Site Description Evaluation of Data
◦ Pedestrians◦ Bicyclists◦ Motor Vehicles
Observed Trends Site Comparison Issues/Proposed Solutions
Outline
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
Site Description
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
Site Description
Site Description
Pedestrians and cyclists traveled from 4 to 3 and 3 to 4
Motor vehicles traveled from B to D and D to B
Crosswalk Data Collection Layout
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

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
Bicycle Evaluation
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

6.75 minutes of delay during observation hour
Bicycle Evaluation
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
Motor Vehicle Evaluation
Motor Vehicle Evaluation
Violation Counts for Vehicles
A= Abrupt stop, B= No stop, C= Impedes on crosswalk
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
Observed Trends
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

◦ Signal placement◦ Flashing signal length
Crosswalk Issues
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
On-Street Parking
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
Overhead Flashing Sign
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)
Overhead Flashing Sign
Overhead Flashing Sign
Solution 3: HAWK signal for each direction of traffic (shown below)
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.
