Appendix F – Guidelines for Traffic Impact StudiesSection F.7 Additional Requirementsc. The appropriateness of access locations and the need for future trafficsignalsd. The need for auxiliary lanes (turn lanes, deceleration and acceleration lanes),including explanations of how acceleration/deceleration lengths, storagelengths, and taper lengths were determinede. Sight distances11. If the County has determined that the proposed development includes or affectshigh hazard locations, provide traffic accident data for all roadways in the studyarea. The accident data shall cover a minimum period of two years prior to theproposed study time. Accident data summaries for county roads may be obtainedfrom the County Engineering Department.12. Provide a summary of conclusions and recommendations from the Full TrafficImpact Study, including at least the following items:a. A summary listing of traffic impacts from the proposed development onexisting and proposed roads, intersections, and traffic signals in the trafficimpact area.b. A summary listing of improvements needed to assure adequate service andsafety levels on the roadway system affected by the proposed development.Identify and describe each proposed improvement, how and when it will befunded, and expected completion dates.F.7 ADDITIONAL REQUIREMENTSIn addition to the above requirements, the following shall be provided upon the request of theEngineer:A. Roadway Surface and Structural Integrity Analysis. Provide the following:1. Analyze the existing structural integrity of all roads in the traffic impact areasignificantly impacted by the proposed development. The Engineer may requireanalysis of affected roadways outside the traffic impact area.2. Identify impacts from additional site generated traffic on the existing surface.Identify improvements needed to maintain surface and structural integrity atacceptable County standards.3. The Engineer may require pavement cores if historic composite thicknesses arenot available.B. Structural Analysis of Bridges. Provide the following analysis for structurally deficientor functionally obsolete bridges impacted by the proposed development.1. Analyze current conditions of any structurally deficient or functionally obsoletebridges.2. Evaluate impacts of added site generated traffic upon such bridges.3. Identify structural or operational improvements needed to maintain the safeoperation of such bridges satisfactory to the Engineer.Larimer County Rural Area Road Standards Page F-8October 22, 2007
