Traffic Simulation

The project aims to study ways to improve the Robertson / National on/off ramps and the connectors to local streets, simplify traffic movements and minimize traffic impacts from the Culver City Expo station and other new development in the area.

SR-55 is major north-south freeway corridor in Orange County, extending from the 19th St. intersection to the SR-91 interchange. Within the study corridor, there are a number of major freeway-to-freeway system interchanges, including SR-73, I-405, I-5, SR-91 and SR-22. The corridor has three to five mixed-flow lanes and one HOV lane with full-time continuous access along most sections. The corridor primarily consists of commuter traffic, and therefore, typical weekday morning and afternoon peak periods are of concern.

Microsimulation Plugins

As the major microsimulation plugin provider, CLR Analytics has developed a number of plugins under Paramics, TransModeler and Vissim. These plugins have been used by top simulation modeling consulting firms and some universities for various practical projects since Year 2008.

The study area for the SR-91 TSR extends from west of Tustin Avenue to east of Imperial Highway and includes SR-55 from the SR-91/SR-55 connector to south of Lincoln Avenue. There are four project alternatives for the build out year of 2025: No Build, Option 1A, Option 3, and Option 3L.

No-Build

The No-Build alternative or option incorporates funded projects that are currently being constructed or environmentally cleared as part of the Caltrans PSR-PDS.

The rapid development of automated vehicles has attracted a lot of attentions from the public in recent years.  Current studies on automated vehicles mainly focus on microscopic simulations with simple network topologies and driver behaviors, and few has considered to incorporate automated vehicles into macroscopic travel demand models for the analysis in a regional network.  

The Michael Baker International team, with SMG and CLR Analytics as a modeling and simulation subcontractor, won LADOT's I-10 Robertson National Circulation Improvement Project. CLR modelers will use travel demand modeling and traffic simulation tools to test different design scenarios for the project.
