4.4.1 Street system characteristics in the study area, including number of lanes, lane and shoulder widths, access control, and traffic control devices. 4.4.2 A description of roadway geometrics, including horizontal and vertical curvature. 4.4.3 Roadway functional classifications. 4.4.4 Posted speed limits and/or free-flow speeds. 4.4.5 Traffic signal locations, phasing, coordination and timing. 4.4.6 Congested locations within the study area as identified by the City or previous traffic studies at the time of application. 4.4.7 Accident history for 3 years prior to the application on major roadway links and intersections within the study area. 4.4.8 Transit stops, service, and usage. 4.4.9 Pedestrian and bicycle linkages. 4.4.1 0 Available curb and off-site parking facilities. 5. Peak Traffic Hours. The TIA shall include peak hour traffic counts for all streets within the study area at the time of application. Existing traffic counts (less than 2 years old) may be factored by an average 2% per year growth rate to establish the forecasted background traffic volumes. Growth rates less than this amount may be used for those roadways that are already approaching their theoretical capacity during peak periods if the lower growth rates are justified by a different methodology presented by a professional traffic engineer. Traffic counts shall be provided for: 5.1 The weekday a.m. peak-traffic period (a one-hour peak in morning traffic volumes occurring between 7:00 a.m. and 9:00 a.m.). 5.2 The weekday p.m. peak-traffic period (a one-hour peak in afternoon traffic volumes occurring between 4:00 p.m. and 6:00 p.m.). 5.3 The weekday midday peak-traffic period (a one-hour peak in traffic volumes between 11 :30 a.m. and 12:30 p.m.). 5.4 The peak-traffic period on Saturday (a one-hour peak in traffic volumes between 1 :30 p.m. and 2:30 p.m.). 6. Estimation of Trips Generated. The TIA shall include an estimate of the trips the proposal will generate. Proj ect trip generation rates shall be estimated using the most current version of the Institute of Transportation Engineers' Trip Generation Manual. Where available, equations may be used rather than average trip generation rates, but only if there are at least 20 data points in the sample and the Coefficient of Determination (R2) for the sample is greater than 0.75. 7. Site Traffic Distribution and Assienment. The TIA shall include manual traffic distribution and assignment based on the gravity model principle.
