Discussion of “<i>Are Pedestrians Safe at Right‐Turn‐on‐Red Intersections?</i>” by Himmat S. Chadda and Paul M. Schonfeld (January, 1985, Vol. 111, No. 1)
(American Society of Civil Engineers, 1987) -
Closure to “<i>Are Pedestrians Safe at Right‐Turn‐on‐Red Intersections?</i>” by Himmat S. Chadda and Paul M. Schonfeld (January, 1985, Vol. 111, No. 1)
(American Society of Civil Engineers, 1987) -
Probabilistic Approach to Consistency in Geometric Design
(American Society of Civil Engineers, 1987)The practice of evaluating consistency in geometric design is addressed. The current practice is based on comparing the speed of a certain percentile value at the points of interest. The underlying reasoning is to control ... -
Uncontrolled T Intersections: Who Should Yield?
(American Society of Civil Engineers, 1987)A questionnaire is distributed to licensed drivers in Iowa, asking questions regarding assignment of right‐of‐way at uncontrolled T intersections. A majority of respondents gives incorrect answers. Age is determined to be ... -
Urban Arterial Planning and Analysis
(American Society of Civil Engineers, 1987)Microcomputers and associated software are providing tremendous opportunities for the public works engineer in the analysis and evaluation of transportation projects. In particular, a wealth of software is available for ... -
Proper Determination of Earthworks Overhaul
(American Society of Civil Engineers, 1987)There is some lack of uniformity in determining earthworks overhaul distance. Often, it is calculated as the distance between the centers of gravity of the cut and the fill, less the freehaul distance. This paper describes ... -
Axisymmetric Slabs of Finite Extent on Elastic Solid
(American Society of Civil Engineers, 1987)The development of a computer program for the analysis of axisymmetric slabs of finite extent supported by an elastic solid foundation is described. CFES employs the method of concordant deflections and is much less taxing ... -
Environmental Planning in Urban Transportation
(American Society of Civil Engineers, 1987)Environmental analysis of transportation systems is a comprehensive and demanding task. The environmental planner is required to carefully and objectively examine project data provided by transportation planners and ... -
Longitudinal Stresses and Strains in Design of RPM Pipes
(American Society of Civil Engineers, 1987)Pipelines are subjected to variable support conditions in the longitudinal direction. These support conditions are encountered due to the variation in bedding and soil properties along the pipe, the geometry of the pipeline, ... -

Case for Variable Design Standards for Secondary Roads
(American Society of Civil Engineers, 1987)Work has been done to develop a rating system for priority planning use with secondary roads. A key constituent of the rating system is the design standard. It provides the basis for several rating criteria used to evaluate ... -
Closure to “NO2 <i>Exposure from Vehicles and Gas Stoves</i>” by Michael D. Rowe (November, 1985, Vol. 111, No. 6)
(American Society of Civil Engineers, 1987) -
Operational Feasibility of Timed Transfer in Transit Systems
(American Society of Civil Engineers, 1987)The concept of timed transfer, a scheduling procedure used in transit systems, is explained and examined. In particular, the feasibility of this procedure is evaluated using a simple two‐route case to determine the conditions ... -
Developing an Intersection Hazard Index
(American Society of Civil Engineers, 1987)A study was conducted: (1) To collect accident, environment, geometric and traffic flow data at rural three-leg wye intersections in West Virginia; (2) to identify any patterns linking accident data and intersection ... -
Discussion of “<i>Leakage from Ruptured Submarine Oil Pipelines</i>” by C. Kranenburg and E. Vegt (September, 1985, Vol. 111, No. 5)

Estimation of Mechanical Deterioration of Highway Rigid Pavements
(American Society of Civil Engineers, 1987)Highway rigid pavements, such as many of the constructed facilities of the nation, have been deteriorating, some even beyond functional failure, due to excessive loading, environmental effects, and chemical attack of the ... -
Expert System for Traffic Signal Setting Assistance
(American Society of Civil Engineers, 1987)An experimental knowledge‐based expert system to assist in traffic signal setting for isolated intersections is presented. In contrast to existing computer aids, the system can be applied to intersections of highly irregular ...
