The study area shall include all pertinent intersections and streets impacted by development traffic. The sections shall at a minimum incorporate the information identified below.Ī. Provide a statement of the scope of the analysis and identify the limits of the study area. The TIA shall at a minimum include the following sections: Introduction, Existing Conditions, Development Traffic, Future Traffic, Traffic Operations, and Mitigation. The TIA shall be prepared by an engineer licensed to practice in the State of Washington with special training and experience in traffic engineering.ĭ. Submittal Requirements. This would include site-generated traffic for all turning movements for the peak hours at all affected intersections.Ģ. The development lies within an area that contains an existing or proposed local improvement district (LID), local/State transportation improvement areas programmed for development reimbursements or at locations that have latecomer agreements.ģ. If a TIA exists but is more than two years old, the Director may require a new or revised TIA prior to permit issuance.Ĭ. Qualifications for Preparing TIA. A TIA will be required if any of the following conditions are met:ġ. The development generates 20 or more trips in either the a.m. To adequately assess a development’s traffic impact on the transportation system and level of service (LOS), the Director may require a TIA based upon the evaluation of the size of the development proposed, existing street and intersection conditions, traffic volumes, accident history, community concerns, and other pertinent factors relating to traffic impacts attributable to the development. The Director may accept the TIA as satisfying the requirements for a concurrency test as identified in UPMC Title 22.ī. When Required.

A TIA shall be a thorough review of the immediate and long-range traffic impacts. The level of detail and scope of work of a TIA may vary with the size, complexity, and location of the development. The purpose of the TIA is to determine the impacts of the development traffic on the existing and proposed street network and the impacts of the existing and projected traffic on the development.

It is specifically concerned with the generation and distribution of traffic to and from the development. The TIA is an integral part of the development impact review process. A traffic impact analysis (TIA) is a specialized study of the impacts that a certain type and size of development will have on the surrounding transportation system. 13.20.130 Standardized format for traffic analyses.Ī. Introduction. These standards and guidelines apply to neighborhood collector streets and local streets associated with new development as well as qualifying modifications to existing development. The “City of University Place Design Standards and Guidelines for Streetscape Elements” are contained in Article IX, Design Standards and Guidelines for Streetscape Elements. The purpose of this chapter is to provide for the development of an integrated, uniform, multimodal, fully accessible transportation system that facilitates present and future travel demand with minimal environmental impact to the community.Ī. The design objective for vehicular zones is to create a circulation system that provides for the safe and efficient movement of vehicles and reduces conflict with pedestrians and bicyclists and to provide roadway standards that will help create streets that are inviting, multimodal public places.ī. The design objective for pedestrian zones is to provide a high level of design detail, promote walkability by improving pedestrian safety, convenience, and comfort, and enhance the aesthetic character and quality of the pedestrian experience.
