may be accomplished using experience, judgment, and knowledge of local conditions. 8. include: Transportation Systems and Level of Service Requirements. The TIA shall 8.1 Roadway and Intersection Capacity. 8.1.1 All streets and intersections contiguous to the development; 8.1.2 All streets and intersections that provide direct access to or from the development, regardless of the generated volume of traffic; 8.1.3 All streets and intersections off site from the development that will receive 50 or more additional peak-hour vehicular trips upon completion of any phase of the development; 8.1.4 Level of Service standards for the completed development as calculated by methods identified in the most current edition of the Transportation Research Board's Highway Capacity Manual or Highway Capacity Software. Other capacity analysis programs may be used if approved by the City Traffic Engineer, or designee. All intersections and/or street segment links within the study area must be evaluated for capacity. The manual and software contain separate calculations for two-lane and multi-lane free-flow roadways, signalized arterials, and signalized and unsignalized intersections. 8.2 Roadway and Intersection Safety. Projected accident rates for off-site streets and intersections that will receive 50 or more additional peak hour trips upon completion of the development, taking into consideration proposed mitigation measures including access restrictions. Accident records must be researched for all critical segment links and intersections within the study area. If accident rates, or patterns of accidents, are forming at certain locations, a determination must be made on whether the probability of these occurrences will increase with the addition of the projected traffic volumes. Examples of recurring accidents include numerous right-angle or rear-end collisions at an intersection, or a high frequency of vehicles leaving the roadway on a horizontal curve. 9. Meeting Minimum Level of Service and Safety Standards. The traffic study shall identify mitigation measures to meet a minimum level of service and safety standards. The TIA shall state whether the applicant will have the mitigation measures in place at the time of occupancy of the properties, or if a financial commitment is in place to complete the necessary infrastructure within a reasonable length of time from the approval date of the development. 10. On-Site Plannin~ and Parkin~ Principles. 10.1 The TIA shall show: 10.1.1 How off-site roadway improvements are integrated with on-site circulation patterns; 10.1.2 Driveway traffic volumes, both in terms of queuing space and Administrative Order - 6 r:\adminord\rules\02stdstia2ao. wpd(06/19/02)
