Available in PDF, EPUB and Kindle. Book excerpt: At rolling and slightly mountainous areas where the horizontal alignment is adequate for speeds of about 55 mph or more and where the grades do not cause trucks and truck combinations to travel markedly slower than cars, the best locations for the construction of passing lanes would often be the locations where the construction costs would be least regardless of whether or not there is an upgrade. However, there is no Caltrans data regarding the effectiveness of passing lanes at steep downgrades in terms of passing rates.

Download or read book Cost effectiveness of Passing Lanes written by Ata M. Khan and published by . This book was released on 1991 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: Program PCL is an interactive, screen-oriented, menu-driven, PC-based software package for the analysis of the effect of adding passing or climbing lanes to selected locations along two-lane rural highways. The main analysis functions choose the start and end locations of a climbing lane based on the speed differential of a heavily loaded truck; predicts the effects on level of service and average speed of adding a passing or climbing lane; and performs a cost effectiveness analysis based on reduction of delay and reduction in accidents. This programmer's manual provides a general overview of program logic and extensive documentation of the internal workings of some portions of the PCL program, including the utility module and application details.

This book was released on 1999 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Existing passing lanes in place on Kansas highways were studied from an operational and safety perspective. It was found that they generally operated well, improved operational efficiency and were well liked by the public. Determination of highway segments that would need passing lane(s) to improve their operational performance should be accomplished in a two-level process; i.e., Network and Project Level. At the Network Level, two-lane rural highway segments that operate at a level-of-service below a predefined acceptable level are identified. At the Project Level, highway segments identified at the network level are ranked for the purpose of prioritization. The number of highway segment passing lane projects to be implemented will depend on the funding level. At the project level, a detailed economic analysis of different passing lane lengths, spacing, and configurations can be undertaken to set parameters with an objective of minimizing percent time delay. Computer simulation using TWOPAS is a valuable tool to use at this level. The location of passing lanes should be planned along with their spacing. The location guidelines are based in part on the results of field studies, engineering judgement, and "common sense." The location guidelines can be grouped into four main considerations: safety, improved traffic performance, a design consistent with driver's expectation, and minimized construction costs. Spacing between any two successive passing lanes is intended to make the passing lanes function as a coordinated system. The effective length of a passing lane depends on traffic volume and composition, passing lane length, and downstream passing opportunities. The report also addresses the geometric elements relating to passing lanes, including lane and taper length and cross sections, and pavement marking and signing.
Download or read book Passing Lanes and Other Operational Improvements on Two lane Highways written by Douglas W. Harwood and published by . This book was released on 1986 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many two-lane highways in rural areas experience operational problems related to high traffic volumes; lack of adequate passing opportunities; slow-moving vehicles on grades and in rolling terrain; roadside development that generates turning maneuvers at driveways; and turning movements at intersections. This report evaluates five operational aids or treatments intended to alleviate these problems including: passing lanes, short four-lane sections, shoulder use sections, turnouts, and two-way left-turn lanes. The report reviews current signing, marking, and design practices used for these operational treatments in 13 states that participated in the study.

Available in PDF, EPUB and Kindle. Book excerpt: The objectives of this study are to demonstrate the feasibility and potential effectiveness of using passing lanes in Missouri, to evaluate the level of service and safety effects of existing passing lanes in Missouri, to establish criteria for determining where passing lanes could improve level of service and safety on Missouri highways, and to develop recommendations for the design, signing, and marking of passing lanes for potential application in Missouri. This report addresses the traffic operational and safety effectiveness of passing lanes as well as the geometric design and effective signing and marking of passing lanes. An evaluation of three existing passing lane sites on Missouri National Highway System (NHS) routes found that those passing lanes improve percent time spent following on those roads by 10 to 31% in comparison to a conventional two-lane highway without passing lanes. A safety evaluation found that the accident frequency per mi per year within passing lane sections on two-lane highways is 12 to 24% lower than for conventional two-lane highway sections. Criteria to determine where passing lanes could provide level of service and safety benefits on Missouri highways are presented. Case studies of locations on five Missouri NHS routes examined the potential traffic operational and safety effectiveness of alternative passing lane configurations.

Book excerpt: Many of the currently recommended saturation flow values used to determine the congestion level on a roadway are based on data collected in urban area traffic streams; therefore the resulting computational values reflect urban conditions. This project summarized existing research to offer alternative saturation flow rates that reflect rural conditions. It investigated a number of topics pertaining to rural area capacity and congestion. The issues considered were related to freeways, signalized intersections, two-lane road passing and climbing lanes, and access design. The project reviewed existing passing/climbing lane simulation packages, and examined certain volume, headway, and passing behaviors. The practice of assuming less than five second headways constitute delay was tested, and found to be questionable under certain circumstances. The performances of three different arterial street access designs in a small city were compared. The accident rates and travel time delays varied according to the level of access control present. The arterial with the most access control had a considerably lower accident rate than the other two arterials.
