A proposed land development, redevelopment or rezoning project requires Traffic Impact Studies to evaluate whether transportation infrastructure can support additional trips a project will generate. For developers and municipal stakeholders, Traffic Impact Studies provide critical information about land use and planning decisions. Below, we discuss the importance of Traffic Impact Studies and how partnering with an experienced team of engineers and environmental consultants can help with building or improving transportation infrastructure.
A land development plan that generates traffic, such as a shopping mall, will have many stakeholders. Residents are curious how construction and the proposed development will affect their daily lives. Developers must understand required mitigation measures or improvements, along with cost implications. The municipality must answer the public's questions regarding the project's environmental impact, prepare related environmental studies and ultimately decide whether to approve the project. Finally, public works and state transportation agencies need site-specific information to design the facilities and approve access. Traffic Impact Studies provide important information to help all stakeholders understand and evaluate the project.
Traffic Impact Studies vary in detail and complexity depending on the type, size and location of a development project. Nonetheless, the objective of every Traffic Impact Study is the same. Traffic Impact Studies review:
Traffic Impact Studies not only evaluate the effects of a particular set of developments but also provide information on broader development plans and decisions that affect overall community growth patterns and characteristics. Key reasons to conduct Traffic Impact Studies include:
Site development and review processes are governed by guidelines, policies and ordinances established by local governments. In most cases, the primary requirement to perform a Traffic Impact Study is based on the number of trips generated by the site, the type and size of the development and other site characteristics. A common baseline requires a Traffic Impact Study when a proposed land development generates 100 trips to the adjacent street network during the peak traffic hour.
Not all projects require a detailed Traffic Impact Study. Based on the type and size of the development, a Traffic Impact Study can vary from a cursory review and a letter of opinion from a qualified professional to a comprehensive analysis and report that includes details about the area-wide transportation system and other planned or approved developments in the vicinity.
In some cases, the local government performs the Traffic Impact Study. However, this is not a common practice, so municipalities and developers often need to find qualified transportation professionals to conduct a Traffic Impact Study. The transportation operations and design work also requires a qualified and experienced professional engineer's supervision.
