“…The main control objective is the work zone throughput. Yulong and Leilei [33] proposed the control flow of Intelligent Lane Merge Control System with Intelligent Transportation System (ITS) techniques. The ITS is also considered by Jacob et al [34], utilized reinforcement learning-based optimal control.…”

Road construction and maintenance activities cause traffic congestions and delays and present challenges for ensuring the safety of both motorists and road workers. While urban areas are well-equipped with traffic devices, in the case of highways our chances to collect traffic data and control traffic flows may be limited. Then the use of a temporary Highway Traffic Management System seems to be a suitable solution. Although the impacts of its deployment are addressed by many theoretical studies and demonstrated on traffic simulation models, there are not many references dealing with field tests. We provide results of the practical evaluation of the temporary Highway Management System installed and tested on the main highway in the Czech Republic during the road works period. Before-after analysis of collected traffic data was performed to prove the importance and positive impact of the proposed solution. We demonstrate an over 20% increase in the capacity of the roadwork zone and an almost 30 seconds decrease in average delay for one vehicle Highway administrators can use the results to justify investments into the temporary deployment of mobile traffic management systems.

“…Kang, Chang, and Panacha found that dynamic late merge could lead to up to an 11% increase in work zone throughput compared with no-merge control (25). Yulong and Leilei developed an intelligent lane merge control system similar to dynamic late merge (26). According to the results of their study, dynamic late merge control and intelligent lane merge increased the work zone capacity by 8% and 20%, respectively, compared with static late-merge control.…”

This paper presents the development of a four-regime speed–flow relationship for highway work zones and the effects of police presence (police) and speed photo enforcement (SPE) on the speed–flow relationship and capacity. The base data were collected when signage typical of that shown in the Manual on Uniform Traffic Control Devices for an Interstate highway work zone with no lane reduction was present. Police and SPE data were collected, respectively, when a police patrol car and an SPE van were added to the typical work zone. From each data set, the step-by-step progression from a three-regime model based on least-squares regression to a four-regime speed–flow curve is presented. The four-regime model comprises four equations: (a) horizontal line for free-flow regime that covered the volume levels up to 900 passenger cars per hour per lane, (b) fourth-degree spline for the upper transition part of the speed–flow curve, (c) another fourth-degree spline for the lower transitions part, and (d) equation in the form of power function for the highly congested part of the speed–flow relationship. The speed–flow curve for the base case had a free-flow speed (FFS) of 61.3 mph and a capacity of 1,850 per car per hour per lane (pcphpl). In the police case, however, the FFS and capacity were reduced by 6.3 mph and 50 pcphpl, respectively. For the SPE case, the FFS and capacity were also reduced by 6.8 mph and 100 pcphpl, respectively. The new curves provided the more accurate speed and work zone capacity estimations required for efficient operation.

“…However, these approaches fail in the presence of unexpected events such as accidents and road works, which cause sudden bottlenecks and may lead to prolonged congestion [9]. To address the uncertainties arising from the occurrence of such events, we propose an active approach to providing guaranteed arrival times.…”

Abstract-To address the goal of providing drivers on highways with guaranteed arrival times, we propose a traffic management system that combines virtual slots with semiautonomous driving to shape traffic and prevent congestion. Two algorithms that address aligning vehicles into slots and efficient merging from three to two lanes are proposed. Furthermore, an implementation and evaluation of these algorithms using the VISSIM traffic simulator is presented. Our initial results indicate that a slot-based system has the potential to be used to guarantee arrival times and provide a significant overall increase in efficiency when compared against a human driving model.
