Closure to “Impact Stops on Vehicle Fuel Consumption and Emissions” by Hesham Rakha and Yonglian Ding
Publisher: American Society of Civil Engineers
Integration Modeling Framework for Estimating Mobile Source Emissions
Publisher: American Society of Civil Engineers
Abstract: Transportation network improvements are commonly evaluated by estimating average speeds from a transportation/traffic model and converting them into emission estimates using an environmental model such as MOBILE or EMFAC. ...
Procedures for Calibrating TRANSYT Platoon Dispersion Model
Publisher: American Society of Civil Engineers
Abstract: The paper demonstrates some inherent limitations of the TRANSYT software with regard to calibration of the recursive platoon dispersion model and, more specifically, modification of the travel time factor. Subsequently, ...
Variable Power Vehicle Dynamics Model for Estimating Truck Accelerations
Publisher: American Society of Civil Engineers
Abstract: This paper introduces the concept of a linearly increasing variable power to the basic vehicle dynamics model that has been proposed in the literature. The paper also calibrates the model to typical truck classifications ...
Analytical Procedures for Estimating Capacity of Freeway Weaving, Merge, and Diverge Sections
Publisher: American Society of Civil Engineers
Abstract: The paper identifies a total of 34 different weaving section configurations that are modeled while operating at capacity using the INTEGRATION software for a wide range of weaving section lengths and travel demand ...
Impact of Stops on Vehicle Fuel Consumption and Emissions
Publisher: American Society of Civil Engineers
Abstract: 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 ...
Issues and Solutions to Macroscopic Traffic Dispersion Modeling
Publisher: American Society of Civil Engineers
Abstract: The paper improves upon the Yu and Van Aerde calibration procedure of the TRANSYT-7F platoon dispersion model, particularly for time steps greater than 1 s in duration, and develops three generalized platoon dispersion ...
Closure to “Estimating Vehicle Fuel Consumption and Emissions based on Instantaneous Speed and Acceleration Levels” by Kyoung Ahn, Hesham Rakha, Antonio Trani, and Michel Van Aerde
Publisher: American Society of Civil Engineers
Truck Performance Curves Reflective of Truck and Pavement Characteristics
Publisher: American Society of Civil Engineers
Abstract: The paper utilizes a linearly increasing variable power vehicle dynamics model to develop the
Sensitivity Analysis of Transit Signal Priority Impacts on Operation of a Signalized Intersection
Publisher: American Society of Civil Engineers
Abstract: The study consists of a systematic simulation evaluation of transit signal priority (TSP) impacts on the operations of a single signalized intersection within a coordinated arterial system. The study demonstrates first ...
