Fundamental Insight into Signal Plan Transition Methods
Publisher: American Society of Civil Engineers
Abstract: This paper describes, in detail, the concrete operational mechanisms of the Corridor Simulation (CORSIM)–embedded signal transition algorithms. Through detailed analysis of these transition algorithms, this study found ...
Integrated Heteroscedasticity Test for Vehicular Traffic Condition Series
Publisher: American Society of Civil Engineers
Abstract: Because of the growing awareness of the importance of the traffic condition uncertainty-related studies, traffic condition uncertainty modeling is gaining increasing attention from the transportation research community. ...
Modeling and Forecasting Vehicular Traffic Flow as a Seasonal ARIMA Process: Theoretical Basis and Empirical Results
Publisher: American Society of Civil Engineers
Abstract: This article presents the theoretical basis for modeling univariate traffic condition data streams as seasonal autoregressive integrated moving average processes. This foundation rests on the Wold decomposition theorem and ...
Modeling Seasonal Heteroscedasticity in Vehicular Traffic Condition Series Using a Seasonal Adjustment Approach
Publisher: American Society of Civil Engineers
Abstract: Heteroscedasticity modeling in transportation engineering is primarily conducted in short-term traffic condition forecasting to generate time varying prediction intervals around the point forecasts through quantitatively ...
Improved Flow-Based Travel Time Estimation Method from Point Detector Data for Freeways
Publisher: American Society of Civil Engineers
Abstract: Travel time is an important parameter in evaluating the operating efficiency of traffic networks, in assessing the performance of traffic management strategies, and as input to many intelligent transportation systems ...
Simulation and Analysis of Freeway Lane Reversal for Coastal Hurricane Evacuation
Publisher: American Society of Civil Engineers
Abstract: Following the unprecedented multistate evacuation for Hurricane Floyd in 1999, the North Carolina Department of Transportation and the Department of Crime Control and Public Safety jointly developed a lane reversal plan ...
