RISHolistic Framework for Highway Construction Cost Index Development Based on Inconsistent Pay Items
Publisher: ASCE
Abstract: A construction cost index (CCI) measures the price changes of construction items over time. It allows owner agencies and contractors to monitor construction market fluctuations so that they can more accurately estimate ...
Comparison of Methods for Defining Geographical Connectivity for Variables of Trip Generation Models
Publisher: American Society of Civil Engineers
Abstract: The four-step procedure for travel demand modeling is ubiquitously used in the United States and elsewhere due to institutional and financial requirements. Trip generation analysis, which is the first step, is based on ...
Probabilistic Neural Networks Application for Vehicle Classification
Publisher: American Society of Civil Engineers
Abstract: Federal, state, and local agencies use vehicle classification data for planning, design, and conducting safety and operational evaluation of highway facilities. In conformity with federal reporting requirements, most states ...
Modeling Signalized-Intersection Safety with Corner Clearance
Publisher: American Society of Civil Engineers
Abstract: Signalized intersections next to each other on the same arterial share some unobservable information, such as traffic flow and roadway characteristics. This study investigated the impact of access management techniques on ...
Robust Forecasting Models for Highway Construction Cost Indices during Pandemic-Era Inflation
Publisher: American Society of Civil Engineers
Abstract: The highway construction cost index (HCCI) is a critical benchmark for managing highway construction project budgets. However, unpredictable economic and market changes, such as inflation due to the pandemic and supply ...
Modeling Dynamics of Vehicle-Based Performance Measures of High-Occupancy Vehicle and General-Purpose Traffic Systems
Publisher: American Society of Civil Engineers
Abstract: This study aimed at modeling dynamics of traffic systems with integrated and cointegrated stochastic processes using multiple time series of traffic flows generated by general purpose (GP) and high-occupancy vehicle (HOV) ...
Estimating Highway Capacity Considering Two-Regime Models
Publisher: American Society of Civil Engineers
Abstract: Capacity can be derived by fitting a relationship between the three fundamental traffic variables: flow, speed, and density. The study uses a dual-regime model with the consideration of all three variables. Different forms ...
Semantic N-Gram Feature Analysis and Machine Learning–Based Classification of Drivers’ Hazardous Actions at Signal-Controlled Intersections
Publisher: ASCE
Abstract: In the United States, it is common for crash reports to include a narrative that contains a police officer’s written summary of the crash. The crash narratives provide valuable information that can assist in understanding ...
Applying Probabilistic Model to Quantify Influence of Rainy Weather on Stochastic and Dynamic Transition of Traffic Conditions
Publisher: American Society of Civil Engineers
Abstract: This study used a time-varying Markov chain (TMC) assumption to develop an empirical probabilistic model that evaluates the influence of rainy weather and traffic volume on the dynamic transition of traffic conditions. The ...
