Congestion can restrict access to construction activities both on and close to a freeway, reducing construction efficiency, especially by delaying the delivery of materials. Although previous studies … [Read more...] about Modeling the Impact of Work-Zone Traffic Flows upon Concrete Construction: A High Level Architecture Based Simulation Framework

An Improved Cellular Automata Model for Heterogeneous Work Zone Traffic
This paper aims to develop an improved cellular automata (ICA) model for simulating heterogeneous traffic in work zones. The proposed ICA model includes the forwarding rules to update longitudinal … [Read more...] about An Improved Cellular Automata Model for Heterogeneous Work Zone Traffic
Evaluation and Implementation of Traffic Simulation Models for Work Zones
As the National Highway System reaches the end of its serviceable life, transportation agencies increasingly need to focus on the preservation, rehabilitation, and maintenance of these roads. In light … [Read more...] about Evaluation and Implementation of Traffic Simulation Models for Work Zones
Multivariate Regression for Estimating Driving Behavior Parameters in Work Zone Simulation to Replicate Field Capacities
Traffic simulation tools are being increasingly adopted by DOTs for various traffic analysis studies, including assessing work zone traffic impacts. This is due, in part, to their ability to model … [Read more...] about Multivariate Regression for Estimating Driving Behavior Parameters in Work Zone Simulation to Replicate Field Capacities
Optimal Work Zone Lengths and Signal Timing for Two-Lane Highways Revisited: The Need to Consider Stochasticity
Work zones can give rise to significant costs, both to maintenance agencies as well as to road users. In this paper we focus on the optimal configuration of work zones on two-lane highways. While … [Read more...] about Optimal Work Zone Lengths and Signal Timing for Two-Lane Highways Revisited: The Need to Consider Stochasticity
Modeling the Location of Crashes Within Work Zones: Methodology and a Case-Study Application
This study modeled the location of crashes within work zones as a function of the lengths of the different work zone segments, traffic volume, weather, and other exogenous factors. A multinomial-logit … [Read more...] about Modeling the Location of Crashes Within Work Zones: Methodology and a Case-Study Application
