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 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 non- recurrent 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

Field Elements Trailblazer Signs  2-Line with up to 6 characters per line (2.5’x4’) Dynamic Message Sign (DMS) combined with static route shield  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
