District 6 Town Hall September 23, 2014 SOUTH ORANGE GROVE BOULEVARD ISSUES AND OPTIONS Issues Department of Transportation
Concerns Constraints/Opportunities • Speed of traffic is too • Historic nature of the high roadway • Difficult for people to > Role of Orange Grove in cross safely the Rose Parade • Difficult to turn left to or • Unsuccessful prior from cross streets and attempts to reduce driveways number of traffic lanes > Lack of left turn lanes > Deemphasized designation • Hostile roadway environ- • Shared jurisdiction at ment for bicyclists Columbia with South Pasadena
5 What’s Happening
Department of Transportation • Review of current conditions > Crash Data Analysis > Speed Information > Traffic Signal Operation . Discussions underway with the City of South Pasadena to use “split” phasing for the north-south approaches at Columbia Street . Similar to the operation at California Boulevard • Bicycle Transportation Plan > Investigation of protected bicycle lanes

Current Conditions
Department of Transportation
• 48 foot roadway in 96 foot Right of Way > Off-Peak Parking allowed; but parking usage is low . Street operates as four lanes for most of the day • Most intersections are not signalized > Creates hostile conditions for walkers and bicyclists

Volumes
Department of Transportation • Peak Hourly Volume 1,300 vehicles per hour • Average Daily Traffic: 19,000 to 26,000 vpd
8 Speeds
Department of Transportation • Posted Speed Limit is 35 mph • Measured speeds: > 85th percentile - 42 mph . Speed at which 85% of the traffic is traveling at or under (criteria to set speed limits per CA statute) > 50th percentile - 36 mph . Average Speed or Speed at which half the traffic is traveling at or under • More than half of the traffic is exceeding the posted limit
9 What Does It All Mean?
Department of Transportation • Four Lanes + Moderate Traffic = High Speeds • + No left turn lanes = Difficulty in Turning > Turning motorists use inappropriate gaps in traffic and don’t consider limited sight distance of approaching vehicles in outside lanes > Turning motorists are not watching for people on the sidewalk or in the crosswalks • + No Bike Lanes = Hostile Cycling Conditions > Result is few bicyclists using South Orange Grove > High car:bike speed differential increases crash severity 10
