HSR Cost Estimating Techniques in Pennsylvania
(American Society of Civil Engineers, 1989)Using a personal‐computer‐based spreadsheet program, costs are estimated by technology and by alignment segment to provide estimates of total costs and the basis for comparison of alternatives for high‐speed rail implementation. ... -
X‐Ray Imaging of Baggage for Agricultural Contraband
(American Society of Civil Engineers, 1988)Real‐time X‐ray inspection for agricultural contraband has been tested during unloading of checked airline bags on international flights. Selected flights were imaged during five weeks of peak travel at San Francisco ... -
Curing of Roller Compacted Concrete: Strength Development
(American Society of Civil Engineers, 1988)This paper reports on the strength development of three concrete mixes, with and without fly‐ash, subjected to many combinations of controlled moist and air‐dry environments during the first 27 days. Mix proportions and ... -
Pavement Problems Caused by Collapsible Subgrades
(American Society of Civil Engineers, 1988)Problem subgrade materials consisting of collapsible soils are common in arid environments, which have climatic conditions and depositional and weathering processes favorable to their formation. Included herein is a ... -
Walking Characteristics in Central Riydah, Saudi Arabia
(American Society of Civil Engineers, 1988)In recent decades, the importance of walking as a significant urban travel model in the total transportation system of an area has been recognized in the industrial nations of the West. In rapidly developing countries, ... -
Vehicle Behavior on Deceleration Lanes
(American Society of Civil Engineers, 1988)This paper presents an analysis and evaluation of vehicle flow characteristics on rural deceleration lanes. Site observations were conducted by means of video photography, tape‐switches for transmitting speed information, ... -
Merging Lane Length for Expressway Improvement Plan in Japan
(American Society of Civil Engineers, 1988)Expressway networks in large urban areas are often tied up with increasing traffic demands from many large commercial vehicles. These traffic conditions are preventing the expressway networks from their original function ... -
Technical Procedures for Interchange Justification
(American Society of Civil Engineers, 1988)Rapid land development and the lack of adequate local streets often results in requests for access to Interstate and other limited access highways. Gaining access to an Interstate highway is a highly valued asset and is ... -
Experimental Evaluation of Design Methods for Prestressed Concrete Plpe
(American Society of Civil Engineers, 1988)Tests conducted by the prestressed concrete pressure pipe industry in the United States during the past four decades have been gathered and analyzed. The present industry design procedures are summarized. Test results are ... -
Microwave Landing System Impact on Runway Capacity
(American Society of Civil Engineers, 1988)The microwave landing system (MLS) is scheduled to replace the existing instrument landing system as precision guidance for instrument operation by the turn of this century. This paper focuses on the impact of MLS on runway ... -
Analysis of Reinforced Concrete‐Pipe Performance Data
(American Society of Civil Engineers, 1988)Concrete pipes may be subject to deterioration from various conditions, including freeze‐thaw weathering, acid corrosion, sulfate disruption, velocity abrasion of the concrete, and chloride corrosion of the reinforcing ... -
Joint Shear Transfer Effects on Pavement Behavior
(American Society of Civil Engineers, 1988)This paper focuses on the relationship between shear transfer capabilities across pavement joints and the effects on the behavior of the pavement. The approach of the present study is to develop a numerical model that could ... -
Highway Routine Maintenance Programming at Network Level
(American Society of Civil Engineers, 1988)This paper describes a mathematical programming procedure for routine maintenance activities at the network level developed for incorporation into the existing pavement maintenance‐management system of Indiana. The procedure ... -
Adaptive Signal Control at Isolated Intersections
(American Society of Civil Engineers, 1988)The effectiveness of conventional traffic‐actuated control deteriorates rapidly as traffic volume increases. This problem can be alleviated through adaptive control. By monitoring vehicular movements and identifying the ... -
Method of Programming Regional Highway Projects
(American Society of Civil Engineers, 1988)This paper presents an integer programming formulation and heuristic solution procedure for programming regional highway projects. The objective is to determine an optimal program of projects over a multi‐period planning ... -
Optimum Stall Angle for Large Parking Lots
(American Society of Civil Engineers, 1988)A 90° angle for parking stalls relative to access aisles is usually recommended in the literature. This study reexamines the optimal parking angle using mathematical analysis and field tests. The area required per stall ... -
Erratum: “E' and Its Variation with Depth” by James D. Hartley and James M. Duncan (September, 1987, Vol. 113, No. 5)
(American Society of Civil Engineers, 1988) -
Improving Public Response to Sensitive Transportation Projects
(American Society of Civil Engineers, 1988)Among the most difficult challenges faced by transportation agencies in the last 25 years relates to informing the public so that opposition to proposed projects is kept to a minimum. This paper examines the methods used ... -
Dynamic Analysis of Lane Closure Strategies
(American Society of Civil Engineers, 1988)A dynamic simulation model is extended to represent traffic system disruptions in the form of lane closures. The model has two components: a macroparticle traffic simulator, and a user decisions component which comprises ... -
