• State Route 39, owned and maintained by Caltrans

• 21 centerline miles

• Six to eight-lane facility

• 70 signals, were controlled by 170 Controllers

• 8 cities (La Habra, La Mirada, Buena Park, Anaheim, Stanton,

Garden Grove, Westminster, Huntington Beach)

• 4 freeway interchanges (I-5, SR-91, SR-22 & I-405)

• 60,000 ADT

• Over 2,500 vph each direction during peak hours

• Twisted pair copper interconnect installed 20 years ago

• Named first “Smart Street”


• Improve travel time, stops, fuel consumption,

pollutant emissions

• Install CCTV cameras at 14 ints.

• Provide real-time video transmission to CT D12

TMC using existing Copper interconnect

• Enable remote monitoring & control of traffic

signals from CT D12 TMC

• Upgrade controllers

Project Objectives:


• Desired upgrade to fiber optic cable – prohibitive due

to high cost

• OCTA budget = $1.3 million

• Solutions:

Reused existing 12 pair#19 Copper I/C

Implemented Ethernet-over-Copper technology

Good quality video image at a lower cost

Resulted in $700,000 savings

Overcoming Design Challenges:

+ Communications Network

• Issues with reusing existing cables:

Conditions of cables

Quality of video transmitted over copper

• Solutions:

Field conductivity test of existing cables

CCTV bench test

+ Conductivity Test

• Tested entire corridor, segment by segment

• All but one segments passed - Interconnect

conduits damaged

• Replaced 2,000 feet of the damaged I/C

cable and repaired the conduits at 2 break

points

+ CCTV Bench Test

• Bench test to simulate field conditions

• Utilize actual field devices, and over one mile

of copper cable

• Results

Good video quality from 500 kbps to

3Mbps speeds

Negligible latency in video transmission

+ CCTV Bench Test – Set up

+ Project Benefits Beach Boulevard (SR-39) Corridor





Corridor Synchronization Performance Index (CSPI)

• Index based on additive scores of average speed,

number of greens per red and number of stops per

mile

• CSPI < 70 (Grade C) indicates a need for

improvement

+ Lessons Learned

All Regional Traffic Signal Synchronization Programs lead to B/C Ratios of over 15:1

Corridor based vs Network based

Corridor based lead to reducing marginal benefits for later corridors

Network based require different jurisdictions to agree to a common cycle length within each sub-network

Hardware or no Hardware Upgrades

Many cities need to upgrade their traffic control hardware

GPS clocks is a basic necessity

+ Lessons Learned

Monitoring or Not?

Monitoring is very important to maintain the benefits

New developments, traffic growth, roadway infrastructure changes all affect signal timings

Orange County allows 2-year monitoring and corridors become eligible for funding application again after 3 years

Importance of Public Education

Public perception of improvements

Need to promote public awareness

Printed ‘fact sheets’

Council presentations

+ Lessons Learned

Most Cities need Traffic Operations and Hardware Maintenance Upgrades

Large cities have dedicated staff for traffic operations and maintenance – however, their staff may not be abreast of latest technological advancements

Mid-size and smaller cities do NOT have staff

Traffic Operations is often a part-time job

Maintenance usually by third-party

Need a lot of traffic operations and maintenance help

Design-bid-build vs Design-build

Many contractors are not familiar with the various hardware and signal systems

Design-Build often the best method
