This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Rural two-lane highways make up a large portion of road networks around the world. The special geometric and traffic attributes of these highways pose special challenges to safety and traffic operation. In recent years, microscopic simulation models have gained increased acceptance as a reliable tool for investigating traffic operations and evaluating safety performance. Despite this trend, the development and application of these models to two-lane highway operations has not kept pace with those of freeways and urban networks, and this is due, in large part, to difficulties in modeling the overtaking process. This process has been rendered complex by the large number of inter-related decision factors that need to be considered by the overtaking driver in a bi-directional driving regime. In this research, a new overtaking gap-acceptance model is developed to simulate traffic operation and safety performance on two-lane highways. This model considers a wide spectrum of physical and behavioral variables that could affect overtaking. It does so by introducing a new safety-based gap-acceptance decision variable based on the overtaking driver's perception of time-to-collision (TTC) with an opposing vehicle. The decision to overtake was expressed as a function of the perceived TTC in comparison to an established driver risk threshold (critical TTC). The distribution of critical TTC among drivers are determined through a model calibration and validation procedure based on overtaking observational data obtained from a video-recording of a one-kilometer segment of a two-lane highway. Unlike previous models, the proposed gap-acceptance model makes use of only a few calibration parameters. The proposed overtaking models along with other components of a micro-simulation traffic model are implemented in a software framework that can simulate traffic and safety operation for two-lane highways. The overall simulation results demonstrate that the proposed simulation model can provide reliable measures of traffic and safety for two-lane highway operation. The overtaking model was found to yield both consistent and transferable results. The model is then applied successfully to provide more accurate estimates of traffic measures used in level-of-service analysis for two-lane highways and to compare these results to values reported in the two versions of the Highway Capacity Manual (HCM). In another application, this model is used to investigate the impact of truck mandated speed limiters on safety and traffic operation of two-lane highways and specifically their impact on overtaking. Finally, the potential implications of adaptive cruise control for overtaking and its resultant traffic and safety impacts are studied using the developed simulation model.

Available in PDF, EPUB and Kindle. Book excerpt: This project presents research on estimating traffic performance on two-lane, twoway highways. The main research objective is to examine two new approaches / methodologies in estimating the Percent-Time-Spent-Following (PTSF), a major indicator of performance on two-lane highways. The first new approach, named the weighted-average approach, is based on the weighted average of speeds for various vehicle types within the traffic stream. The second new approach, named the probabilistic approach, is concerned with using probabilities in estimating the PTSF. The need for this investigation has arisen from the concern that the current analytical procedures, namely the Highway Capacity Manual (HCM) 2000, provide erroneous results as suggested by previous research. The project reviews recent literature on the HCM procedures and evaluates their effectiveness using both theoretical and empirical analyses. Furthermore, the two new approaches were evaluated using empirical data from three study sites located throughout Montana's two-lane, two-way highway system.

This book was released on 1986 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes an investigation of potentially hazardous conditions at the upper end of climbing lanes on two-lane roads in Northern and Central California. It was postulated that, at such locations, there might be sideswipe accidents involving merging vehicles or head-on collisions of a vehicle swerving across the centerline to avoid such a sideswipe with a vehicle traveling in the opposite direction. Accident records covering five years at 21 potentially hazardous locations revealed that there are very few accidents directly related to the merging maneuver. Only 11 accidents at six locations were identified. The report suggests three guidelines for the location and design of climbing lanes to be considered in addition to those found in other literature. However, the general conclusion is that the merging areas at the terminals of climbing lanes on two-lane roads do not present a hazard of major proportions.
