Traffic Models

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

Modeling and Simulation of Traffic Flow in Work Zone on Highway

Behaviors of vehicles passing a work zone on two-lane highway are investigated. The traffic flow mathematical model is formulated based on optimal velocity model and safe lane-changing rules for … [Read more...] about Modeling and Simulation of Traffic Flow in Work Zone on Highway

Application of Visualization and Simulation Program to Improve Work Zone Safety and Mobility

A previous study sponsored by the Smart Work Zone Deployment Initiative, “Feasibility of Visualization and Simulation Applications to Improve Work Zone Safety and Mobility,” demonstrated the … [Read more...] about Application of Visualization and Simulation Program to Improve Work Zone Safety and Mobility

Replication of Work Zone Capacity Values in a Simulation Model

Evaluating the traffic impacts of work zones is vital for any transportation agency for planning and scheduling work activity. Traffic impacts can be estimated using microscopic simulation models. One … [Read more...] about Replication of Work Zone Capacity Values in a Simulation Model
