• 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.

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

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

• perations across jurisdictions
• Arterial Management:

Improve traffic flow within the corridor during normal

• perations

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

• f signals between

agencies during incidents

16

• Managed by single countywide

traffic signal system (KITS)

• Model 2070 and ASC/3 controllers
• Extended communications

network to local traffic signals

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
• n 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
• perations
• 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
