2. North Williams Avenue:

Five segments

PoyourowConsultingStreet Segments

• Segments:1. Weidler – I-5 On-Ramp2. I-5 On-Ramp to Russell3. Russell to Cook4. Cook to Skidmore5. Skidmore to Killingsworth

Segment 1Weidler

to I-5 On-Ramp

PoyourowConsulting

Segment 1: Weidler to I‐5 On‐Ramp

N Williams Avenue (northbound), at Broadway

PoyourowConsultingSegment 1: Weidler to I-5 On-Ramp

• Characteristics:– Approximately 420 motor vehicles during peak hour

(Weidler to Broadway)– Approximately 240 bicyclists during peak hour

(Weidler to Broadway)– Three auto lanes– Population = 0– No bus stops

PoyourowConsultingSegment 1: Weidler to I-5 On-Ramp

• Issues:– Busy traffic environment– Serves important traffic delivery function to I-5– High number of heavy vehicles– Queues can back up from I-5 on-ramp

• Opportunities:– Motor vehicle traffic volumes may be low

enough that two travel lanes would be enough, without causing any congestion

Segment 2I-5 On-Ramp

to Russell

PoyourowConsulting

PoyourowConsultingSegment 2: I-5 On-Ramp to Russell

• Characteristics:– Approximately 700 motor vehicles during peak hour– Approximately 300 bicyclists during peak hour– 52% of vehicles exceed the speed limit, many

neighbor complaints– 3 bus stops (Lines 4 and 44)– Crosswalks at Tillamook and Page used by

vulnerable pedestrians (including school children, and adults with disabilities)

– Light to moderate parking demand– Total populations = 738– Kids under 18 = 97

PoyourowConsultingSegment 2: I-5 On-Ramp to Russell

• Issues Identified:– Motor vehicles speeding– Cyclists passing one another in the auto lane – Bike / bus passing stress– Poor crosswalk compliance

• Opportunities:– Motor vehicle traffic volumes are low enough that

one lane would likely work without congestion, even during p.m. peak hours

Segment 3Russell

to Cook

PoyourowConsulting

PoyourowConsultingSegment 3: Russell to Cook

• Characteristics:– Approximately 800 motor vehicles during peak hour– Approximately 400 bicyclists during peak hour– 4 bus stops, heavy use (Lines 4, 24 and 44)– Light to moderate parking demand, especially on

west side– Preventable crashes and poor visibility for turns onto

Williams– Total population = 816– Kids under 18 = 108

PoyourowConsultingSegment 3: Russell to Cook

• Issues:• Bike/bus passing• Cyclists passing one another in the auto lane• Very poor visibility for left turns onto Williams• Traffic from Fremont Bridge enters Williams at

• Opportunities:– Parking demand is relatively low on west side of

street

Segment 4Cook

to Skidmore

PoyourowConsulting

PoyourowConsultingSegment 4: Cook to Skidmore

• Characteristics:– Heaviest traffic section – approximately 950 to 1,100

motor vehicles during peak hour– Approximately 400 bicyclists during peak hour– Moderate to heavy parking demand– Busy crosswalks, especially at Failing– 5 bus stops (Line 44 only, except 24 at Fremont)– 31% of vehicles exceeding speed limit– Total population = 1,511– Kids under 18 = 257

PoyourowConsultingSegment 4: Cook to Skidmore

• Issues:– Crosswalk visibility and compliance– Visibility for vehicles, bikes, people crossing or turning

onto Williams– Hazards in bike lane (e.g. double-parked cars, delivery

vehicles, open car doors)– Some concern about speeding

• Opportunities:– Developing commercial district– Slowing vehicle speeds would reduce conflicts, stress, and

hazards

• Constraints:– Auto traffic is enough that two travel lanes are likely

needed during peak hour– Parking is heavily used on certain blocks

Segment 5Skidmore

to Killingsworth

PoyourowConsulting

Segment 5: Skidmore ‐

Killingsworth

N Williams Avenue (northbound), at Alberta

PoyourowConsulting

PoyourowConsultingSegment 5: Skidmore - Killingsworth

• Characteristics:– Approximately 700 to 850 motor vehicles during

peak hour– 3 bus stops (Line 44)– Moderate parking demand– Busy crosswalk/bike crossing at Going– More residential character– Total population = 1,572– Kids under 18 = 317

PoyourowConsultingSegment 5: Skidmore - Killingsworth

• Issues:– Neighbors concerned about auto speeds– Visibility for traffic turning or crossing at

Going– Intersection geometry and bus operations

are challenging at Alberta

• Opportunities:– Motor vehicle traffic volumes are low

enough that one lane would likely work without congestion, even during p.m. peak hours
