Book Description
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.

Book Description
Under this research study, the effect of various delineation treatments on accident rates was assessed by analyzing accident data from more than 500 roadway sites in 10 States for tangent, winding and isolated horizontal curve sections on two-lane rural highways. Cost-benefit and cost models for evaluating specific delineation treatments were developed and guidelines formulated by executing the cost-benefit models for selected delineation treatments.

Book Description
This report is an Informational Guide for highway agencies on the use of low-cost improvements to alleviate operational problems on two-lane highways. The Guide addresses both passing and turning improvements that can be constructed for a lower cost than construction of a continuous four-lane highway. The passing improvements presented in the Guide include passing lanes, climbing lanes, short four-lane sections, turnouts, shoulder driving, and shoulder use sections. The turning improvements included are intersection turn lanes, shoulder bypass lanes, and two-way left-turn lanes. Design and traffic control guidelines presented for these improvements include location and configuration guidelines, geometric design criteria, recommended signing and marking practices, and operational and safety effectiveness estimates.

Book Description
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.
