The main purpose of a Traffic Impact Study (TIS) is to demonstrate how the transportation impacts of a proposed development or redevelopment can be mitigated and addressed in a manner that is consistent with the objectives of the Ministry of Transportation. The TIS also serves as the basis for the identification and evaluation of transportation related improvements or measures to be included as a condition of access approval for the development or redevelopment.
Evaluation of traffic impacts of proposed development depends upon a number of assumptions about the type, amount and patterns of traffic expected to be produced from and attracted to the site. MTO staff are available for pre-submission communication to confirm key assumptions and parameters through the Regional Planning and Design Section (referred to as Corridor Management office in Central Region only). Depending upon the complexity of the proposed development, this may reduce or negate the need for study revisions following submission of the completed study. A list of possible discussion items is attached for reference.
For clarification on any matters related to the submission, contact the appropriate Regional Planning and Design Section (Corridor Management Section in Central Region only) provided below. For services in French, contact HSBTrafficOffice@ontario.ca.

MTO will accept the use of Highway Capacity Software (HCS) 2000 and Synchro/Sim Traffic Simulation Software Version 5 (or higher) for intersection capacity/operational analysis. The consultant will require prior approval from MTO to use any software other than those listed above and may be requested to submit an electronic copy of the files. If the proposed development directly impacts freeway operations there may be a need to undertake microsimulation to assess these impacts. The ministry’s regional Corridor Control offices should be contacted if there are any questions as to these requirements.
A minimum of three copies of the TIS shall be submitted to MTO for review.
