of the urban traffic system. Many unpredictable natural or man-made disasters result in no-notice evacuation events. This type evacuation has a main trait different with tradition hurricane evacuation and no time to evacuate by their cars. Such specific characteristics of the no-notice evacuation...
In this paper, toll collection data in Guang Dong province are investigated. After pre-processing data, we obtain spatial characteristics and temporal characteristics of OD-Matrix, and further we take insight into the travel times among different vehicle types. The results obtained in this paper extend the corresponding results given in previous works. The study is very important to traffic management...
The freeway network has been constructed in most of the provinces. However, different with city highways, due to the lack of data collecting device in long distance, information services on freeways are very limited. This paper introduced a Traffic Information System based on the Toll Collection Data (TIS-TCD) on expressway. Based on the toll collection data of Guangdong province, several information...
More and more real-time traveler information Websites have been set up to provide real-time traffic condition information. They derive traffic conditions with different algorithms based on different data sources. We have found that there is a discrepancy among those Websites. This certainly confuses users because they provide inconsistent traffic condition information. As known, people draw conclusions...
