Retracted

This paper has been retracted as it was accepted for publication on the basis of peer review reports that were submitted from fraudulent reviewer accounts.

In late 2014, a number of publishers discovered widespread abuse of the peer review process, including cases of identity theft and faked review reports. In July 2015, Hindawi concluded an extensive investigation into peer review fraud and identified a number of articles that had been accepted on the basis of fraudulent peer review reports.

In accordance with the guidelines of the Committee on Publication Ethics (COPE), this article has been retracted on the basis that fraudulent review reports were submitted by one of the article’s co-authors, Jason Jung.

Abstract

Variable speed limits (VSLs) as a mean for enhancing road traffic safety are studied for decades to modify the speed limit based on the prevailing road circumstances. In this study the pros and cons of VSL systems and their effects on traffic controlling efficiency are summarized. Despite the potential effectiveness of utilizing VSLs, we have witnessed that the effectiveness of this system is impacted by factors such as VSL control strategy used and the level of driver compliance. Hence, the proposed approach called Intelligent Advisory Speed Limit Dedication (IASLD) as the novel VSL control strategy which considers the driver compliance aims to improve the traffic flow and occupancy of vehicles in addition to amelioration of vehicle’s travel times. The IASLD provides the advisory speed limit for each vehicle exclusively based on the vehicle’s characteristics including the vehicle type, size, and safety capabilities as well as traffic and weather conditions. The proposed approach takes advantage of vehicular ad hoc network (VANET) to accelerate its performance, in the way that simulation results demonstrate the reduction of incident detection time up to 31.2% in comparison with traditional VSL strategy. The simulation results similarly indicate the improvement of traffic flow efficiency, occupancy, and travel time in different conditions.
