Closure to “Review of Models Combining Traffic Assignment and Signal Control” by Claudio Meneguzzer
(American Society of Civil Engineers, 1998) -
Estimating Link Travel Time with the Mobilizer Video Image Tracking System
(American Society of Civil Engineers, 1999)Travel time is currently believed to be one of the best, if not the best, indicators of the quality of flow and operation on a transportation facility. Travel time is such a good measure because it is easy for both commuters ... -
System to Identify Turning Movements at Signalized Intersections
(American Society of Civil Engineers, 1998)A system to identify all left turns, through movements, and right turns at a signalized intersection is described. The complete system requires detection of vehicle departures from the intersection, right turn detection, ... -
Comparison of Failure Rates in Conduits for Underground Heat Distribution
(American Society of Civil Engineers, 1998)A survey of existing underground heat distribution systems was conducted to compare the failure characteristics of steel conduits with fiberglass reinforced plastic conduits. Pressure testing was carried out in order to ... -
Parameters Back-Calculation for Concrete Pavement with Two Slab Layers
(American Society of Civil Engineers, 1998)This paper presents a new procedure for back-calculating the properties of a concrete pavement with two slab layers using deflection measurements from nondestructive deflection testing. The two slab layers are first ... -
Analysis of Granular Bases Using Discrete Deformable Blocks
(American Society of Civil Engineers, 1998)A method of analysis using fully deformable blocks is proposed for modeling unbound granular layers used in flexible pavements. An assemblage of discrete blocks of aggregates is employed to approximate the load transfer ... -
New Model for Passing Sight Distance on Two-Lane Highways
(American Society of Civil Engineers, 1998)The maximum permitted length of trucks in North America and other parts of the world has increased significantly over the past 20 years. This has led to concern regarding the interaction of trucks with other elements in ... -
Comparison of Alternate Signal Timing Policies
(American Society of Civil Engineers, 1998)A signal timing policy describes operational goals applied when developing a timing plan for a system of coordinated intersections. This research investigates differences in signal timing plans resulting from implementation ... -
Permeability of Lime-Treated Lateritic Soil
(American Society of Civil Engineers, 1998)Laboratory investigations were carried out on a residual lateritic soil treated with quicklime (up to 8% by weight of dry soil) in order to evaluate the effect of lime content, curing period, and compactive effort on the ... -
<b><i>PRACTITIONER'S FORUM</i></b>: Limited-Stop Bus Service at New York City Transit
(American Society of Civil Engineers, 1998) -
Motor Vehicle Death Reductions from Guardrail Installation
(American Society of Civil Engineers, 1998)The effectiveness of guardrail installations and other road modifications to reduce injuries has been questioned recently based on critiques of study designs comparing injuries before and after installation at high risk ... -
Calibration of FRESIM for Singapore Expressway Using Genetic Algorithm
(American Society of Civil Engineers, 1998)FRESIM is a microscopic time-stepping simulation model for freeway corridor traffic operations. To enable FRESIM to realistically simulate expressway traffic flow in Singapore, parameters that govern the movement of vehicles ... -
Finite-Element Analyses of Flexible Pavements
(American Society of Civil Engineers, 1998)This study illustrates the usefulness of the finite-element method in the analysis of three-layer pavement systems subjected to different types of loading. The method is capable of simulating the observed responses of ... -
Full-Scale Accelerated Pavement Testing of Texas Mobile Load Simulator
(American Society of Civil Engineers, 1998)This paper presents the test results from full-scale accelerated pavement testing with the Texas Mobile Load Simulator. Data from in-situ instrumentation and nondestructive testing were collected and analyzed at different ... -
New Form of Road/Railway Transition Curve
(American Society of Civil Engineers, 1998)Road and railway transition curves have again become the subject of important scientific research and serious traffic engineering analyses because of high driving speeds and demands for automatic drive (i.e., car pilots). ... -
Neural Network Approach to Classification of Traffic Flow States
(American Society of Civil Engineers, 1998)The classification of traffic flow states in China has traditionally been based on the -
Predicting Vertical Dynamic Loads Caused by Vehicle-Pavement Interaction
(American Society of Civil Engineers, 1998)Dynamic loads caused by vehicle-pavement interaction are either moving loads or random loads. Motion property of dynamic loads was described by means of Dirac-delta and Heaviside functions, and its randomness property was ... -
Benchmarking for Design of Major Airports Worldwide
(American Society of Civil Engineers, 1998)This note presents, for the first time, the concept of benchmarking of airports from the perspective of designers and planners. Benchmarking is valuable for three reasons: it provides basic data otherwise difficult to ... -
Optimal Design of Public Bus Service with Demand Equilibrium
(American Society of Civil Engineers, 1998)Analytical models are developed to optimize bus service with their demand characteristics. The optimizing bus services design options are analyzed in this paper, while route spacing and headway are included with or without ... -
Evaluation of In-Situ Pavement Moduli Using High Resolution Tiltmeter
(American Society of Civil Engineers, 1998)This study presents a method of estimating the modulus of elasticity of an existing multilayer pavement system. The method is based on the interpretation of a measured deflection basin. The deflections of the existing ...
