In general, however, the potential for collisions increases as traffic volumes increase. While the frequency of collisions in the study area can be expected to increase in the future, without the project and more so with the project, quantifying the magnitude of increase is not practical. Nonetheless, based on the total traffic volumes and existing collision frequency (0.66 collisions per year) that is substantially below a level of concern, traffic safety is not expected to be a substantial problem in the future with or without the project. 17 Would pedestrian, bicycle, and other off-road use and facilities be affected? There are no planned non-motorized improvement projects identified within the study area that would be affected by the project alternatives. Therefore, without or with the project, the future non-motorized system within the study area is expected to be similar to the existing conditions. With the substantial increases in traffic volumes, roadways previously shared by motorized and non- motorized travel modes could pose safety concerns. Although the amount of non-motorized activity in the study area is relatively low, the demand from this development and others may increase non-motorized demand in the future. This may be especially pronounced in Alternative 2 with a multi-family component. To accommodate pedestrians and children on bicycles, sidewalks and signage may become desirable to reduce the potential for vehicle-to-pedestrian collisions. State law (RCW 58.17.110) requires that subdivisions provide safe public walkways for school children from residences to schools or to bus stops. Traffic hazards are especially a concern for winter snowmobile use when plowed road areas are narrow and both vehicle and snowmobiles may be operating at speeds that do not allow adequate stopping distance or effective avoidance in cases of imminent collision.
