Home My WebLink AboutStudy Session #1 - Supplemental Communication - Public Works • . Traffic Congestion . Management L_ I MAJOR TRAFFIC ENGINEERING FUNCTIONS • Safety ' Vehicle accidents • Bicycle and pedestrian facilities ' Roadway markings and signs • Vehicle speeds/enforcement ' Speed limits ' Regulatory posting ■ Long range planning ' Predicting future traffic demand ' Identifying capacity needs ' Changes in technology ' Street/signal system management and operation ' Signal operations and corridor coordination ' Markings&signs • Neighborhood traffic and parking issues 2 COMMUNICATION Mwt,g D: ®r g d: ..o • • What is the mission of Traffic Engineering? 3 Provide street system operations that balance the public's need for safety, mobility and convenience for the variety of users (modes) of the system 4 What is "balance" on our street system? ■ Very subjective and no technical definition ■ Most street design elements"dictated"by design standards • Many design standards include appropriate conditions for use ■ Need to establish clear priorities-important considerations are often at odds with each other(e.g. safety vs convenience) • Considers a variety of conditions that occur throughout the 24 hrs of the day—but"worst case"often prevails "Design person"often dictates design over the majority of users • Managing liability exposure is a significant factor 5. WHAT CURRENTLY GUIDES EFFORTS • General Plan Circulation Element ' ■ Traffic Signal Master Plan • Bike Master Plan • Staff reviews/traffic safety evaluations ■ Feedback from City Council/City Management • Residents ■ Funding opportunities/priorities ■ Measure M grants • Traffic safety grants • AQMD funding ■ City funds(General Fund, Gas Tax, Prop 42, etc.) s . . WHAT DO WE HEAR MOST FROM THE COMMUNITY? (in no particular order) • Safety • Speeding • Vehicle/motorcycle and truck noise • Congested corridors • Isolated intersection congestion • Unnecessary delays at intersection/waiting • Motorists not yielding to pedestrians One study can't effectively address all of these topics CONGESTED CORRIDORS • Beach Boulevard (mostly north of Ellis) • Edinger — Goldenwest to Beach • Pacific Coast Highway — Beach to Goldenwest • Commute times • Weekend and summer conditions Active with different modes(pedestrians,cyclists.. cars) • Pacific Coast Highway — Warner & Goldenwest High tide and weather event detours • Warner— Goldenwest to Newland • Adams — east of Bushard 9 ISOLATED INTERSECTION CONGESTION Common locations identified: • Beach/Edinger • Beach/Main/Ellis • Beach/Warner • Beach/Talbert ■ Brookhurst/Adams ■ PCH/Warner • PCH/Main • Warner/Magnolia ,a 9/13/2019 8ea�n sia .rarro Co LT" ct< I ao ocn Esi � � .�.,. ...., n a. .+ U s n �4 Ma•n�e .x 8xex. if Ch— Y 111 unt gton ++vain � t &arpe � v en Grove O'..w C Y i TEA ., rs , So I f ►► Wdl .l I S UTM C 85T f� A.u3CAA C wft 6 9/13/2019 ,It enY �I Cc K.4 T M. - �!

STRIKING THE RIGHT BALANCE >Safety Can Result In > Delays/Inefficiency Some safety treatments require Safety measures can result in less greater controls—eliminate motorist efficient vehicle and pedestrian judgement in certain situations movement • New traffic signals • Protected left turn arrows • Exclusive pedestrian phases • Split phase operations is STRIKING THE RIGHT BALANCE >Signal coordination can result in >Delays Signal coordination improves Increased delays to cross street efficiency along a given corridor traffic—common cycle length • Reduces travel time along corridor >Speeds • Increased travel speeds possible Less stopping and starting (positive and negative) Less congestion • Higher travel speeds Can raise concerns is What are we doing? What more can we do? What are the limitations? CONGESTED CORRIDORS • Current efforts — Signal Coordination Projects ' Edinger ' Warner ' Magnolia ' Brookhurst ' What more can we do? ' Develop/lead new coordination projects(PCH, Beach, Bolsa Chica others) ' Explore new technology(adaptive signals,connected vehicles) ' Isolated modifications to improve intersection efficiency • Limitations & Challenges? ° Caltrans control of Beach and PCH—cooperative effort needed ° Funding availability for improvements ° I-405 project influences—short and long term ,8 ISOLATED INTERSECTION CONGESTION • Current efforts ' Limited pursuit of capacity improvements ' Plans completed for Beach/Warner and Brookhurst/Adams • What more can we do? • Apply new technologies where appropriate/beneficial ' Pursue projects using Traffic Impact Fee funds 9/13/2019 ■ What are the limitations? Many key intersections are Caltrans jurisdiction(PCH and Beach) ° Funding 10 ■ Most intersections don't qualify for Measure M grant funding ■ Few intersections meet"below standard"level of service requirement ° Some Traffic Impact Fee money available, but limited ,s CURRENT AREAS IN DEVELOPMENT • Current Technologies in Development ' Adaptive Signal Controls • Upgraded Traffic Signal Controllers • Preparing for future of autonomous vehicles/intelligent vehicles • Coordinating Traffic Signals ' Current and new projects to improve coordination& infrastructure ' Magnolia& Brookhurst(current). ' Traffic Management Center upgrades • Warner, Edinger&Talbert(S61 Grants) ' Potential new projects • Pacific Coast Highway—significant planning with Caltrans • Staffing ° Filling additional traffic engineering position now ° Ability to more proactively address operational issues zo CURRENT AREAS IN DEVELOPMENT • 1-405 Freeway Project • Significant disruption to normal patterns for another 4 years • Potential to significantly alter local street patterns and relieve congestion on certain routes 21 SMART SYSTEMS/INTELLIGENT TRAFFIC SIGNAL • The Vision Create an integrated system of vehicles and street operations ■ Autonomous vehicles — self driving ■ Intelligent vehicles • Advanced sensor,warning&control systems • Vehicle to Vehicle&Vehicle to Infrastructure communication ■ Intelligent roadway system • Cross street sensor systems(crash avoidance) • Communication with signal controllers(e.g. , current indications,anticipate red or green lights) • Active communication of congestion and travel speeds • Incident warnings • Adapt operations to conditions • Transit priority 22 . . SMART SYSTEMS/INTELLIGENT TRAFFIC SIGNAL 12 • What is the current status? Rapidly changing/still developing Designing systems that are likely to meet future needs Some capabilities functional (e.g. adaptive controls) Analyzing infrastructure needs OCTA leading regional efforts ■ Needs ■ Funding 23 Thank you !
