Discussion of “Model for Determining Optimum Bus-Stop Spacing in Urban Areas” by Anthony A. Saka
(American Society of Civil Engineers, 2002) -
Consideration of Fractals Potential in Pavement Skid Resistance Evaluation
(American Society of Civil Engineers, 2002)Pavement surface texture greatly contributes to tire-pavement skid resistance. Pavement surface irregularities are continuous from pavement macrotexture to pavement microtexture. Their pattern is also roughly repetitive. ... -
On-Line Measure of Shockwaves for ITS Applications
(American Society of Civil Engineers, 2003)The formation of shockwaves demarking boundaries between different flow states in time-space domains has been well studied and documented in the literature. Previous research concentrated on theoretical and mathematical ... -
Impact of Stops on Vehicle Fuel Consumption and Emissions
(American Society of Civil Engineers, 2003)Macroscopic emission models use average speed as a sole traffic-related explanatory variable. Research, however, has demonstrated that the use of average speed as a single traffic-related explanatory variable is insufficient ... -
Evaluation of Low-Temperature Properties of HMA Mixtures
(American Society of Civil Engineers, 2002)The deterioration of flexible pavements due to low-temperature cracking is a significant and costly problem in the state of Nevada. The Nevada Department of Transportation initiated several research efforts aimed at exploring ... -
Modeling Duration of Urban Traffic Congestion
(American Society of Civil Engineers, 2002)Research on short-term traffic conditions prediction has been largely concerned with parameters such as flow, occupancy, and speed, ignoring at the same time predictions during congestion, a period when predictions are ... -
Closure to “Model for Determining Optimum Bus-Stop Spacing in Urban Areas” by Anthony A. Saka
(American Society of Civil Engineers, 2002) -
Falling Weight Deflectometer for Estimating Subgrade Elastic Moduli
(American Society of Civil Engineers, 2003)Subgrade soil characterization in terms of resilient modulus -
Causal Relationship Among Travel Mode, Activity, and Travel Patterns
(American Society of Civil Engineers, 2003)Simple or complex travel patterns, performed as activities, are linked, and various travel modes are used. Individuals try to link several trips as a type of chain to save transportation resources, such as travel distance ... -

Fast Automatic Incident Detection on Urban and Rural Freeways Using Wavelet Energy Algorithm
(American Society of Civil Engineers, 2003)A comprehensive evaluation is presented of the single-station wavelet energy neural network freeway incident-detection algorithm of Karim and Adeli. Quantitative performance measures of detection rate, false alarm rate, ... -
Criteria-Based Decision Support System for Selecting Highway Alignments
(American Society of Civil Engineers, 2003)At the planning stages of a highway development process a number of candidate highway alignments are explored. While computerized highway optimization models can seek optimized horizontal and vertical alignments by minimizing ... -
Comparing Driver Information Systems in a Dynamic Modeling Framework
(American Society of Civil Engineers, 2003)A modeling framework is developed to assess the performance of driver information systems. The two main components of the framework are a route choice module and a traffic simulation module. In the route choice module, ... -
Two-Phase Fluids Model for Freeway Traffic Flow and Its Application to Simulate Evolution of Solitons in Traffic
(American Society of Civil Engineers, 2003)A two-phase fluids model for mixing traffic flow on freeways has been proposed, where vehicles are decomposed into two parts (i.e., phases)—slow moving and fast moving–denoted by subscripts -
Single-Event Cracking Temperature of Asphalt Pavements Directly from Bending Beam Rheometer Data
(American Society of Civil Engineers, 2002)Asphalt pavements under low temperature conditions develop transverse cracks as a result of one or a combination of three distress mechanisms: (1) single-event thermal cracking; (2) thermal fatigue; and (3) load-associated ... -
Optimal Allocation of Resources To Meet Transit Fleet Requirements
(American Society of Civil Engineers, 2002)A two-stage procedure to optimally allocate limited resources for the dual purpose of purchasing new transit buses and rebuilding existing buses is presented in this paper. In stage 1, estimates are derived for the maximum ... -
Rational Method for Selecting Seismic Waves for Pavement Evaluation
(American Society of Civil Engineers, 2002)The precision of pavement moduli values is affected by the selection process of the signals from the seismic pavement analyzer (SPA). If improper signals were selected, moduli values from the SPA were lower than those ... -
Speed Bumps May Induce Improper Drivers’ Behavior: Case Study in Italy
(American Society of Civil Engineers, 2002)Many studies conducted over the last 20 years show that speed bumps have only a limited affect in decreasing traffic speed, especially compared to better designed passive speed control devices, such as speed humps or ... -
Probabilistic Segment-linked Pavement Management Optimization Model
(American Society of Civil Engineers, 2002)Pavement management systems (PMSs) are increasingly important tools in the decision-making processes regarding the maintenance and rehabilitation of road pavements. A new optimization model to be used within network-level ... -
Performance Evaluation of Short-Term Time-Series Traffic Prediction Model
(American Society of Civil Engineers, 2002)One of the key functions of an effective Advanced Traveler and Management Information System is the ability to model short-term predictions of traffic conditions on major freeways and arterials with reasonable accuracy. ...
