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
