() 3) Figure 8 shows various turning radius tem- plates for intersections used by transit vehicles. These templates shall be used to guide curb radius decisions within these intersections. 4) The 25' turning radius standard is designed for making a safe right turn at ten miles per hour or less. Higher speed turns would require a larger turning radius. The design radius may also be inadequate due to insufficient lane width, the type of movements by other vehicles or pedestrians, or the presence of obstructions, such as signs. To be certain of meeting bus turning requirements, it is useful to test a simulated version of a proposed street or driveway design. The City of Eugene shall coordinate with LTD on intersection design to ensure that adequate turning radii are provided to accommodate bus movements. Intersection Design for Transit Turns · Designers should plan for an effective radius of 28' (right rear wheel) · Transit vehicles are assumed to be 41' by 8'6" · Assumes no encroachment into opposite lanes · Assumes parking is prohibited within 20' of end of curb return · These are examples, appropriate curb radii must be determined on a case by case basis by Eugene Public Works Transportation and lane Transit District Case 1 · Turn into one lane · No parking or bicycle lanes 112' 110' Case 3 · Turning from one 10 foot lane to another 10 foot lane · No parking or bicycle lanes Figure 8 Case 2 · Turn into one lane · Parking lane before and after turn tr /12' /12' ~51 fr Case 4 · Turn into one lane · Bicycle and parking lanes before and after turn 11
