Available in PDF, EPUB and Kindle. Book excerpt: It is generally accepted that the level of service (LOS) at intersections significantly affects the overall LOS of the road system. It is also known that the LOS at an intersection can be adversely affected by frequently allowing left-turning vehicles to block through traffic. In addition, crash rates tend to be higher at intersections than on through sections of a road. The separation of left-turning vehicles from through traffic is therefore an important condition for the safe and effective operation of intersections. Existing guidelines for installing left-turn lanes have several limitations. They are mainly based on the traffic volumes at the intersection, and they use deterministic models with fixed gap acceptance and/or left-turn maneuver times. In addition, the guidelines for left-turn lanes for unsignalized intersections and signalized intersections must be specific for the type of intersection. In this study, new left-turn guidelines for both unsignalized and signalized intersections were developed on the basis of well-validated event-based simulation programs. Guidelines for unsignalized intersections were based on the percentage of left turns blocking through vehicles, whereas the guidelines for signalized intersections were developed using a minimum left-turn volume of either 85% left-turn capacity or LOS E delay (55 seconds/vehicle). In addition to the general guidelines, a prioritization tool that can be used to prioritize candidate intersections was developed. The prioritization tool accounts for both operational and safety aspects.

Book Synopsis Guidelines for Right-turn Treatments at Unsignalized Intersections and Driveways by : Tanweer Hasan
Download or read book Guidelines for Right-turn Treatments at Unsignalized Intersections and Driveways written by Tanweer Hasan and published by . This book was released on 1996 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: Guidelines for right-turn treatments at unsignalized intersections and driveways on the state highway system of Kansas were developed in this study. Two types of treatments, full-width lane and taper, were considered over the do-nothing radius treatment. THe guidelines were based on the results of an economic analysis conducted over a wide range of traffic volumes and speeds. A simple model was developed to determine the operational effects of right-turn movements at unsignalized intersections and driveways on high-speed highways. The operational effects were estimated in terms of delay and excess fuel consumption experienced by through vehicles due to the right turns. The relationship between speed differential and accidents was used to estimate the reduction in right-turn same direction rear-end accidents that would be expected to result from the provision of a right-turn treatment. Comparison with other guidelines and validation of existing right-turn treatments at the study sites indicate that the range of the guidelines developed in this study isre reasonable. They are also more definitive because they consider highway operating speed. They are more flexible in determining an appropriate treatment because an intermediate taper treatment is considered.

Book excerpt: In Missouri, multiple left-turns are gaining popularity. However, the installation of these multiple left-turn raises questions for which the Missouri Department of Transportation (MoDOT) has not yet developed answers. Specifically, MoDOT seeks guidance on: Criteria for determining when to install double and triple left-turns. The type of phasing to be used for dual and triple left-turn lanes. Whether to use "Dallas" or permitted lead-lag phasing for any left-turn lanes. Where to begin reducing the number receiving lanes downstream of an intersection with multiple left-turn lanes

Book Synopsis Guidelines for the inclusion of left-turn lanes at rural highway intersections by :
Download or read book Guidelines for the inclusion of left-turn lanes at rural highway intersections written by and published by . This book was released on 1970 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: Provision of left turn lanes is a major problem which lacks an objective approach. Various techniques and procedures in use have been reviewed. Traffic characteristics at typical Iowa intersections have been measured. A rational approach for inclusion of a left turn lane has been developed, based on relating the benefits to the road user to the cost of providing the added turing lane. An analysis of field data gathered under this project indicates that the use of theoretical distribution to describe vehicle headways is not applicable to rural Iowa two lane roads. As an alternate approach the mass of field data gathered were examined using multiple regression techniques to yield equations for predicting stops and delays. The benefit-cost ratio technique is recommended as the criterion for decision making.
Book Synopsis Development of Guidelines for Triple Left and Dual Right-turn Lanes by : Scott Allen Cooner

Available in PDF, EPUB and Kindle. Book excerpt: Left- or right-turn lanes at intersections improve safety and operations by separating turning and through vehicles. At intersections with heavy turning demand, it may be necessary to provide multiple turn lanes. Triple left-turn (TLT) and dual right-turn (DRT) lanes are still considered as relatively new designs that many agencies are reluctant to use, so they are somewhat limited in Texas. Guidelines for TLT or DRT lanes are almost nonexistent, leaving traffic engineers to rely on judgment for their designs. Therefore, their research was needed to develop consistence guidance. The 0-6112 project achieved two primary project goals: (1) development of geometric and signal design guidelines for TLT and DRT lanes; and (2) evaluation of the safety and operational performance of TLT and DRT sites in Texas. Researchers conducted field studies at 5 TLT and 20 DRT, primarily in the Dallas-Fort Worth and Houston urban areas, in order to evaluate lane utilization patterns, saturation flow rates, conflicts, and other operational factors. The research team also analyzed safety performance by investigating the crash history of the 25 sites using three techniques: collision diagrams, field conflict study, and comparison study. The results revealed that TLT lanes do not experience any major safety issues and also concluded that, in general, a well-designed DRT lane does not cause significantly higher crash frequency or severity compared to single right-turn lanes. Based on the results of this research and the geometric and signal design guidelines, Tudor and other agencies should be confident that well-designed TLT and DRT lanes can be implemented to address heavy turning demand at key intersections. The evaluation of these multiple turn lane sites in Texas revealed that they perform well from both operational and safety standpoints. TLT and DRT lanes are not appropriate for all situations, and their use should be supported by an operational analysis. Other techniques (grade separation, signal timing, etc.) might be better solutions for a particular site, especially when considering the effects of adjacent intersections, pedestrian/bicycle movements, and other key factors. Researchers developed a product, Keys to Successful Public Outreach, which is useful for implementing multiple turn lane projects.
