RISImpact of CAV Truck Platooning on HCM-6 Capacity and Passenger Car Equivalent Values
Publisher: ASCE
Abstract: Recently, there has been a significant amount of research related to heavy trucks operating as connected and autonomous vehicles (CAVs). As argued in this paper, to understand the potential impact on the freeway system of ...
Modeling Violation Behavior at Highway-Rail Grade Crossings Using a Driver Anxiety Surrogate Measure
Publisher: ASCE
Abstract: When responding to changes in the status of traffic controls, drivers may experience uncertainties caused by incomplete and inaccurate information. These uncertainties may result in driver anxiety during the decision-making ...

System Wide Data Quality Control of Inductance Loop Data Using Nonlinear Optimization
Publisher: American Society of Civil Engineers
Abstract: One of the main criticisms and concerns over the years about inductive loop detector (ILD) data is systematic errors in the data associated with noncatastrophic malfunctioning of the devices. Most of the current approaches ...
Improved Transition Preemption Strategy for Signalized Intersections near At-Grade Railway Grade Crossing
Publisher: American Society of Civil Engineers
Abstract: Because the prime objective of the current preemption methods for traffic signals located near highway-railroad grade crossings is to clear vehicles from the crossing, secondary objectives such as maximizing pedestrian ...
Equitable Traffic Assignment with Environmental Cost Functions
Publisher: American Society of Civil Engineers
Abstract: In the past 10 years increased importance has been placed on public participation and environmental concerns in transportation system decision-making. While there are numerous societal objectives to consider when planning ...
Spectral Basis Neural Networks for Real-Time Travel Time Forecasting
Publisher: American Society of Civil Engineers
Abstract: This paper examines how real-time information gathered as part of intelligent transportation systems can be used to predict link travel times for one through five time periods ahead (of 5-min duration). The study employed ...
Proposed Equations for HCM-6 Passenger Car Equivalent Values
Publisher: ASCE
Abstract: In the current version of the Highway Capacity Manual (HCM-6), the equal capacity passenger car equivalency (EC-PCE) method is used to account for the effect of trucks for capacity analyses. The EC-PCEs for freeway segments ...
Impact of Capacity Definition on the HCM-6 Passenger Car Equivalent Values
Publisher: ASCE
Abstract: In the current version (Version 6) of the Highway Capacity Manual (HCM), equal-capacity passenger car equivalencies (EC-PCEs) are used to account for the effect of trucks for capacity analyses. The EC-PCEs for freeway ...
Arterial Roadway Travel Time Reliability and the COVID-19 Pandemic
Publisher: ASCE
Abstract: This paper evaluated the effect of the COVID-19 preventive orders on arterial roadway travel time reliability (TTR). A comparative analysis was conducted to examine average travel time distributions (TTD), and their ...
