Recent Projects

We assist many of our clients in a continuing capacity as existing and proposed land use and infrastructure conditions change.

We strongly believe in working as a team with our clients on all projects for maximum technology transfer and project benefit longevity.


New Mexico Statewide Travel Demand Model

New Mexico 2011-2012

ERMSI worked with the New Mexico Department of Transportation to update the New Mexico Statewide Travel Demand Model to provide forecasts for 2020 and 2030. This effort included review and revision of all procedures to provide statewide intercity and rural area forecasts for daily traffic and hourly volumes with dynamic assignment. Models and model data from Farmington MPO, Las Cruces MPO, Mid Region COG, Santa Fe MPO, El Paso MPO, and the cities of Alamogordo, Deming, Española, Gallup, Hobbs, Roswell, Silver City, and Taos have been integrated for model consistency and ease of updating. Special model tools were provided for subarea extraction and through trip reporting for use in the other models. Results were integrated into HERS-ST for statewide project and financial planning. Training was integrated into this project.

Santa Barbara County/Goleta, California

Model Plan Analysis 2012

Working with Associated Transportation Engineers, ERMSI updated the County of Santa Barbara’s model for the Goleta area. This included updating the calibration with updated traffic count, network, and land use data including recent development projects. Intersection geometrics were coded for key intersections and the traffic assignment was updated to use the coded numbers of turn lanes. Parcel level data was imported for allocation of growth to county traffic analysis zones. Forecasts are being provided using the proposed land use plan.

Yakima Valley Conference of Governments, Washington

Travel Model Update 2011-2012

Eco Resource Management Systems Inc. is providing on-call assistance and guidance as YVCOG updates its model for MPO planning. This model update includes revising the traffic analysis zone (TAZ) system, merging of the upper and lower valley models, revising land use and demographic inputs, adding transit and freight, and model recalibration. Current efforts include working with the MPO and member agencies to develop the model structure. Coordination with UW researchers to collect Truck O/D data is a part of this study. Previous efforts incorporated in this description include calibration of the YVCOG model and calibration of the Yakima County Model. Minor updates have been conducted for specific projects including network and TAZ updates and minor recalibration as needed.

Santa Fe, New Mexico

Model Update 2012-2013

ERMSI is working with the Santa Fe MPO staff to update and modernize the VISUM model for the Santa Fe MPO. This effort included updating the network to include intersection geometrics and other refinements, trip generation updates including changes to land use inputs, a more responsive transit element, automated traffic count updates, and other operational improvements. This project is in process.

Santa Fe, New Mexico

I-25/Cerrillos Road Interchange Interstate Access Change Request 2011-2012

Eco Resource Management Systems and Civil Transformations Inc. are providing traffic analysis as a part of the Molzen-Corbin and Associates led Interstate Access Change Request (IACR) project. ERMSI efforts include updating the Santa Fe MPO model with updated count and network data, adding detail for intersection geometrics and signalization for analysis and computation of delays, improving model feedback and reliability, and conducting LOS analysis and MOEs for all alternatives. Later stages of the project include integrating the VISUM model with VISSIM for more detailed analysis.

Santa Maria/Orcutt, California

Travel Demand Modeling Support 2006-2010, 2012

In conjunction with Associated Transportation Engineers, PTV America updated the model for the Santa Maria /Orcutt area. This included updating the calibration with updated traffic count, network, and land use data. Forecasts were tested for various growth scenarios including both land use and network revisions. Recent efforts by Eco Resource Management Systems Inc. (ERMSI) are to update the concurrency projects in the model for the analysis of development impacts.

Sunland Park, New Mexico

Port of Entry Application 2012

Eco Resource Management Systems is working with Molzen-Corbin and Associates and EnviroSystems Management Consultants on a Presidential Permit application for a new border crossing in Sunland Park, New Mexico. This effort involves providing traffic forecasts for private vehicles and pedestrians for alternative proposed border crossings. Included is traffic analysis for the border crossing processing and queues as well as for impacts to the surrounding transportation network. The traffic forecasting effort involves coordinating and combining data from models for El Paso, Juarez, and Las Cruces.

Rockford Metropolitan Area for Planning, Illinois

Freight Model Update 2008-2012

PTV America and Eco Resource Management Systems worked with AECOM to convert the TMODEL model to VISUM and enhance it with freight data. Freight is modelled by generating, distributing, and assigning truck trips as well as adding rail crossings and data for interaction with the vehicle network. This model encompasses 3 counties in Illinois and Wisconsin and comprises 680 zones. The model is being used for freight analysis as well as routine MPO traffic forecasts.

City of North Bend, Washington

Model Update 2011

Eco Resource Management Systems is working with Perteet, Inc. to update the transportation plan for the City of North Bend, WA. Efforts being conducted by ERMSI include translating the TMODEL model into VISUM, updating the calibration to 2011, and conducting forecasts for future scenarios. Detailed intersection geometries were coded to allow for rapid LOS analysis for comparison of future scenarios.

Bellevue, Washington

Central Business District Integrated Model 2006-2012

This project has been ongoing with many subproject portions to address and evaluate multiple analysis scenarios to assess the travel demand and corresponding operational impacts of future land use development on the access to and from the City of Bellevue. The City of Bellevue has experienced a major development boom in the past decade and has seen major increases in density in its downtown core and surrounding areas. A combination of VISUM and VISSIM has been used to test operational and other capacity improvements required to meet the concurrency regulations in the city as well as to evaluate other functionality. The existing Bellevue-Kirkland-Redmond (BKR) Travel demand model was the starting point for these projects. The entire model stream, from trip generation to mode choice, was converted from Emme2 into VISUM. Signal timing and lane configurations were imported from Synchro in order to perform intersection Level of Service (LOS) analysis in VISUM. Intersection geometrics were added to further improve the assignment before further analysis. Preliminary LOS was used to identify travel demand issues in the project area and to identify key improvements to be tested in VISSIM.
