WORK PLAN
cedar street ramp to interstate 93 Study
July 15, 2021
To be determined
Principal: Ed Bromage
Manager: Ben Dowling
Contract (to be determined)
Schedule and budget details are shown in Exhibits 1 and 2, respectively.
The City of Woburn is examining the possibility of adding a new ramp onto Interstate 93 from Cedar Street in Woburn. To support this analysis Woburn has asked CTPS to use its statewide travel demand forecasting model to analyze the interchange of Interstate 93 and Interstate 95 in Woburn under existing, future no-build, and future build conditions. Additionally, the client will also be examining a parallel corridor along Washington Street in Woburn between Mishawum Road and Montvale Avenue. A map of the study area is presented in Figure 1 below.

The objectives for this work plan are to provide the client with demand forecasts to support a traffic analysis for the project.
Central Transportation Planning Staff (CTPS) will support the client and its project team for the Cedar Street Ramp to Interstate 93 Project by providing data and analysis. The primary products CTPS will provide to the project team are highway assignment forecasts for a 2040 forecast year no-build and 2040 forecast year build scenario.
CTPS will work with the project team to help develop travel demand forecasts and respond to questions related to the tasks described below.
The travel demand model has been calibrated at the regional level and must be
reviewed, calibrated, and refined to best reflect the specific area being studied and to ensure reasonable sensitivity in the model to the proposed build scenario. CTPS will calibrate its model to a network area between Interstates 93 and 95 in Woburn using counts provided by the client’s consultant, World Tech Engineering, LLC. The client’s consultant will provide CTPS with counts for the AM and PM peak periods for all of the locations for which it seeks data from CTPS. The client anticipates needing data for approximately thirty locations. If data for significantly more than thirty locations are requested, a modification to this work plan may be required.
When the model has been updated with current traffic counts, CTPS will run the model iteratively to develop the best calibrated base year possible. CTPS will utilize a calibration technique known as Origin Destination Matrix Estimation to perform the calibration.
The calibrated model will be applied to develop baseline estimates of travel in the study corridor. CTPS will provide the client and its consultant with total vehicle volumes (not disaggregated by vehicle class) for the AM and PM peak periods.
After a calibrated base year has been developed, CTPS will carry the project specific calibration measures into future year 2040 model runs starting with a 2040 no-build model run which will be based upon the Boston Region Metropolitan Planning Organization’s current Long-Range Transportation Plan (LRTP) Build Scenario.
CTPS will model the implementation of the proposed Cedar Street ramp for a 2040 build scenario. At the request of the client, CTPS will also include in this build scenario one of the alternatives CTPS studied in the Low-Cost Improvements to Express-Highway Bottleneck Locations study from December 3, 2015.1 Note that the auxiliary lane described in that alternative is not a project in the current LRTP.
For the 2040 build scenario assignments, CTPS will use the same trip tables that were produced in the 2040 no-build scenario from Task 4. Using the same trip tables in the build scenario as were used in the no-build scenario will allow CTPS and the project team to isolate the effects of the differences between the no-build and build scenarios.
When the work for the project has been completed, CTPS will document its work in a technical memorandum.
1 In the 2040 build scenario CTPS will include Alternative 2 for Location 1 as described on page 12 of the December 3, 2015, memorandum.
