Traffic and Transportation Impact Studies (TIS) / Assessments (TIA)

New development sites can impact the surrounding roadway systems by adding additional traffic volume to existing traffic or altering existing traffic patterns. In addition to designing appropriate access for proposed developments, transportation engineers are normally required to maintain a satisfactory level of operation and traffic safety for the roadways users adjacent to the proposed developments. The road users are broadly defined as all surface transportation modes including automobiles, transit, trucks, pedestrians, bicycle and other non-motorized modes of transportation.

Traffic Impact Studies (TIS)/Traffic Impact Assessments (TIA) gather and analyze information that will help determine the needs for any improvements to interior, adjacent and exterior roadway systems within the vicinity of a proposed development. Oftentimes, a TIS/TIA is conducted within the context of a larger environmental impact study, which is typically mandated for projects planned under the auspices of a public jurisdiction. A TIS/TIA primarily serves two purposes: 1. To determine and disclose all significant traffic or transportation impacts of a proposed development; and 2. To identify mitigation measures that would likely to reduce or otherwise compensate for the negative traffic impacts. In many urban jurisdictions, traffic impacts and mitigations are routinely among the most visible and controversial aspect of environmental issues for development projects

Our team of professionals have considerable knowledge and experience in preparing traffic and transportation impact studies/assessments as well as conducting traffic operation evaluations and warrant analyses for various commercial, residential, office, educational, institutional and mixed-use land development projects of all sizes both in Canada and the US.
