Oops -- NO, the blue arrow is NOT where the near-lane-parallel traffic would be waiting!
It is in the lane furthest from the pedestrian -- look at the illustration to the right, and you can see that after they surge forward, the vehicles pass the pedestrian in the far lane.
Ooooh, no -- you fell for the oldest trick in the book! the blue arrow is NOT where the near-lane-parallel traffic would be waiting - it is in the FAR lane, and if you look to the right you'll see that those vehicles stay in the far lane.- Bourquin, E., Wall Emerson, R., Sauerburger, D., & Barlow, J.

Congratulations, you are correct! The blue arrow is where the near-lane-parallel traffic would be for this pedestrian.

Oops -- the answer should be YES, the blue arrow is where the near-lane-parallel traffic would be waiting. Take a look at the example where the parallel street is on your left -- the near-lane-parallel traffic (that is, the traffic in the lane nearest to your crosswalk) is close beside you.

Oops -- the answer should be YES, the blue arrow is where the near-lane-parallel traffic would be waiting. Take a look at the example where the parallel street is on your right -- the near-lane-parallel traffic (that is, the traffic in the lane nearest to your crosswalk) is ahead of you, on the other side of the parallel street.

The only potential conflict is with vehicles turning left.
However, vehicles can usually turn left without any conflict when there are only left-turning vehicles coming from the opposite direction.
Return to Signalized traffic patterns for vehicles
Left-turning vehicles wait for a gap in the opposing traffic before turning.

Figure 2. Scatterplot of the percentage yielding by speed for the cane-using and noncane-using conditions.
Description: The figure is a scatterplot. The x-axis is labeled Vehicle approach speed (mph) and has 4 values, from left to right: 20, 30, 40, and 50. The y-axis is labeled Percentage of vehicles yielding and has 11 values, from bottom to top: 0, 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100. Black dots plotted in the graph represent Noncane; White diamonds represent Cane. A horizontal line drawn in the upper half of the graph reads: Cane R(squared) = 0.333. A horizontal line drawn in the center of the graph reads: Noncane R(squared) = 0.038. All values in this narrative are approximations.
-
20-30 mph: Noncane: 11 ranging from 0-100; Cane: 8 ranging from 80-100.
30-40 mph: Noncane: 11 ranging from 30-70; Cane: 10 ranging from 50-100.
40-50 mph: Noncane: 8 ranging from 0-100; Cane: 2 ranging from 50-80.
