Risk Evaluation on Low Water‐Crossing Structures
(American Society of Civil Engineers, 1991)Highway engineers occasionally face the dilemma of either constructing a regular high bridge so that traffic would not be interrupted by floods or using a low water-crossing structure so that traffic would be interrupted ... -
Tire‐Wear Characteristics of Public Buses
(American Society of Civil Engineers, 1991)This paper describes a study that examines tire‐wear characteristics of a fleet of public buses under actual operating conditions. A sampling experiment is first performed to determine the number of tread‐depth measurements ... -
Nonparametric Regression and Short‐Term Freeway Traffic Forecasting
(American Society of Civil Engineers, 1991)After reviewing the problem of short‐term traffic forecasting a non‐parametric regression method, the -
Climatic Considerations in New AASHTO Flexible Pavement Design
(American Society of Civil Engineers, 1991)This research is undertaken to study and assess carefully the effect of climatic factors on the new American Association of State Highway and Transportation Officials (AASHTO) design for flexible pavements. Climatic factors ... -
Nonuniform Seismic Motion of Long‐Span Pipeline Suspension Bridges
(American Society of Civil Engineers, 1991)The goal of this investigation was to determine the responses of long‐span pipeline suspension bridges to nonuniform seismic motion. To achieve this objective, two existing bridges were analyzed: the 457.2 m Missouri River ... -
Optimization of AASHTO DNPS86 Pavement Design Program
(American Society of Civil Engineers, 1991)This paper describes an optimization program supplement to the DNPS86 pavement design computer program to produce a minimum‐cost combination of pavement layer thicknesses. The DNPS86 program has been made a subroutine of ... -
Characteristics of Fixed‐Roadside‐Object Side‐Impact Accidents
(American Society of Civil Engineers, 1991)Each year approximately 160,000 people are involved in accidents where the side of a vehicle strikes a fixed‐roadside object such as a tree, utility pole, or guardrail. Of these 160,000 occupants, 60,000 are injured and ... -
Evaluation of Errors in Automated Pavement‐Distress Data Acquisition
(American Society of Civil Engineers, 1991)The extent of degradation and decay of transportation infrastructure has created new demands on maintenance management systems. This, in turn, has emphasized the need for accurate condition assessment data for use in ... -
Realistic Simulation of Water Distribution System
(American Society of Civil Engineers, 1991)Due to financial constraints in developing countries, water supply to various consumers is quite less than actual demand. A technique for simulation of water distribution network duly considering this low supply situation ... -
Leak Location and Repair Cost for Underground Heat Distribution Systems
(American Society of Civil Engineers, 1991)The expected cost of leak location and repair is estimated for shallow trench and directly buried underground heat distribution systems. Leaks in shallow trench systems can be found during a visual search using a bisection ... -
Dynamic Scene Modeling for Automatic Traffic Data Extraction
(American Society of Civil Engineers, 1991)Motion analysis in a road scene from a sequence of T.V. images is the key problem for automatic data extraction. The task of estimating the motion parameters requires the computer to identify moving vehicles and pedestrians ... -
Dynamic Quality Control of Flexible Pavements
(American Society of Civil Engineers, 1991)A methodology is proposed to assure the final pavement structure under construction will meet the assumed design properties. Through a statistical analysis of the quality control data, for each layer, a check is made to ... -
Centralized Hub‐Terminal Geometric Concepts. I: Walking Distance
(American Society of Civil Engineers, 1991)This paper analyzes and compares several airport‐hub passenger‐terminal layouts in terms of average total walking distance. A second paper extends the results to include baggage‐handling operations. For the purposes of ... -

Truck Movement and Access in Urban Areas
(American Society of Civil Engineers, 1991)This paper discusses ways in which trucks may be specifically incorporated in the planning, design, and operation of urban traffic facilities. It is argued that if traffic engineers were to take greater and more explicit ... -
Evaluation of Outside and Inside Expressway Ramps Based on Merging Probability
(American Society of Civil Engineers, 1991)Japanese urban expressway networks contain not only the usual outside ramps, but also many inside ramps. Although the inside ramps do not block off adjacent and always‐expensive urban property, the design is less desirable ... -
Discussion of “<i>Analysis of Reinforced Concrete‐Pipe Performance Data</i>” by John C. Potter (September, 1988, Vol. 114, No. 5)
(American Society of Civil Engineers, 1991) -
Centralized Hub‐Terminal Geometric Concepts. II: Baggage and Extensions
(American Society of Civil Engineers, 1991)This paper shows how the geometric concepts examined in the first paper perform for baggage operations, recognizing that passengers and bags travel different distances through the airport. The paper shows that the most ... -
Dynamic Responses of Pipeline Suspension Bridges
(American Society of Civil Engineers, 1991)The objective of this engineering study is to determine the dynamic responses of pipeline suspension bridges. To this end, four existing pipeline suspension bridges are analyzed: the 259.2‐m Patterson Loop Aerial Crossing ... -
TEVACS: Decision Support System for Evacuation Planning in Taiwan
(American Society of Civil Engineers, 1990)A microcomputer‐based decision support system is developed for transportation network evacuation applications in Taiwan, the Republic of China. Input to the system mainly includes the trip‐generation‐related attributes, ...
