5. Pass-by Reasonableness Checks The number of pass-by trips should not exceed 10 percent of the adjacent street traffic during peak hour Strong justification must be provided to document pass-by rates greater than 25 percent of the total external trip generation for the developments retail portions –Ensure proposed development displays ideal characteristics to generate pass-by trips

6. 10% of Adjacent Street Traffic Represents maximum number of trip ends that can be subtracted from base trip generation for pass-by analysis. Common misuse: –Adjacent street traffic = 1000 –10% = 100 –Those 100 vehicles enter the project, then exit the project for a total reduction of 200 from the trip generation

7. Driveway Traffic Will Include All Of The Pass By Traffic 1000 1,000 Beware when analyzing driveways: analysis must include pass- by trips in driveway volumes.
