Signal changes expected to improve Route 30 traffic flow

Traffic moves along Route 30 at the Penn Irwin Motel, which straddles the North Huntingdon-Irwin border. ,

Motorists traveling Route 30 in North Huntingdon and Irwin should see an improvement in the traffic flow on the heavily traveled roadway, especially during peak hours, as the township alters some of the signals.

The traffic signals will be adjusted beginning July 9 based on criteria such as traffic volumes, signal spacing, intersection geometry and other necessary factors to maximize efficiency under the project to coordinate the timing of the traffic signals and to upgrade the signaling equipment, said Michael Turley, North Huntingdon assistant manager.

The improvements to the equipment, including emergency vehicle pre-emption, have been installed at several intersections.

The changes will revise the traffic signal timing at 24 intersections, including six intersections with traffic signal sequencing changes.

Electronic message boards will be set in place, before the changes, to alert motorists, Turley said in a statement.

As recommended, “lagging left” signal phasing is being implemented at the intersections with signal sequencing changes.

The “lagging left” signal phasing means the left turn traffic phase will turn green after the through movement of the traffic, rather than before the through movement.

The result will be better synchronization of traffic flow on the highway, Turley said.

PennDOT is planning an estimated $60 million improvement project along a six-mile stretch of Route 30, from Irwin to Route 48 in North Versailles.

We moderate comments. Our goal is to provide substantive commentary for a general readership. By screening submissions, we provide a space where readers can share intelligent and informed commentary that enhances the quality of our news and information.

While most comments will be posted if they are on-topic and not abusive, moderating decisions are subjective. We will make them as carefully and consistently as we can. Because of the volume of reader comments, we cannot review individual moderation decisions with readers.

We value thoughtful comments representing a range of views that make their point quickly and politely. We make an effort to protect discussions from repeated comments either by the same reader or different readers

We follow the same standards for taste as the daily newspaper. A few things we won't tolerate: personal attacks, obscenity, vulgarity, profanity (including expletives and letters followed by dashes), commercial promotion, impersonations, incoherence, proselytizing and SHOUTING. Don't include URLs to Web sites.

We do not edit comments. They are either approved or deleted. We reserve the right to edit a comment that is quoted or excerpted in an article. In this case, we may fix spelling and punctuation.

We welcome strong opinions and criticism of our work, but we don't want comments to become bogged down with discussions of our policies and we will moderate accordingly.

We appreciate it when readers and people quoted in articles or blog posts point out errors of fact or emphasis and will investigate all assertions. But these suggestions should be sent via e-mail. To avoid distracting other readers, we won't publish comments that suggest a correction. Instead, corrections will be made in a blog post or in an article.
