The Real Deal on Traffic Light Synchronization in Irvine!

I often get questions from Irvine residents about traffic light synchronization. To help answer these questions, I enlisted the help of my appointee to the Irvine Transportation Commission, Ken Montgomery.

Irvine Transportation Commissioner Ken Montgomergy

Ken knows more about these matters than just about anyone.  He is a retired civil engineer with more than 40 years of experience in managing public works and traffic and transportation issues. He served as Director of Public Works for three Southern California cities: Norwalk, Redondo Beach, and Laguna Niguel.

Ken retired from the City of Laguna Niguel in 2009 after 18 years as that City’s first Director of Public Works/City Engineer.

Ken has been closely following transportation and traffic issues in Irvine for decades and has served as a member of the Irvine Transportation Commission since it was re-established in May 2017, initially as its Chair.

Here is what Ken has to say about traffic light synchronization in Irvine:

Traffic Light Synchronization in Irvine

Ken Montgomergy

City of Irvine Transportation Commissioner

Overview

The City of Irvine owns and operates over 370 traffic signals.

All of the city’s traffic signals on the major corridors in Irvine are already synchronized.

There are another 40 Traffic signals at freeway on and off ramps that are owned and operated by Caltrans.  Those 40 signals are in the process of being upgraded so they can be coordinated with Irvine’s signals on those specific corridors.

What is Traffic Signal Coordination?

Traffic Signal Synchronization is a traffic engineering technique of matching the green light times for a series of intersections to enable the maximum number of vehicles to pass through, thereby reducing stops and delays experienced by motorists.

Synchronizing traffic signals ensures a better flow of traffic and minimizes gas consumption and pollutant emissions.

Driving on a corridor that is synchronized does not means that a driver will get all green lights. Rather, the system attempts to maximize the efficiency of the system favoring the heaviest traffic directions depending on the time of day.

For instance, Jamboree Road traffic is twice as heavy in the southbound direction in the morning compared to morning northbound traffic. The synchronization system sets the timing to favor the southbound direction in the morning. The opposite occurs in the evening peak period when north bound Jamboree traffic is much heavier than the southbound traffic.

Irvine’s Traffic System

The City operates 19 synchronized traffic signal systems that are currently not coordinated with the Caltrans signals. Within the next 12-18 months, the Caltrans signals will be coordinated with the City’s synchronization program, which will considerably help traffic flow on those corridors.

These 19 synchronized traffic signal systems crisscross each other, which means that two heavy traffic corridors are competing for the same green light time.  Also, heavy left turn demand at intersections limits the amount of green light time available for through traffic.  In addition, timing plans for these corridors can get out of date as traffic patterns change all the time. The city is constantly taking new traffic counts and making adjustments to the synchronization plans.

Traffic signal equipment also gets old and obsolete, so the city typically upgrades all the equipment and recalculates the timing plans on three or four corridors per year. These updates also involve adjacent cities so the synchronization program can operate across city lines.  For example, we currently have two synchronization projects underway with the City of Tustin.

The City of Irvine has a traffic signal control center at City Hall, called the Irvine Traffic Research and Control Center (ITRAC) that monitors those 19 synchronized corridors with video detection.  ITRAC is staffed by traffic engineers from 6:00 a.m. to 8:00 p.m.  When there is a construction project or a utility repair or a traffic accident that takes out a lane, staff modifies the signal timing to prevent a major back up in the direction where the constriction is taking place. Only Irvine and Anaheim have this type of traffic signal management center in Orange County.

There are three periods during the day when these 19 corridors are synchronized, the AM peak period, the mid-day peak period and the PM peak period. The hours of operation of those three periods varies from corridor to corridor. Corridors are typically not synchronized on weekend days except when there is a special event.  When a corridor is not is the synchronized mode, traffic signals operate independently within certain pre-programmed parameters. Traffic signals detect the presence of vehicles and bicycles all around the intersection and allocate the green light time as necessary.

Reporting a Problem

If you ever observe a traffic signal that you think is not functioning properly, call ITRAC and report it.

Their direct line is 949 724-7324.  Just tell them what you observed at a specific traffic signal and they will check it on the monitors and fix the problem if necessary. Traffic signals are complicated systems and require constant observation.

I know we would all love to have green lights all the time, but that is just not reality.  If it were, we would implement the “All Green Light Plan” — as would every city.

 

Bicycling in Irvine — Great Trail System, But Where to Lock-Up?

By  Ken Montgomery

Chair, Irvine Transportation Commission

Irvine Councilmember Melissa Fox appointed me to the City’s new Irvine Transportation Commission in May of 2017.  One of the missions of the Transportation Commission is to the advise the Planning Commission and the City Council on the traffic impacts of new development applications.

Another task for the Commission is to work with City staff on ways to improve traffic flow in Irvine.

Ken Montgomery Chair, irvine Transportation Commission

One way to reduce single occupant vehicle trips in Irvine is to increase the amount of people who will use a bicycle for their short trips around town when it is practical.

Irvine has the best bicycle trail system of anywhere in Orange County — it’s not even close.

Most of Irvine’s streets have bicycle lanes. Most of Irvine’s traffic signals have video detection cameras mounted on the mast arms. These cameras detect when there is a bicycle waiting at the red light. You don’t even have to push the bicycle push button anymore if you don’t want to. In Irvine you can legally ride on sidewalks, but you must yield to pedestrians. Thus, on the few streets where there are no bike lanes, you can ride on the sidewalks legally.

I ride all over Irvine everyday on my electric bike and I can get to every place in Irvine conveniently.

I know there are a few streets that have no bike lanes with narrow sidewalks like MacArthur near the airport, but for the most part I can ride a bike to any shopping center, professional office building, or recreational center or park in town.

The problem comes when you try to lock up your bike at one of these destinations!

Many private properties with big parking lots for cars have no bike racks. I frequently have to lock up to a handicap parking sign pole or a trash can with openings big enough for my cable bike lock.  Sometimes a destination will have a bike rack somewhere out of view, where no one can see the bike thief with the bolt cutters. This lack of bicycle parking often defeats the purpose of riding a bike if you can’t secure it properly.

The City requires new developments to have bike racks, but these racks often disappear after a few years or are relocated to an out of the way location. I feel that if I ride a bike, I should be able to lock up close to the building’s entry, not 500’ away.

The City is making efforts to get businesses to voluntarily provide bike racks near their building entries, but with over 25,000 businesses in Irvine, progress will be slow.  I encourage bike riders to let the business that you visit on your bike know that well placed bike racks is the “right thing to do” on many levels (customer service, environment, health).

The Transportation Commission meets the 1st and 3rd Tuesday of each month in the City Council Chambers at 5:30 pm.  I strongly encourage Irvine residents to bring any traffic concerns, ideas or comments to the Commission meeting.  You will be welcomed to speak at the beginning of the meeting.  The full City traffic engineering staff attends these meetings and they will hear your ideas and can respond to your questions.  Check here for Transportation Commission agendas.  The public is welcome to speak on all agenda items as well as non agenda related comments.

If you can’t wait for the next meeting, feel free to email me your questions, comments and ideas about transportation and traffic in Irvine.  I will forward your comments to the appropriate City staff member.

Let’s work together to improve Irvine’s traffic and make Irvine an even better place to ride our bikes!

Thank you for the privilege of serving the residents of Irvine.

Watch My Town Hall Meeting!

I held a public Town Hall Meeting at the Irvine Championship Stadium in the Great Park on Saturday, October 21, where we discussed traffic, childcare, the Southern California Veterans Cemetery, affordable housing, and other issues of interest to Irvine residents.

I was joined by several of my city commissioners, as well as by members of the Irvine Police Department, who were also there to answer questions.

Several dozen Irvine residents spoke and asked questions, and I thank everyone who attended.

Here are some photos from the event:

I really enjoyed the open, public dialogue with Irvine residents, and I intend to make these Town Hall Meetings a regular part of my work as an Irvine City Councilmember.

City Councilmember Melissa Fox Appoints Traffic Expert Kenneth Montgomery to Irvine’s New Traffic Commission

I am pleased to announce that I have selected Kenneth Montgomery as my appointee to Irvine’s new Traffic Commission.

Kenneth Montgomery is a retired Civil Engineer with more than 40 years of experience in managing public works and traffic and transportation issues as Director of Public Works for 3 Southern California Cities: Norwalk, Redondo Beach, and Laguna Niguel.  Ken retired from the City of Laguna Niguel in 2009 after 18 years as that City’s first Director of Public Works/City Engineer.  He has been closely following transportation issues in Irvine for decades.

I am delighted that Ken Montgomery will be contributing his expertise and insights to fixing Irvine’s traffic problems and building a transportation system that will serve Irvine in the 21st Century.

When I ran for election to the Irvine City Council, I promised to reduce Irvine’s traffic congestion both in the long and short term, while providing more transportation choices for Irvine’s residents and commuters, and to reduce travel time, reduce noise, improve safety, improve resident access to employment and entertainment centers, improve parking and reduce emissions. Ken Montgomery is also deeply committed to these goals – and he has the expertise, experience, and vision necessary to achieve them.

As Laguna Niguel’s Director of Public Works/City Engineer, Ken managed transportation and traffic issues for this new and developing city, including hiring the traffic engineering staff and managing their Transportation Commission.  He has also worked with Caltrans for years on redesigning freeway interchanges to minimize impacts on city streets.  Ken is an expert on traffic control devices such as stops signs, new traffic signals, street striping changes and school zone traffic management, and has designed and implemented dozens of major and minor street improvement projects to improve traffic safety, capacity and traffic flow.

Ken is a strong advocate for increased transportation choices as a means of traffic reduction.  He was instrumental in building train stations in each of the cities he has served.  He was personally responsible for the Metrolink station that serves Laguna Niguel/Mission Viejo, and has worked closely with the Orange County Transportation Authority (OCTA) on the bus lines and bus stops and shelters that serve Laguna Niguel.

He is also an avid bicyclist, who knows and champions the Irvine bike trail system.  Like Councilmember Fox, he is an advocate for making bicycle commuting safer and more practical.

Ken holds a degree in civil engineering from the University of Wisconsin, Madison. He and his wife Judy have resided in Irvine for 37 years and have lived in the same Woodbridge home since 1980.

Ken is an active member of Irvine Rotary Club and serves on its board.  He is also an Irvine CERT member, has served on the Arborlake Home Owners Association Board of Directors, and was a volunteer for the two Solar Decathlons held in Irvine’s Great Park.

“I’m excited to seriously tackle Irvine’s traffic and transportation issues, “Montgomery said. “I look forward to working with Councilmember Melissa Fox, my fellow traffic commissioners, city staff, and all our community stakeholders in getting Irvine moving again.”

The first meeting of the Irvine Traffic Commission is scheduled for Tues., May 16, 2017 at 5:30 p.m. at the City Council chambers.  Like all Irvine commission meetings, it is open to the public.

Let’s Get Irvine Moving Again!

badtraffic.01

Just about everyone in Irvine agrees that our recent explosive residential growth has led to unprecedented traffic congestion.

mail-01And every candidate for Irvine City Council now promises to control over-development and keep our traffic moving.

But no other candidate has offered a practical, concrete plan to accomplish this goal.

The key elements of my traffic plan are:

– Provide immediate relief for Irvine commuters by speeding up road and street repairs and prioritizing improvement projects throughout the city.

– Ensure Irvine residents and commuters have access to multiple safe and efficient transportation choices, including automobiles, bicycling, walking, iShuttle, ride-sharing, streetcar, and student transportation to Irvine’s schools.

– Restore Irvine’s village planning model requiring that housing developments include grocery stores, shopping, entertainment and childcare within one mile.

– Aggressively push for Irvine’s fair share of transportation funds from local, state, and ederal agencies — make sure that Irvine gets our fair share of Measure M, Measure S and Measure T funds for transportation to start — and seek out grants for fuel efficient and clean transportation projects.

These are concrete and practical steps that can be taken right now to help get our traffic and transportation problems under control, unsnarl our roads and provide Irvine residents with more transportation choices.

We must do something effective now about Irvine’s traffic, not just appoint a bureaucratic traffic commission to kick the can down the road.

The Fox Traffic Plan will reduce travel time, reduce noise, improve access to employment and entertainment centers, improve parking and reduce emissions, and make our streets safer for children, bicyclists, pedestrians and motorists.

Your comments and questions are welcome.

Melissa Fox Announces Traffic Reduction and Transportation Plan for Irvine

melissa-irvinemap

Irvine has long been recognized as a national leader in city planning and innovation.

Unfortunately, Irvine has failed to properly plan for the tremendous increase in traffic caused by the city’s explosive recent growth.

As a result, Irvine residents have been forced to contend with unprecedented traffic congestion and less safe streets and roads.  Irvine’s traffic jams are not only frustrating, they are also a major contributor to increased air pollution, and that’s bad not just for our climate, but our health too.

My plan offers concrete and achievable recommendations to unsnarl our roads and make our city a better place to live, work and raise a family.

Here is the press release announcing my traffic plan:

Melissa Fox Announces Traffic Reduction and Transportation Choice Plan for Irvine

 IRVINE, CA        Irvine Community Services Commissioner and City Council candidate Melissa Fox announced today a Traffic and Transportation Plan for the City of Irvine. Fox said that her plan is designed to reduce Irvine’s traffic congestion both in the long and short term, while providing more transportation choices for Irvine’s residents and commuters. The Fox Plan is intended to reduce travel time, reduce noise, improve safety, improve resident access to employment and entertainment centers, improve parking and reduce emissions.

“My plan is designed to make our streets safer for children, bicyclists, pedestrians and motorists,” Fox said. “The residents of Irvine are exasperated by the tremendous increase in traffic in the last few years and rightfully infuriated by the lack of concern shown by the current City Council.”

The key elements of the Fox Plan are:

– Provide immediate relief for Irvine commuters by speeding up road and street repairs and prioritizing improvement projects throughout the city.

– Ensure Irvine residents and commuters have access to multiple safe and efficient transportation choices, including automobiles, bicycling, walking, iShuttle, ride-sharing, streetcar, and student transportation to Irvine’s schools.

– Restore Irvine’s village planning model requiring that housing developments include grocery stores, shopping, entertainment and childcare within one mile.

– Aggressively push for Irvine’s fair share of transportation funds from local, state, and federal agencies and seek out grants for fuel efficient and clean transportation projects.

“My plan offers concrete steps that can be taken right now to help get our traffic and transportation problems under control, unsnarl our roads and provide Irvine residents with more transportation choices.” Fox concluded. “The Fox plan will make Irvine a model of transportation efficiency and safety in the future.”

The Fox Plan is intended to be brought to the City Council for comment and consideration.
