The concept of complex event processing (CEP) and complex-event-aware service have been extensively studied to retrieve relevant information from massive amount of realtime streaming events. In mobile environment, the Mobilityaware CEP (MCEP) system was proposed to address the issue of synchronization problem between different query ranges and MCEP operators. We noticed that MCEP systems lack the...
It is well known that limited safety distance and excessive intersections are the main reasons of the increasing traffic accidents on arterial roads. Based on the highway functional classification and intersection control types, the intersection spacing mode is divided firstly to make sure the arterial road access spacing and intersection corner clearance as the research object. Then for the concept...
Death and injuries as a result of road accidents is a recognized global problem and authorities are aware of the consequences this global phenomenon might lead to. Roadway safety is one of the most important issues in transportation. Intersections are the locations with higher traffic crashes as compared with other roadway locations. This paper introduces an approach to evaluate roadway intersection...
Traffic accidents usually induce non-recurrent congestions in the urban transportation network. In order to avoid the congestion deterioration, the paper presented a method to make traffic dispersion plans. The method considered and harmonized multi-objective, such as the change in total travel time, restrictions of traffic volumes on the links, and changes in traffic volumes on the links. Firstly,...
The unique characteristics of highway intersections have caused them to be the most dangerous places in the road system. Complexity of causes of traffic crashes at highway intersections, difficulty in data collection of traffic accidents and traffic conflicts and many other reasons have made safety performance evaluation of highway intersections one of the most difficult tasks, in spite of the fact...
