Traffic Delays

 

User Costs as One of Main Advantages of Precast Concrete Application in Highway Construction

Road user cost primarily refer to the monetized components of road (re)construction impacts, such as the user delay costs, vehicle operating costs, crash costs and emission costs. Objective of this … [Read more...] about User Costs as One of Main Advantages of Precast Concrete Application in Highway Construction

Predicting Freeway Work Zone Delays and Costs with a Hybrid Machine-Learning Model

A hybrid machine-learning model, integrating an artificial neural network (ANN) and a support vector machine (SVM) model, is developed to predict spatiotemporal delays, subject to road geometry, … [Read more...] about Predicting Freeway Work Zone Delays and Costs with a Hybrid Machine-Learning Model

Work Zone Impact Assessment Methods and Applications

Two work zone impact assessment methods were developed and their applicability was illustrated with data from recent construction projects on the I-35 Central Texas corridor. The first method was … [Read more...] about Work Zone Impact Assessment Methods and Applications

Analysis of Loss of Time Value During Road Maintenance Project

Lane closure is frequently performed in the execution of the road maintenance project. It has a negative impact on road users such as the loss of vehicle operating costs and the loss of time value. … [Read more...] about Analysis of Loss of Time Value During Road Maintenance Project

Work Zone Traffic Management Analysis Using Analytical Methods

The course provides hands-on training on basic analytical methods (sketch planning methods) to compute work zone performance measures (WZPM). The WZPM includes the following factors: capacity, speed, … [Read more...] about Work Zone Traffic Management Analysis Using Analytical Methods

Data-Driven Traffic Impact Assessment Tool for Work Zones

Traditionally, traffic impacts of work zones have been assessed using planning software such as Quick Zone, custom spreadsheets, and others. These software programs generate delay, queuing, and other … [Read more...] about Data-Driven Traffic Impact Assessment Tool for Work Zones
