Mr. Tim Nelson -4- Apr i 1 30, 1987 TRAFFIC FORECASTS The traffic forecasting and analysis efforts Focus on the p.m. peak hour (about 4:30 to 5:30-p.m.) because traffic volumes typically are at their highest level of the day during that hour. The first step in the traFfic forecasting process is to predict the number of trips generated by the proposed development. Utilizing data publ ished by the Institute of Transportation Engineers1, the projected p.m. peak hour trip generation is as follows: P.M. Peak Hour Trip P.M. Peak Hour Generation Rates Trips Bu i I ding ill Out Total ill Out Total 105,750 Sq. ft. office 0.41 1.62 2.03 43 171 214 54,200 Sq. ft. oFfice 0.4 2.42 2.82 22 Ul. 153 Totals 65 302 367 Given the limited trip generation by the existing uses (eight homes and the vault company) that would be replaced by the proposed development, the trip generation results From the preceding table have been added completely to the existing traFFic on Haml ine Ave. The next step involved predicting the directional distribu- tion of trips to and From the development. To accurately accompl ish this purpose, a survey was perFormed of the directional distribution of trips leaving the Rosevil Ie Professional Center, an office development across Hamline Ave. from the subject site. This survey was conducted from 4:00 to 5:30 p.m. on April 27, 1987, and involved recording the route and direction of travel for all vehicles leaving that development. Based on these.survey results, it is estimated that trips generated by the Everest OfFice Plaza development wil 1 distribute as foflows: "Trip Generation," Institute of TransportatIon Engineers, 1982.
