Traffic Q&A: Why do the signals seem so out of sync at Meridian and Fifth Avenue in Puyallup?

No comments

Q: Why do the traffic signals at Fifth Avenue Northwest and the Meridian/Second Street couplet in Puyallup seem so out of synch? – Janet W., Puyallup

A: First, let us set the scene.

The main north-south drag through the heart of Puyallup is the Meridian/Second Street couplet.

Meridian is one-way southbound. Second Street (and sometimes Third Street) is one-way northbound.

Now Fifth Avenue Northwest crosses both stems near Grayland Park.

Got it? Good.

We will let Janet, who frequently drives on Fifth Avenue Northwest, take it from here.

In|Sync reduces travel times on Rosecrans in Midway District

No comments

A new automated traffic-signal optimization system on Point Loma’s Rosecrans Street was officially dedicated March 24 by Mayor Kevin Faulconer and Peninsula leaders.

Faulconer said the city’s “made a concentrated push in the last few years to use techology to become a smarter city trying to use that technology to provide better service to customers and to our residents. … Now we’re using technology to improve traffic.”

The mayor noted the new signals “communicate with each other, memorize traffic patterns and make timing adjustments so cars keep moving along rather than sitting at a red light for minutes on end.”

The new system “is all about taking real-time data, and turning it into real-time results,” said Faulconer.

New Innovative Technology Optimizes Traffic Signals, Reducing Travel Time Thanks To $600,000 State Grant

Thursday, March 9, 2017 – NEWS RELEASE

San Diego – With the goal of making a smarter and cleaner San Diego for future generations, Mayor Kevin L. Faulconer was joined today by City Councilmember Lorie Zapf and community leaders to tout the successful installation of adaptive traffic signals in the Point Loma and Midway neighborhoods that have significantly improved traffic flow and reduced vehicle stops.

Through a $600,000 state grant, the City of San Diego installed 12 “Adaptive Traffic Systems” along the Rosecrans Street corridor from Hancock Street to Nimitz Boulevard as a quality-of-life improvement for neighborhood residents. These smart traffic signals communicate with each other and adjust signals, memorize traffic patterns, improve traffic flow and reduce vehicle stops.

“We’ve made a concerted effort over the past few years to improve neighborhoods by installing smart infrastructure along some of San Diego’s most congested roadways,” Mayor Faulconer said. “Everybody hates sitting in traffic so we’re turning to new technology to solve this age-old problem. These smart signals adjust traffic lights to keep cars moving rather than sitting at stoplights.”

Mira Mesa Phase I Adaptive Traffic Control System Wins Award

No comments

Location: City of San Diego – Mira Mesa Community

City or County Responsible for Project: City of San Diego

Award Category: Safety or Intelligent Transportation System Projects

Narrative Description Of Your Entry:

Mira Mesa Phase I adaptive traffic control system, activated in Summer 2016, is the City of San Diego’s most complex system deployment. Project goal is to improve traffic flow, reduce travel times, reduce greenhouse gas emissions, and enhance safety in one of the most traffic-congested communities in San Diego. To meet these goals, the City of San Diego selected the most advanced adaptive traffic control system currently on the market: InSync. Mira Mesa Phase I adaptive traffic control system deployment was designed to tie into initial InSync deployments on Lusk Boulevard, which involved nine intersections and public/private funding. Successful deployment of the Lusk Boulevard system, which reduced travel times by 24 percent, reduced stops by 61 percent, and reduced fuel consumption by 24 percent, caused the City to expand use of adaptive traffic control systems, including to other intersections in west Mira Mesa.

Smarter traffic signals

No comments

SIOUX FALLS, S.D. (KELO AM) – The city is equipping more streets with adaptive signals that detect traffic counts and adjust signals in real time.

Dustin Brinkman with Rhythm Engineering says the technology has mad a positive impact to traffic flow on 26th Street, reduced crashes and decreased fuel consumption.

Sioux Falls Police Chief Matt Burns says when cars stop less often, the likelihood for crashes also decreases.  He says “more smoothly flowing traffic makes for safer commutes and a healthier community.”

Traffic snarls go bye bye bye with InSync system

Tired of gridlock on Rosecrans Street and throughout the Peninsula?

Relief is on the way soon in the form of an InSync traffic optimization system now being installed on signals along Rosecrans, one of San Diego’s busiest and most congested thoroughfares. A similar traffic- optimization system was installed six months ago on Torrey Pines Road on La Jolla Parkway in “the Throat” in between Interstate 5 and La Jolla Village.

“This is the same signal-optimization technique,” said Duncan Hughes, a city senior traffic engineer, who noted, “Rosecrans in Midway is among the heaviest-volume roads (in the city), not just Rosecrans, but all the crossing arterials.”

New Synchronized Light System in Place on Newtown Bypass (PennDOT)

No comments

A synchronized traffic light system was put into operation on the Newtown Bypass Tuesday, police confirmed, saying it will be “fine-tuned” through the end of the week.

The PennDOT project to install the light system, called InSync and created by Rhythm Engineering, will improve traffic flow by taking into account the volume of cars traveling on the bypass at one time, officials have said.

In|Sync on Route 22 gets Glowing Early Returns (PennDOT)

No comments

It has been nearly two months since traffic lights at 18 intersections along Route 22 between Murrysville and Monroeville were fitted with a radar detection system to keep traffic moving without heavy backups.

Statistics from a study done by the company that installed the system shows it is doing what it is supposed to do:

• A 20 percent reduction in westbound traffic delays during the morning rush hours.

• A 34 percent reduction in eastbound traffic delays during the afternoon rush hours.

• An overall 13 percent reduction in delays over the course of an average day.

The study compared traffic for two weeks before and after the InSync system was put in place in mid-February by the Kansas company, Rhythm Engineering.

Rhythm Engineering Working Behind the Scenes to Make Sure KC Streetcar Traffic Flows Smoothly

No comments

When the Kansas City Streetcar launches in early May, a state-of-the-art computerized traffic system will also kick in to make sure everything flows smoothly.

Reggie Chandra, founder and CEO of Rhythm in Lenexa, Kansas, said the computer system is called In|Sync.

“The System of 21 cameras along the route feed the computer information about cars, how long they have been waiting at the intersection, the streetcar location and whether or not the pedestrian button has been activated. The computer will then analyze that information and determine the best option to keep traffic moving through the intersection,” said Chandra.

The streetcar does not get an automatic green light at intersections. However, the computer program does give the streetcar a higher priority because more people are on board. Sometimes motorists will be stopped and sometimes the streetcar will have to stop. The traffic light control system is designed to keep all traffic flowing.
