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
Expressway Single-Lane Work Zone Capacities with Commercial Vehicle Impacts
Like other government transportation agencies, the Ontario Ministry of Transportation performs regular maintenance and reconstruction of freeways across the province. If lane closures are required for … [Read more...] about Expressway Single-Lane Work Zone Capacities with Commercial Vehicle Impacts
Microsimulation of Freeway Work Zones to Assess Flow and Capacity
This research applied microscopic traffic simulation to freeway work zones to further understand the relationship between traffic variables and capacity. There are two distinct forms of capacity … [Read more...] about Microsimulation of Freeway Work Zones to Assess Flow and Capacity
