Travel time for local industrial trips with a destination east of Bailey Hill Road increased about one minute, 32 seconds per vehicle. Based on the pre-closure _ traffic counts and the Origin and Destination Study, it is estimated that there were 1001oca1 industrial trips with a destination east of Bailey Hili Road, resulting in 2.56 additional vehicle-hours of travel time for local industrial trips per weekday. To summarize, the closure affects about 320 motorists per day, adding some 4.5 hours of travel time to their trips, or about 50 seconds per trip. Based on the small amount of added travel time, and the lack of negative feedback, this increase in travel time has not been a problem for motorists who used to use Stewart Road and is thus not a significant factor in the closure. • Intersection capacity: The closure will have minor effects on the capacity of four intersections: Stewart Road & Bertelsen Road, Stewart Road & Bailey Hill Road, l lth Avenue & Bertelsen Road and l lth Avenue & Bailey Hill Road. Based on an April 14, 1.998 traffic study, an estimated 540 vehicles used Stewart Road as a through street on a typical weekday. Most of the diverted through traffic will use W 11 `'' Avenue. The additional traffic, about about 270 vehicles in each direction, has little effect on the Level of Service (LOS) of either 1 lth Avenue intersection. LOS and peak hour delay per vehicle was estimated for both intersections using a computer program that models traffic flow at signalized intersections. The LOS remained the same at both intersections. At 11th & Bailey Hill, delay per vehicle increased by 0.5 seconds per vehicle, while there was a 3.4 second increase in delay per vehicle at l lth & Bertelsen. Thus, the additional 270 vehicles will have a slight negative impact on the intersections of l lth & Bailey Hill and 11th & Bertelsen. However, each intersection will still operate with an acceptable Level of Service. In summary, the affected intersections have sufficient capacity to handle the vehicles diverted by the closure of Stewart Road. Capacity at the Stewart Road intersections at Bailey Hill Road and Bertelsen Road was not a problem before the closure. The closure will result in only local traffic using those intersections and will slow the deterioration of Stewart Road. • Safety: (Note: this discussion of safety relates to the direct safety aspects of installing the barricade. For discussion of the broader public safety and welfare concerns, see, criterion (k) below.) All potential safety impacts, both positive and negative, are minor.
