Site Description Evaluation of Data ◦ Pedestrians ◦ Bicyclists ◦ Motor Vehicles Observed Trends Site Comparison Issues/Proposed Solutions
3
Intersection: 2 travel lanes, a bike lane, and a bus stop, on each side of the 10 foot wide median Total crosswalk length= 70 feet w/continental markings Crossing occurs mid-block w/signalized intersection approximately 300’ to the East and West. Motor vehicle speed 35 MPH both directions
4
2 “Stop Here for Pedestrian” signs and 2 “Pedestrian and Bicycle Crossing” signs as warning Wide sidewalks for pedestrians from MAX, I-205 multi-use path, and bus stops Adequate lighting/signage
6
Pedestrians and cyclists traveled from 4 to 3 and 3 to 4 Motor vehicles traveled from B to D and D to B
7
Pedestrians crossed from 3 to 4 and from 4 to 3 Violations ◦ Did not push button before crossing ◦ IPod or other listening device During observation period, no pedestrians were seen using cell phones while crossing On-street parking and buses prevent driver from seeing the pedestrians at crosswalk
8
Total Pedestrian Counts Violation Counts for Not Using Button From 3 to 4From 4 to 3 0-15 (min)149 15-30 (min)54 30-45 (min)20 45-60 (min)74 Total2817 From 3 to 4From 4 to 3 0-15 (min)29 15-30 (min)00 30-45 (min)20 45-60 (min)11 Total510 Five pedestrians from 3 to 4 and three pedestrians from 4 to 3 were seen using a listening device
9
Violation Data 15/45 = 33.33% did not use signal 8/45 = 17.78% using an iPod or similar device 23/45 = 51.11% total undertook a violation 6.33 seconds delay per approach pedestrian= LOS A 4.8 minutes delay during observation hour
10
Bicycle crossed from 3 to 4 and from 4 to 3 Violations ◦ Did not push button before crossing= T on chart ◦ Were not wearing a helmet= H on chart During observation period, no cyclists were seen riding on sidewalk or using wrong side of road On-street parking and buses prevent driver from seeing the cyclists at crosswalk
11
Total Bicycle Counts Violation Counts for Bicycles *One cyclist rode from B to D w/o wearing a helmet From 3 to 4From 4 to 3 0-15 (min)46 15-30 (min)48 30-45 (min)33 45-60 (min)42 Total1519 From 3 to 4From 4 to 3 0-15 (min)T31 H00 15-30 (min)T61 H01 30-45 (min)T04 H00 45-60 (min)T32 H01 Total 1210 T= Did not push button, H= No helmet
12
Violation Data 20/35 = 57.14% did not use signal 3/35 = 8.57% did not wear a helmet 23/35 = 65.71% total undertook a violation 11.9 seconds delay per approach bicycle= LOS B 6.75 minutes of delay during observation hour
13
Vehicles crossed from B to D and from D to B Violations ◦ Vehicle stops abruptly= A on chart ◦ Vehicle does not stop for pedestrian= B on chart ◦ Vehicle impedes on crosswalk= C on chart Many drivers did not stop for pedestrian at crosswalk even when signal was flashing Oregon law states drivers must stop and remained stopped for pedestrians until they have cleared your lane and adjacent lane Law was violated numerous times
14
Violation Counts for Vehicles A= Abrupt stop, B= No stop, C= Impedes on crosswalk
15
Pedestrians utilizing crosswalk tended to feel safer when a bus was making stop Speeding motor vehicles not a concern b/c of controlled adjacent signalized intersections Traffic “backing up” from intersection led to blind-spots and decreased crosswalk visibility Majority of pedestrians/ cyclists used signal and were cautious throughout
16
NE Martin Luther King Jr. Boulevard and Going Street examined Unsignalized intersection Configuration of this crosswalk was similar to SE Division and Green Line Vehicles extremely respondent Trend attributed to driver expectation at crosswalk Drivers expected to yield for pedestrians/ bicyclists
18
On-street parking Overhead flashing pedestrian sign ◦ Signal placement ◦ Flashing signal length
19
Issue: Parked cars on south side of Division preventing drivers from seeing the pedestrians/cyclists Solution: Remove some on-street parking stalls close to the crosswalk
20
Issue 1 Signal placed above median which is not in the driver’s line of sight Many drivers do not slow down when signal is flashing Daily drivers familiar with flashing when no pedestrians present which leads to behavioral habits such as not slowing down Drivers did not see signal b/c more concentrated on intersection ahead
21
Solution 1: Place separate signals above westbound and eastbound lanes Placement will be in line of sight of the drivers Solution 2: Remove signal and place in- pavement lighting (shown at right)
22
Solution 3: HAWK signal for each direction of traffic (shown below)
23
Issue 2: Signal flashes for two minutes after button is pressed Solution: Change signal time to 30 seconds MUTCD- design for 3.5 feet per second which would mean 20 seconds of signal flash for the 70 foot crosswalk.
