1 Some important pedestrian considerations 4-1

2 Skew increases crosswalk length, decreases visibility 4-2

3 Right angle decreases crosswalk length, increases visibility 4-3

4 Bend OR Skewed intersection reduces visibility Driver looks left, doesn’t see pedestrian on right 5-4

5 Adjust skew by bringing out curb Bend OR 4-5

6 Result: driver behavior change Bend OR 4-6

7 Large radii 1.Increase crossing distance and 2.Make crosswalk & ramp placement more difficult Curb radius: Small radii are safer for pedestrians 4-7

8 Effect of large radius on drivers They drive fast, Tigard OR ignoring pedestrians 4-8

9 Minimize curb radius 1. Calculate effective radius: Larger than built radius if travel lanes offset from curb with parking and/or bike lane 5-9

10 Canyonville OR Minimize curb radius Don’t choose larger design vehicle than necessary 3. Don’t choose larger design vehicle than necessary Bus makes turn several times an hour 4-10

11 Santa Barbara CA Moving van, once or twice a year; peds cross every day Minimize curb radius 3. Don’t choose larger design vehicle than necessary 4-11

12 Canyonville OR Minimize curb radius 5. Trucks can make very tight turns at slow speeds 4-12

13 Curb extensions Most focus is on reduced crossing distance Better visibility between peds and motorists Traffic calming Room for street furniture Other advantages: 4-13

14 Better visibility 4-14

15 Pedestrians wait where they can see, in front of parked cars Curb ext. places pedestrian where he can see and be seen 4-15

16 Before: high speed right-turns Salem OR Curb ext. slows right-turning vehicles 4-16

17 After: slow speed right-turns Curb extension and new corner radius must be designed together – see earlier radius discussion Salem OR 5-17

18 Curb ext. increases likelihood drivers will yield to peds Joseph OR 4-18

19 Curb extensions allow room for street furniture But use care not to block sight lines 5-19 Public art Bike parking Street trees Newspaper boxes

20 Curb Extension Integrated with the Sidewalk “Parking pockets” in furniture zone have similar surface materials as the sidewalk 4-20

21 Before: road looks and feels wide Lake Oswego OR 4-21

22 After: curb extension integral to sidewalk Street looks narrow even with no parked cars Lake Oswego OR 4-22

23 Pedestrian Islands Benefits: Separate conflicts & decision pointsSeparate conflicts & decision points Reduce crossing distanceReduce crossing distance Improve signal timingImprove signal timing Reduce crashesReduce crashes 4-23

24 Fresno CA Peds could start crossing here… … instead of here 4-24

25 Cut-through preferred over ramps Cut-through preferred over ramps Truncated domes at cut-throughs Truncated domes at cut-throughs 8’ or more preferred width – 6’ minimum 8’ or more preferred width – 6’ minimum Salem OR Island Design Details 5-25
