Council District 5 Community Outreach Meeting

Background

 Requests to review traffic safety and traffic calming within the Dow-

Johnston neighborhood area.

 Manhattan Beach Blvd, Robinson Street, Vail Avenue and Inglewood

Avenue.

 Speeding, turn movement prohibitions, pedestrian and bicycle safety,

traffic signal operations etc.

Data Collection

 Field surveys  Traffic volume counts  Speed survey data  Accident history survey

Traffic Calming Tools

 Can slow vehicular travel speeds  Can reduce the frequency and severity of traffic collisions  Can increase safety for pedestrians  Traffic Calming is not “one size fits all”  Typical problems Traffic Calming Tools help solve:

 Excessive vehicle speeds  Vehicle and pedestrian safety

Class II & Class III Bike Facilities

 Class II Bike Lanes – striping and signage to denote separated bike

lanes on roadway

 Class III Bike Route – pavement marking and signage to denote

bicycle route with shared bike facility markings, “sharrows”

 Benefits – potential to enhance bicyclists safety - driver awareness of

bicyclists on roadway; bike lanes narrow travel lane; livability and bicycle facility-type enhancements

 Disadvantages – generally minimal, additional striping considerations

High Visibility Crosswalks

 Ladder or stair type crosswalks

 Benefits - Enhance pedestrian safety by increasing motorist awareness of

the potential for encountering crossing pedestrians

 Disadvantages – More costly than standard crosswalk

Curb Bulbouts

 Roadway extensions

 Benefits - Reduce vehicle speeds along the roadway; reduces pedestrian

crossing area and roadway exposure

 Disadvantages – Generally costly (dependent on materials)

Curb Extensions / Bulb-outs

Speed Limit Signage

 Residential prima facie speed limit  Speed limit signs (oversized)  “25” pavement markers  Rotational radar feedback signs

Benefits

 Remind and reinforce driver of roadway speed limit

Traffic Circles / Modified T’s

 Raised medians located in intersections, constructed to reduce vehicle

speeds.

Council District 5 Community Outreach Meeting

 Benefits – speed reduction,

accident severity reduction, consistent driver behavior.

 Disadvantages – construction

costs, potential for loss of parking.

Median Center Island

 Raised islands in the center of the street to physically narrow roadway  Benefits – Narrow roadway helps control speeds  Disadvantages – Costs, typically removal of on-street parking and/or

modifies driveway accesses

LEGEND: Existing speed limit sign to remain unchanged Replace speed limit sign with

Install new speed limit sign Install new oversized speed limit sign Existing “25” pavement marking to remain unchanged Install “25” pavement marking (indicates direction of travel) Place radar speed feedback signs on a rotational basis 25

DOW AVE – JOHNSTON AVE Long-Term Safety Enhancement and Traffic Calming Recommendations

LEGEND: Modify the signal to provide protected left-turn phasing and adjust timing Replace existing all-way stop with traffic circle Install modified T-intersection Install landscaped center islands

10’ LANE Maintaining south curb line results in encroachment into #1 WB thru lane Relocating turn lane to eliminate encroachment into #1 WB thru lane requires reconstruction of south curb line (+/- 3 ft)

BELAND BLVD AT JOHNSTON AVE Traffic Movement Counts 5/15/19 – 7:00-9:00 AM

Notes: 1. 20 total prohibited movements between 7-9 AM. 2. 5 right-turn prohibited movements do not appear to be commuters. 3. 4.2% of WB volume is a prohibited movement. 4. All left-turn prohibited movements appear to be commuters. 5. 5.2% of EB volume is a prohibited movement.
