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

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
