3-C

Continuing, Cooperative, and Comprehensive: By Federal regulation the APO must follow a 3-C planning process.

ADT

Average Daily Traffic: The total number of vehicles that cross a specific point along a roadway over a number of days divided by the number of days. For example, a automated traffic counter might record the following daily traffic over three days: 10,000 on day 1; 12,000 on day 2; 8,000 on day 3. The ADT is calculated thus: 10,000+12,000+8,000=30,000/3 days=10,000 vehicles (on average) per day.

ALOP

Annual Listing of Obligated Projects: A status report on transportation projects for which funding was obligated in previous years.

APO

Saint Cloud Area Planning Organization: The organization designated by agreement between the Governor, local unit of government, and relevant agencies as being responsible for carrying out the terms of 23 USC Sec. 134. The APO is the Metropolitan Planning Organization (MPO) for the Saint Cloud urban area.

IIJA

The Infrastructure Investment & Jobs Act (public law 117-58) signed into law on Nov. 15, 2021. Part of the law establishes federal funding authorizations for surface transportation for the years 2022-2026.

MnDOT

Minnesota Department of Transportation: The State department with which the APO coordinates on transportation issues and which has oversight responsibilities for ensuring the APO complies with applicable Federal and State requirements.

MPA

Metropolitan Planning Area: The geographic area in which the APO carries out its planning activities. The MPA must include at least the US Census-defined urban area, but may also include any additional urban or urbanizing areas and/or commuter travel-sheds as deemed appropriate by the member jurisdictions of the APO.

MPCA

Minnesota Pollution Control Agency: The State agency responsible for monitoring environmental quality and enforcing environmental regulations in Minnesota.

MPO

Metropolitan Planning Organization: An organization designated by agreement between the Governor of a state, units of local governments of an urban area, and relevant agencies as being responsible for carrying out the terms of 23 USC Sec. 134. Any urban area of more than 50,000 people must have an MPO. As of 2015, there were 408 MPOs in the United States. The Saint Cloud APO is the MPO for the Saint Cloud metropolitan area.

MTP

Metropolitan Transportation Plan: The regional transportation plan with at least a 20 year planning horizon, developed cooperatively between the units of government and relevant agencies which are members of the APO.

RFP

Request for Proposals: This is a document used to procure consultant services. The RFP outlines the goals and objectives of a project or study and provides a not-to-exceed budget. Interested consultants then respond by writing and submitting a proposal to provide the required services.

SEP

Stakeholder Engagement Plan: The document that identifies when and how the APO will engage the public during the planning process. In Federal regulations, this document is called the "Public Participation Plan." The APO's SEP also includes our Title VI and Limited English Proficiency Plan.

SRTS

Safe Routes to School: A national initiative that works to make it safe, convenient, and fun for students to walk and bike to and from school.

STBGP

Surface Transportation Block Grant Program: Flexible funding from the Federal Government that may be used by states and localities for projects to preserve and improve the conditions and performance on any Federal-aid highway, bridge or tunnel project on any public road, pedestrian or bicycle infrastructure, and transit capital purchases, including intercity bus terminals.

TA

Transportation Alternatives: Funding from the Federal Government that may be used by state and localities for projects including, but not limited to, the creation of facilities for pedestrians and bicycles, environmental mitigation or habitat protection related to highway construction or operations, as well as infrastructure and non-infrastructure related to Safe Routes to School (SRTS) activities.

TAC

Technical Advisory Committee: The TAC is a committee of planners and engineers representing the local member governments and relevant agencies which is responsible for providing technical advice and guidance to the Policy Board and APO staff.

TAZ

Traffic Analysis Zone: A geographic area used in the Travel Demand Model (TDM). TAZs are assigned socio-economic attributes such as population, number of households, square feet of commercial space, and other data relevant to trip production or attraction.

TH

Trunk Highway: A major roadway connecting two or more cities that is operated and maintained by the State Department of Transportation and is the recommended or preferred route for long-distance and freight trips. In Minnesota, Trunk Highways are numbered, such as TH-15 or TH-23 and they may also be designated as MN-15 or MN-23.

TDM

Travel Demand Model: A computer model used to forecast traffic and traffic congestion under a variety of land use and roadway network conditions.

TPMR

Transportation Performance Monitoring Report: An annual report on how the transportation networks are functioning relative to the APO's adopted performance measures. The TPMR is a product of the APO's Transportation System Performance Monitoring (TSPM) program.

TIP

Transportation Improvement Program: The document that programs Federal funding for surface transportation projects within the MPA.

TSPM

Transportation System Performance Monitoring: An APO program in which staff collect and analyze transportation performance data in order to discover problem areas and help prioritize the programming of transportation improvement projects. The Transportation Performance Monitoring Report (TPMR) is a product of the TSPM.

UPWP

CURRENT UPWP   //  Travel Demand Model Improvements 2023

Travel Demand Model Improvements 2023

In 2020, the APO undertook an effort to significantly update and improve its Travel Demand Model (TDM), including building into the model updated algorithms and other improvements based on more state-of-the-art research and data regarding TDMs. As part of those updates, the model structure was altered to allow for time-of-day distribution of trips rather than just total daily trips. However, the budget at the time did not allow for the time-of-day distribution of trips to be fully implemented. Therefore, we are budgeting additional funds to

  1. fully implement the time-of-day distribution of trips, and
  2. Insert the necessary script to allow select-link analysis of model output.

Understanding how many trips use a particular corridor at specific times of day – such as the peak travel times – will allow the model to better inform corridor studies and lead to more efficient distribution of resources.

We expect the time-of-day distribution of trips within the model to be based on actual measured traffic volumes within the APO planning area. The current model will provide time-of-day traffic counts, but they are not actually calibrated to anything. We strongly prefer that the model output be based on measured, real-world data.

The APO does have access to Streetlight data and can provide data and information from Streetlight to the consultant for use in this effort.

The daily trip count model output should be the sum of the traffic counts from the various times of day.

The times of day used in the model can be grouped into logical bins, such as:

  • 6 am – 8 am
  • 8 am – 11 am
  • 11 am – 1 pm
  • 1 pm – 6 pm
  • 6 pm – 6 am

…or whatever bins seem most logical while still being insightful in a corridor study, understanding peak-hour traffic versus off-peak traffic, and as potential inputs into a microsimulation model.

If interested parties need access to our TDM files in order to ascertain the level of effort that would be needed to accomplish the goals of this proposal, you can send a request to gibson@stcloudapo.org.
