Report: Installing traffic light at Maple and Sagamore streets in Manchester not warranted

MANCHESTER — Officials with the city’s public works department say traffic counts conducted at the intersection of Maple and Sagamore streets show installation of a traffic signal at that location is not warranted at this time.

After a van crashed into and destroyed the storefront of MS Market at 186 Sagamore St. in December — the fourth time the store has been hit by a vehicle in the last 10 years — store owner Syed ‘Tai’ Tahir began collecting signatures on a petition requesting the city look at installing a traffic light at the intersection.

The petition — signed by more than 300 customers and neighbors — was presented to members of the Aldermanic Committee on Public Safety, Health and Traffic last month.

Board members voted to direct the Department of Public Works to conduct a traffic study to determine if a signal is warranted.

On Tuesday, committee members heard the results of traffic counts conducted by public works personnel over a 12-hour period on January 16.

To meet the requirements for installation of a traffic signal, several traffic-related conditions must be met.

Since there are two thru-travel lanes on Maple Street and one lane on Sagamore Street, Condition A requires a minimum of 600 vehicles per hour on the major street and 150 vehicles per hour on the higher-volume minor-street approach. Based on the traffic data collected, Condition A was not met during any of the 12 hours traffic was monitored, since the volume on Maple Street never exceeded 600 vehicles per hour and the volume on the higher Sagamore Street approach never exceeded 150 vehicles per hour.

Condition B, interruption of continuous traffic, requires a minimum of 900 vehicles per hour on the major street and 75 vehicles per hour on the higher-volume minor-street approach. Based on the traffic data, Condition B also was not achieved during the traffic counts, since the volume on Maple Street never exceeded 900 vehicles per hour and the volume on the higher Sagamore Street approach never exceeded 75 vehicles per hour.

In all, nine traffic-related benchmarks were examined, and public works personnel reported none were met.

“Based on these findings, installation of a traffic signal is not warranted or recommended at this time,” reads the report presented to aldermen on Tuesday. The report recommends city officials consider conducting a speed study on Maple Street to determine if targeted enforcement is necessary.

Alderman Will Stewart, who represents Ward 2 where MS Market is located, thanked public works personnel for conducting the traffic counts.

“Approximately 300 customers of that store requested this,” said Stewart. “The analysis does not warrant a signal, but we will probably be coming back to this committee in the future with measures to slow down traffic on Maple. It remains a concern in the area.”
