This book was released on 2014 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the United States, intersections are among the most frequent locations for crashes. One of the major problems at signalized intersection is the dilemma zone, which is caused by false driver behavior during the yellow interval. This research evaluated driver behavior during the yellow interval at signalized intersections and compared different dilemma zone countermeasures. The study was conducted through four stages. First, the driver behavior during the yellow interval were collected and analyzed. Eight variables, which are related to risky situations, are considered. The impact factors of drivers' stop/go decisions and the presence of the red-light running (RLR) violations were also analyzed. Second, based on the field data, a logistic model, which is a function of speed, distance to the stop line and the lead/follow position of the vehicle, was developed to predict drivers' stop/go decisions. Meanwhile, Cellular Automata (CA) models for the movement at the signalized intersection were developed. In this study, four different simulation scenarios were established, including the typical intersection signal, signal with flashing green phases, the intersection with pavement marking upstream of the approach, and the intersection with a new countermeasure: adding an auxiliary flashing indication next to the pavement marking. When vehicles are approaching the intersection with a speed lower than the speed limit of the intersection approach, the auxiliary flashing yellow indication will begin flashing before the yellow phase. If the vehicle that has not passed the pavement marking before the onset of the auxiliary flashing yellow indication and can see the flashing indication, the driver should choose to stop during the yellow interval.

Available in PDF, EPUB and Kindle. Book excerpt: "Driver behavior within the dilemma zone can be a major safety concern at high-speed signalized intersections, especially for heavy trucks. The Nebraska Department of ROADS (NDOR) has developed an implemented an Actuated Advance Warning (AAW) dilemma zone protection system. The AAW system has been documented as being effective at improving traffic safety at isolated signalized intersections. However, the system is yet to be used at signalized intersections operating in the coordinated mode. This study tested the feasibility of deploying the system on arterials where the signals are closely spaced and operate in a coordinated mode. A microsimulation approach -- integration of traffic microsimulation and surrogate safety performance measures -- was developed to assess the potential benefits (safety and operation) in-lieu of observed traffic and crash data. The analysis of conflicts indicated that, on average, there were 30%, 7%, and 30% reductions in the number of rear-end, lane change, and crossing conflicts respectively when the AAW system was used. In terms of the relative productivity of the system, the number of vehicles that were processed during a specified analysis period revealed that there were generally more vehicles processed when the AAW system was not in place. Also, the overall link travel times were slightly higher when the system was in place" (page viii).

This book was released on 2001 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: A feasibility study of dilemma zone problems, performed by collecting and analyzing traffic flow data at a high-speed signalized intersection, showed that the maximum green extension or cutback needed to get a vehicle out of the dilemma zone is generally no more than 2 seconds. If we scan all vehicles on a link just a few seconds before the beginning of a yellow interval, we may be able to extend or cut back the green interval so that the vehicles can avoid the dilemma zone. For each vehicle approaching an intersection on the link that is about to turn yellow, there is a time interval such that (a) the vehicle will be in the dilemma zone without green extension (or cutback) or (b) it will be in the dilemma zone when there are T seconds of extension (or cutback). So the task is to find the smallest nonnegative integer T that is not in any of these time intervals and extend (or cut back) the current interval by T seconds. This T can always be found and assuming there are no other restrictions, dilemma zones can be avoided and the extension (or cutback) is done at most once for each green interval. The simulation study, performed by modifying the source codes of NETSIM, showed that the signal timing generated by a bandwidth maximization program (PASSER-II) resulted in a lower number of vehicles in the dilemma zone than that generated by a delay minimization program (TRANSYT-7F). Additionally, the signal timing generated by the combination of the two programs, that is, by minimizing delay within the constraint of bandwidth maximization, resulted in an even lower number of vehicles in the dilemma zone than those generated by each program alone. The technique developed in this study can be implemented if the speeds and positions of all vehicles on the roadway can be recorded at small time intervals (e.g., 1 sec). Recommendations are made for implementing and testing the developed technique.

This book was released on 2005 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Historically, high speed signalized intersections have reported many crashes and have always posed a challenge to traffic engineers for enhancing safety at these intersections. The area close to the intersection, called the dilemma zone, poses a high accident potential for the driver in stopping safely during the yellow interval or in proceeding through the intersection before the beginning of red. The driver is in a potentially hazardous situation whereby, if he tries to cross the intersection at the onset of red interval, he may end up in an angle accident with the cross street traffic or if he accelerates through yellow, he may end up in a rear-end collision. The uncertain situation in a dilemma zone can potentially lead to rear-end or right angle collisions.

Download or read book Fuzzy Logic for Improved Dilemma Zone Identification written by Derek Adam Moore and published by . This book was released on 2012 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Type-II dilemma zone refers to the segment of roadway approaching an intersection where drivers have difficulty deciding to stop or proceed through at the onset of the circular yellow (CY) indication. Signalized intersection safety can be improved when the dilemma zone is correctly identified and steps are taken to reduce the likelihood that vehicles are caught in it. This research employs driving simulation as a means to collect driver response data at the onset of the CY indication to better understand and describe the dilemma zone. The data obtained was compared against that from previous experiments documented in the literature and the evidence suggests that driving simulator data is valid for describing driver behavior under the given conditions. Fuzzy logic was proposed as a tool to model driver behavior in the dilemma zone, and three such models were developed to describe driver behavior as it relates to the speed and position of the vehicle. These models were shown to be consistent with previous research on this subject and were able to predict driver behavior with up to 90% accuracy.

This book was released on 2010 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Safety and efficiency are both major concern at high-speed intersections. It has been a major challenge for traffic engineers over the years to increase efficiency without sacrificing delay. An IntelliDrive signal control system was developed in the University of Akron's transportation lab based on the concept of IntelliDrive technology that can improve safety significantly while retaining efficiency. The new intelligent signal control system can address the dynamic dilemma zone problem, thus providing maximum safety at intersections. Every vehicle in the system is addressed to its own dilemma boundary rather than addressing dilemma zone for the whole intersection approach. By obtaining advance speed information, vehicle classification, vehicle location from the stop line, for every vehicle for every second in the system in real time, unneeded extensions can be avoided. Thus the intersection not only operates more safely, but also more efficiently because of the proposed algorithm logic that utilizes IntelliDrive technology. IntelliDrive test bed was created in VISSIM simulation platform and tested for operational efficiency when safety criteria are met. This thesis also discusses the characteristics of the Peak Flow Factor (PFF) which is the ratio between peak hourly volume and peak flow rate within the hour. Despite the fact that the Highway Capacity Manual (HCM) requires use of this ratio in evaluating the Levels of Service (LOS) of roadway facilities, a very limited amount of prior research has been made on its variability. Subsequently, the HCM established a time interval of 15 minutes for obtaining the peak flow rate without much explanation on why this time interval was chosen. In order to investigate the PFF's effectiveness for representing the variation of flow within peak hour, this research focuses on PFF analysis and time series models of the PFF at various time intervals for signalized isolated intersections. Results showed that the PFF decreased when time interval decreased and that significant differences in the stability were apparent when each time interval were compared. In addition, the developed time series models showed the the[sic] PFF can be forecasted with relative accuracy and simulation models within this study demonstrated the test results from data are dependable."--Abstract.
