RISSpatial Interpolation–Based Localized Growth Factors Compared to Statewide, Regional-Level, and County-Level Growth Factors for Local Roads
Publisher: ASCE
Abstract: The focus of this paper is on developing localized growth factors for estimating annual average daily traffic (AADT) of a local, functionally classified road (referred to herein as a local road). Statewide, regional-level, ...
Comparative Assessment of Geospatial and Statistical Methods to Estimate Local Road Annual Average Daily Traffic
Publisher: ASCE
Abstract: 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 ...
Average Travel Time, Planning Time Index, and Buffer Time Index Thresholds for Freeway Weaving Sections, Merging Areas, and Diverging Areas
Publisher: ASCE
Abstract: Efforts were initiated through the Strategic Highway Research Program (SHRP) to quantify level of service (LOS) based on travel time and travel time reliability. To contribute to this goal, this study adopted a microscopic ...
Assessment of Link Reliability as a Function of Congestion Components
Publisher: American Society of Civil Engineers
Abstract: Travelers’ perception of reliability of a road network is typically based on factors contributing to both recurring and nonrecurring congestion. However, literature documents little research to integrate, estimate and ...
Spatial Proximity and Dependency to Model Urban Travel Demand
Publisher: American Society of Civil Engineers
Abstract: Link level annual average daily traffic (AADT) or travel demand is used in several urban planning, roadway design, operational, and safety analyses by transportation planners and engineers. Existing AADT estimation methods ...
Using Genetic Algorithms to Evaluate Aircraft Ground Holding Policy in Real Time
Publisher: American Society of Civil Engineers
Abstract: Ground holding policy (GHP) offers a potential solution to alleviate increasing congestion problems in the air transportation network. The policy proposes to hold an aircraft before takeoff so that when it arrives at its ...
Spatial Proximity and Dependency to Model Urban Travel Demand
Publisher: American Society of Civil Engineers
Abstract: Link level annual average daily traffic (AADT) or travel demand is used in several urban planning, roadway design, operational, and safety analyses by transportation planners and engineers. Existing AADT estimation methods ...
Using Genetic Algorithms to Evaluate Aircraft Ground Holding Policy under Static Conditions
Publisher: American Society of Civil Engineers
Abstract: The U.S. airline industry is facing delays due to congestion problems in the air transportation network. These delays not only lead to increased costs, but they also have safety related implications. Some of the costs ...
Modeling Link-Level Crash Frequency Using Integrated Geospatial Land Use Data and On-Network Characteristics
Publisher: American Society of Civil Engineers
Abstract: The primary focus of this paper is to develop models to estimate link-level crash frequency using land use data extracted and integrated through the use of a distance gradient method. The on-network characteristics were ...
Principle of Demographic Gravitation to Estimate Annual Average Daily Traffic: Comparison of Statistical and Neural Network Models
Publisher: American Society of Civil Engineers
Abstract: This paper focuses on the application of the principle of demographic gravitation to estimate link-level annual average daily traffic (AADT) based on land-use characteristics. According to the principle, the effect of a ...
