Book Description
This Circular contains 23 research problem statements, nine of which were developed by TRB Committee A3A08, "Operational Effects of Geometrics," and the remainder by TRB Committee A2A02, "Geometric Design." The statements are rated as highest priority, high priority, and additional problem statements. The highest and high priority statements contain the following: title, problem statement, research objectives, key words, related work, urgency/priority, estimated cost, user community, implementation, and effectiveness. Additional statements contain only a title, problem statement, and research objectives.

Book Description
This circular lists the problems selected by the TRB Committee on Operational Effects of Geometrics (A3A08) in 1985 as most worthy of future research. They are (in order of priority): influence of approach geometry on effectiveness of countermeasures at high-speed signalized intersections, guidelines for design of rural intersections, geometric design consistency for range of vehicle types, selection of design vehicle for geometric design of at-grade intersections, the use of shoulders as continuous turnouts on rural two-lane highways, determination of the operational and safety benefits of spiral transitions, geometrics for large trucks and small cars, high volume merges for low-performance cars, and optimum sidewalk width.

Book Description
Nine research problem statements considered by the TRB Committee A3A08. Operational Effects of Geometrics, are presented. Each statement identifies the problem, describes the objective of the research, notes related work, and indicates the urgency for the study, and the projected costs. The principal users of the research findings are also noted. The implementation of the findings and possible effectiveness are discussed. The research problems are as follows: warrants for left-turn lanes; warrants and Guidelines for Continuous Exclusive Right-Turn Lanes; Relationship of Stopping Sight Distance to Clearance Times at Stop Sign Controlled Intersections; Coordinating Design, Operating, and Posted Speeds; Increasing Roadway Geometric Delineation when Reducing Highway Illumination; Operational or Geometric Countermeasures for Reducing Run-Off-Road Accidents on Rural Horizontal Curves; Analysis of Rural Highway Alignments Prone to Increased Accident Rates; Optimum Selection of Access Locations Along Major Arterials; and Raised Medians--A Poor Substitute for Good Access Control.
