Comparative Assessment of Geospatial and Statistical Methods to Estimate Local Road Annual Average Daily Traffic
(ASCE, 7/1/2021)Collecting traffic data and/or estimating and reporting annual average daily traffic (AADT) is important for planning, designing, building, and maintaining the road infrastructure. However, AADT is not available for most ... -
Exploring Maximum and Minimum Operating Speed Positions on Road Geometric Elements Using Continuous Speed Data
(ASCE, 8/1/2021)Speed prediction models are commonly developed using maximum and minimum operating speeds measured at or within specific locations on the tangents and horizontal curves, respectively. However, the actual distribution of ... -
Reexamining Pedestrian Crossing Warrants based on Vehicular Delay at Urban Arterial Midblock Sections under Mixed Traffic Conditions
(ASCE, 8/1/2021)Pedestrian crossing activity at unmarked crosswalks on urban roads in developing countries like India is a common phenomenon. Pedestrians used to cross the road at their place of interest to access residential and commercial ... -
Social Impact Analysis of Various Road Capacity Expansion Options: A Case of Managed Highway Lanes
(ASCE, 7/1/2021)Managed lanes (MLs) offer public infrastructure owners a key policy lever for reducing the financial burden of road expansion while managing induced travel demand. ML’s impact varies depending on the operational method ... -
Estimation of Transfer Time Distribution Parameters with Automatic Fare Collection Data: Stochastic Frontier Model
(ASCE, 7/1/2021)The uncertainty in walking and waiting transfer times at transit stops depends on the environmental conditions, vehicle schedule punctuality, and variations among individuals. Relying only on the mean values ignores such ... -
Preliminary Safety Evaluation of Self-Driving, Low-Speed Shuttle
(ASCE, 8/1/2021)Although fully implemented autonomous vehicles (AVs) seem to be on the cusp of reality, standard evaluation and testing procedures still are lacking. This study conducted a preliminary evaluation of the technical feasibility, ... -
Matching Model between Private Idle Parking Slots and Demanders for Parking Slot Sharing
(ASCE, 6/1/2021)A two-stage method for matching private idle parking slots with demanders is proposed based on the core idea of private idle parking slot sharing to solve the problem of parking difficulty in a shared economy environment. ... -
Congestion Index and Reliability-Based Freeway Level of Service
(ASCE, 6/1/2021)Examining the relationship between congestion and travel time reliability (TTR) can help in gaining a broader perspective on the development of congestion mitigation strategies. Several performance measures have been ... -
Characterizing Heterogeneity among Merging Positions: Comparison Study between Random Parameter and Latent Class Accelerated Hazard Model
(ASCE, 6/1/2021)This study aims to build an accurate merging position model by incorporating heterogeneity into the accelerated hazard model based on random parameter and latent class models. Three kinds of distribution (Weibull, log-normal, ... -
Quantifying the Relative Influence of Railway Hump Classification Yard Performance Factors
(ASCE, 8/1/2021)Single-railcar freight shipments that move in multiple freight trains and are sorted at several classification yards between origin and destination remain an important source of traffic and revenue for North American ... -
Multistate Assessment of Roadway Travel, Social Separation, and COVID-19 Cases
(ASCE, 5/1/2021)This research was undertaken to comparatively assess the unprecedented travel and activity conditions related to the onset of coronavirus disease of 2019 (COVID-19) in the US in the first half of 2020. In this effort, ... -
Quantifying the Traffic Impacts of the COVID-19 Shutdown
(ASCE, 5/1/2021)The coronavirus disease (COVID-19) pandemic has significantly disrupted transportation and travel patterns across the US and around the world. A significant driving factor in the significant reduction in travel in the US ... -
Impact of Optimal Selection of Merging Position on Fuel Consumption at Highway On-Ramps
(ASCE, 5/1/2021)In recent years, there have been research efforts to develop intelligent control approaches for connected and automated vehicles (CAVs) at merging highways to reduce traffic jams and the consumption of fuel. This paper ... -
Modeling Violation Behavior at Highway-Rail Grade Crossings Using a Driver Anxiety Surrogate Measure
(ASCE, 6/1/2021)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 ... -
Operating Speed Modeling for the Rural Highways Passing through Hilly Terrain
(ASCE, 5/1/2021)The operating speed model (OSM) is essential for geometric consistency analyses, but the formulation of OSMs for a complicated highway geometry is a challenging task. Highways passing through hilly terrain consist of a few ... -
Safety Evaluation of High-Occupancy Toll Facilities Using Bayesian Networks
(ASCE, 5/1/2021)High-occupancy toll (HOT) lanes have increasingly been adopted as a strategy to reduce congestion. While numerous studies have focused on the operations of HOT facilities, little is known about their safety performance. ... -
Spatiotemporal Deep-Learning Networks for Shared-Parking Demand Prediction
(ASCE, 6/1/2021)One fundamental issue in managing a shared-parking system is predicting shared-parking demand. Such predictions are very challenging because predicting shared-parking demand usually involves nonlinearities and complex ... -
