Adelaide Landing Residential Development Traffic Impact Analysis 1/31/2017 TH 61 & 134th Street North Likewise, the westbound approach recorded LOS-E/F in the p.m. peak hour, most likely due to minimal adequate gaps in TH 61 traffic to complete the turn. "Cut -Through" Traffic Based on relative distance of residential pockets to access points, Westwood used engineering judgment to estimate the effect of "cut -through" traffic. Due to the curvilinear design of the development, the likelihood of traffic "cutting through" Adelaide Landing to either TH 61, 140th Street North or 130th Street North has been diminished. Because the tendency of drivers to "cut -through" a neighborhood is based on perceived travel time savings, the curvilinear design of the neighborhood streets in the development slows driver speed and thus hinders perceived mobility. Drivers are more likely to maintain their existing travel patterns rather than "cut through" the Adelaide Landing neighborhood. Most drivers will likely seek the path of least resistance to get to get to their destinations. Therefore, if drivers can travel at higher speeds and more directly, they will use the adjacent arterial network to get to their destinations. If, however, the arterials (especially TH 61) are overwhelmed with peak hour traffic under current geometric conditions, drivers will seek alternate routes for through traffic. Therefore, the neighborhood arterial within Adelaide Landing may see "cut through" traffic. This condition will become more acute between the near -term development scenario of 2022 and the long-term scenario of 2040, as additional background traffic growth occurs along the TH 61 corridor. The condition will not abate until additional capacity is created along TH 61. Westwood does not recommend unrealistically low speed limits along neighborhood streets or unwarranted multi -way stop control at intersections in efforts to abate "cut through" traffic or excessive speeding. Some jurisdictions have installed "speed humps", or low and wide speed bumps, to slow traffic or to discourage "cut through" traffic. Nevertheless, to model the effect of cut -through traffic, Westwood and the City traffic engineering consultant agreed that an additional 10-15 trips per peak hour would be assumed to travel between the subdivision to the east of Adelaide Landing and 1301h Street in order to and from TH 61. These additional trips were distributed in each of the Build scenarios. Connections through Existing Neighborhoods Three development streets will intersect with 130th Street. Two of the connections at 130th Street will intersect with existing streets to the south — at Flay Road, and at 127th Drive. Other 37 Westwood
