Urban Trees and Roadside Safety
(American Society of Civil Engineers, 1990)This paper describes a research project performed as part of a clear zone implementation program for Huntsville, Alabama. A literature review and a field investigation program were the two major components of the project. ... -
Flattening of Horizontal Curves on Rural Two‐Lane Highways
(American Society of Civil Engineers, 1990)Current practices in resurfacing, restoration, and rehabilitation of highways generally emphasize lane‐ and shoulder‐width improvements. These practices neglect the possibility that flattening curves by reducing curvature ... -
Aluminum‐Coated Corrugated Steel‐Pipe Field Performance
(American Society of Civil Engineers, 1990)The design life used by many agencies for planning drainage structures has increased to 50 years or more in recent years. This has created a niche for a more durable product in the low‐cost market. Aluminum‐coated corrugated ... -
Travel Impact Evaluation for Major Highway Reconstruction Projects
(American Society of Civil Engineers, 1990)A key issue in planning major highway reconstruction projects is the allocation of roadway space between the reconstruction activities and the motorists. Estimates of the travel impacts of alternative allocations are ... -
Field Test of Catenary Net to Protect Traffic from Mining Subsidence
(American Society of Civil Engineers, 1990)It is often necessary to construct roads across areas that have been undermined at shallow depth or that are subject to surface subsidence from other causes. Surface subsidences can be bridged by incorporating a continuous ... -
Reviewers of the <i>Journal of Transportation Engineering</i>
(American Society of Civil Engineers, 1990) -
Scheduling Method for Demand‐Responsive Transportation System
(American Society of Civil Engineers, 1989)This paper offers an addition to a family of previously proposed vehicle‐scheduling models for a demand‐responsive transportation system. The assumed operating environment consists of many‐to‐many travel demand, multi‐vehicle, ... -
Dimensional Analysis in NDT Rigid Pavement Evaluation
(American Society of Civil Engineers, 1990)A consistent and theoretically rigorous approach is presented, using the principles of dimensional analysis, and leading to a closed‐form back‐calculation procedure for a two‐layer slab‐on‐grade pavement system. The equations ... -
Critical Issues in Safe Transport of Hazardous Materials
(American Society of Civil Engineers, 1989)The growing volume of hazardous‐materials shipments and the potential consequences of a materials release have raised public concern and scrutiny over the safe handling and transport of hazardous cargo. This has prompted ... -
Hubbing and Airline Costs
(American Society of Civil Engineers, 1989)Airline hubbing can be viewed as a strategy to increase airline network efficiency and to reduce operating costs. Alternatively, hubbing can be viewed as a marketing strategy permitting airlines to achieve dominant market ... -
Evaluation of Admixture Stabilization for Problem Laterite
(American Society of Civil Engineers, 1989)The paper presents results of research carried out to evolve suitable evaluation criteria for admixture stabilization for problem laterite where Portland cement is used as the stabilizer and hydrated lime as the admixture. ... -
Multi‐Objective Programming Approach for Routing Hazardous Materials
(American Society of Civil Engineers, 1989)This paper examines the systemwide routing, of hazardous materials as a means of reducing the threat to the population residing along the links of an entire transportation network. A multi‐objective decision‐making model ... -
Successful Siting of Airports: Sydney Example
(American Society of Civil Engineers, 1990)A procedure for siting major new airports is proposed and validated by example of its successful use in Australia to obtain agreement on the location of the second Sydney airport. The technique differs from the traditional ... -
Safety of High‐Occupancy Vehicle Lanes Without Physical Separation
(American Society of Civil Engineers, 1989)This study addresses safety issues associated with the operation of freeway high‐occupancy vehicle (HOV) lanes that are not separated by physical barriers from adjacent, general‐purpose traffic lanes. Accident frequencies ... -
Large‐Truck Properties and Highway Design Criteria
(American Society of Civil Engineers, 1990)Substantial increases in truck weights and dimensions have occurred over the past decade and these changes have important implications for the criteria used for the design of various components of highway infrastructure. ... -
Prediction of Design Hourly Volume from Road Users' Perspective
(American Society of Civil Engineers, 1989)The present investigation considers the prediction of the design hour volume from users' perspective. [The design hour volume concept from users' perspective was introduced in an earlier paper (Sharma 1986), which concluded ... -
Short‐Term Demand for Specialized Transportation: Time‐Series Model
(American Society of Civil Engineers, 1990)This paper focuses on regression and intervention modeling of Lexington/Fayette County specialized transportation, WHEELS, monthly riderships. The 1979–1985 time‐series ridership data are comprised of total monthly trips ... -
Discussion of “<i>E' and Its Variation with Depth</i>” by James D. Hartley and James M. Duncan (September, 1987, Vol. 113, No. 5)
(American Society of Civil Engineers, 1989) -
General Aviation Collision‐Avoidance Alternatives
(American Society of Civil Engineers, 1989)Midair collisions are often perceived as the number‐one safety issue in aviation. Though the actual incidence of such accidents is (thankfully) small, public perception of the problem, and the government's reaction to it, ... -
Loads on Rigid Box Buried in Nonlinear Medium
(American Society of Civil Engineers, 1989)The relative settlement of a rigid box buried in a nonlinear medium is simulated by the trapdoor model. The nonlinear compressibility and shear‐displacement relationships are idealized by piecewise linear curves for which ...
