Hourly trips refer to the number of trips expected to occur during the morning and evening peak hours.2. Hourly truck trip estimates assume truck trips occur equally across a 7-hour workday, and rounded up toethe nearest trip3. Hourly worker trip estimates assume one-third of daily workers arrive during the peak hour.Trip DistributionThe Project would generate two types of trips - construction worker trips and truck trips.This section describes the distribution pattern of each.Construction Worker Trip DistributionIt is expected that approximately 80 percent of site worker trips would generally accessthe site from SR 13, with 10 percent of trips from Moraga Avenue west and 10 percentfrom Park Boulevard west. Of the trips to/from SR 13, about one-third are expected fromthe north while the remaining two-thirds are expected from the south, as depicted onFigure 3.6-4. Worker trips from SR 13 to the north would access the Project site via theMoraga Avenue Interchange, and travel on Estates Drive to the Project site. Half of tripsfrom SR 13 to the south were also assumed to access the Project site via the MoragaAvenue Interchange, with the other half using the Park Boulevard interchange. Thoseusing the Park Boulevard interchange would travel on La Salle Avenue and Estates Driveto the Project site. Trips from Park Avenue, west of the study area, would probably filterthrough the neighborhood on Estates Drive from south of the site. While constructionworkers would be encouraged to remain on the main travel routes, some may deviate andtravel on minor residential streets, such as Dawes Street, as these streets provide a moredirect route to the site.sb09_001.doc 3-6.13 7/22/2009
