California Department of Transportation (Caltrans) Overview Part of the California Government Executive Branch 12 Districts Encompasses nine Bay Area counties of: Alameda, Contra Costa, Marin, Napa, San Francisco, San Mateo, Solano, Sonoma, and Santa Clara 3,500 employees with an annual operating budget of $450 M 6,500 lane-miles of highways, including 420 miles of carpool lanes Seven toll bridges: Antioch, Benicia, Carquinez, Richmond-San Rafael, San Mateo- Hayward, San Francisco- Oakland, and Dumbarton 2
San Francisco Bay Area Average Delay by Day of Week & Time of Day (Congestion in the 3 rd quarter of 2010 has increased as compared to the same quarter in 2009) 3
California Vision for Mobility Caltrans Current Key Focus Areas Build-out State Traffic Operations System (TOS): System Monitoring Performance Measurement Incident Management Traveler Information Integrated Corridor Management Signal Coordination (adaptive) Ramp Metering HOV/Express Lanes Other 4
San Francisco Bay Area Transportation Management Center (TMC) Built in 1996 and 0perational 24/7 Jointly staffed by Caltrans, CHP and MTC/511 Aggressively monitors and rapidly deploys available traffic management and motorist information services. Enhances communication among stakeholders. Minimizes traffic congestion due to incidents, planned highway work, and major special events. 5
San Francisco Bay Area System Monitoring CHP CAD Incidents (per day) Total incidents reported 2,700 Changeable Message Signs Traffic hazard reports 660 Accident reports 340 Reports passed to Caltrans for review 300 Reports requiring action by Caltrans 50 CHP Incident Data & Freeway Service patrol Vehicle Detection Stations 24/7 Transportation Management Center CCTV Cameras 6

San Mateo Smart Corridor 8
Stakeholders Project Sponsor: City/County Association of Governments of San Mateo County (C/CAG) Stakeholders: Caltrans Metropolitan Transportation Commission (MTC) San Mateo County Transportation Authority (SMCTA) Cities of San Carlos, Millbrae, East Palo Alto, San Bruno, San Mateo, Redwood City, Belmont, Burlingame, Atherton and Menlo Park, County of San Mateo 9
Stakeholder Needs Mitigate Impacts of nonrecurrent traffic congestion on local streets due to major freeway incidents on US-101 Coordinated operations among agencies along US-101 and SR-82 (El Camino Real) corridor Remote management capability of traffic signals Ability to monitor traffic conditions and collect traffic data along corridor 10
Goals Traffic Incident Management: Proactively manage traffic already diverted from the freeway to minimize impacts on local arterials Interagency Coordination: Improve sharing of resources between agencies for more unified transportation management operations across jurisdictions Arterial Management: Improve traffic flow within the corridor during normal operations 11
Objectives US 101 Major Incidents: Caltrans to manage and optimize signal operations along predetermined routes to improve traffic flow during incidents to minimize impacts due to vehicles naturally diverting off the freeway Normal Operations: Allow the operations to be coordinated and jointly monitored to optimize traffic flow along El Camino Real and local arterials 12
Requirements Route guidance and traveler information Central traffic signal system for remote management Real-time access to video and data for monitoring Communication systems with minimal recurring costs Regional hub in San Mateo Police Department (San Mateo Hub) 13
Corridor Limits Stakeholders identified alternate routes known as Smart Corridor Routes 14
Project Elements Field elements: Traffic Signals (250) Trailblazer Signs (111) Arterial DMS (8) CCTV Camera Locations (80) Vehicle Detector Stations (43) Communications Field to San Mateo Hub San Mateo Hub to City Halls Fiber Backbone Wireless, Existing Copper TMCs Caltrans, San Mateo Hub, & other Virtual TMCs Regional Communications San Mateo Hub to TMC via Bay Area Regional Communications Network Systems Integration 15
Field Elements Traffic Signals Upgrades enable coordinated operations of signals between agencies during incidents Managed by single countywide traffic signal system (KITS) Model 2070 and ASC/3 controllers Extended communications network to local traffic signals 16
Field Elements Trailblazer Signs Display detour or alternate route guidance Special event route guidance Installed 200 to 400 upstream of decision points 17
2-Line with up to 6 characters per line (2.5 x4 ) Dynamic Message Sign (DMS) combined with static route shield Field Elements Trailblazer Signs Pole mounted cabinets for sign controllers 18
Field Elements Arterial DMS 3-Line DMS (4 x8 ) with 8 to 12 characters per line Deployed where more information is needed, upstream of interchanges and on State highways (El Camino Real and Woodside Road) Displays may include Traveler information and lane closures 19
Field Elements CCTV Cameras Fixed and Pan-Tilt-Zoom cameras Most cameras installed on traffic signal poles at Critical Locations Single and quad channel encoders 20
Field Elements Vehicle Detection Stations Loops (existing traffic signal advance loops) Solar Powered Radar Stations (Mid-Block) Purpose: Collect volume, occupancy and speed data throughout corridor Input for traffic response operations Detect congestion and incidents 21
TMCs Caltrans TMC in Oakland is the only 24/7, dedicated transportation management facility in Bay Area San Mateo Hub will function as backup TMC in the event communications to Oakland is lost Cities will employ Virtual TMCs Cities do not have a TMC City Staff to use Workstations at City Halls or Maintenance facilities to monitor Smart Corridor elements Proved the concept in the Demonstration Project 22
Systems Integration Integration of devices, communications networks, and traffic signal systems involves: Central traffic signal, video distribution, and sign control systems used by all agencies Integration of devices and communication systems into one system Development of incident response plans for the alternate routes 23
Operational Structure Normal Operations Agencies manage their respective traffic signals Shared access to CCTV and traffic data Caltrans implements normal routing information on TBS and ADMS Incident Operations Caltrans assumes temporary control of traffic signals along alternate routes to implement approved timing plans (Flush Plans) to utilize unused capacity Caltrans implements incident routing information on Trailblazer signs 24
Operational Structure 25
Stakeholder Cooperation Cities agreed to Caltrans executing incident response plans C/CAG single point of contact - represents local agency interests All cities signed MOUs San Mateo provided facilities for Regional Hub All traffic signals connected to same system & use compatible controllers Caltrans Camelion ITS (BAVU) video management system to provide access for all users Shared Maintenance: C/CAG to maintain new elements on local roads Caltrans to maintain new elements on State highways 26
Lessons Learned Select a Project Champion (C/CAG) Develop operations, ownership and maintenance agreements early Cities need to protect infrastructure Establish corridor-wide standards/platform Account for legacy systems near project area Early coordination with IT departments Separate field cabinets for ITS devices Install conduit systems when possible Go California Project (2006) purchased 20+ mile conduit system along El Camino Real (SR-82) which the Smart Corridor used for the fiber optic backbone Consider small initial phase for proof of concept 27
