Congestion Management Report F.E. EVERETT TURNPIKE (SOUTH), NASHUA Segment Length: 6.7 miles Number of Traffic Signals: 0 Daily Traffic Volumes: 60, 000-69,000 Number of travel lanes: 6-8 Analysis Period: June 2015 Roadway Class: I (Principal Arterial — Other Freeways and Expressways) The F.E. Everett Turnpike serves as one of the primary north- attractions, including the Pheasant Lane Mall, downtown south thoroughfares in southern New Hampshire for Nashua, and the commercial corridors along NH 101A and vehicular traffic by connecting the state’s three largest the Daniel Webster Highway. cities: Manchester, Nashua and Concord. Since the Turnpike runs 44 miles from the Massachusetts border to Concord, Due to its role as a commuting corridor, the F.E. Everett the portion within the Nashua Region was divided into 3 Turnpike is expected to have some degree of congestion segments (North from Exit 13 to 10, Middle from Exit 10 to during peak travel times. In addition to the high volume of 7, and South from Exit 7 to the Massachusetts State line) in cars at certain peak travel times, contributors to this order to comprehensively study congestion during peak congestion are segments where travel lanes vary from two to periods. three lanes in either direction, and toll plazas, which require drivers to slow their speed. The Southern segment is located entirely within Nashua and extends from Interchange 7 (NH 101A/Amherst St) to the The Turnpike is operated by the New Hampshire Department Massachusetts state border. This segment of the Everett of Transportation’s Bureau of Turnpikes. The department Turnpike overlaps with U.S. Route 3. Since this segment plans on implementing Intelligent Transportation Systems to connects South Nashua with Tyngsborough, Massachusetts, help monitor and alleviate congestion. it is a major commuting route for those working within southern New Hampshire and metropolitan Boston area. It is also a vital road for freight transportation and local Report, travel time runs and data analysis conducted by 2017 AM Peak Period Actual & Expected Travel Times Corridor Extents: F.E.

AM Travel Time Ratios (7:00am—9:00am) Corridor Extents: F.E. Everett Turnpike, Interchange 7 (NH 101A/Amherst St.) to Massachusetts State Line Travel Time Ratio A travel time ratio (TTR) compares the actual (measured) & expected (non- congested) travel times along a corridor. It is assumed that in non-congested conditions, motorists can travel at the posted speed limit. The actual time is the average of several travel time runs. The ratio between the actual time and the expected time would equal 1 for a non-congested segment. Southbound Congestion does not occur during the morning peak period between Interchange 7 and Massachusetts border, as indicated by Travel Time Ratios that are below the threshold of 1. On average, travel in the southbound direction on this segment of the F.E. Everett Turnpike during the morning commute takes approximately 49 seconds (11%) less as compared to free -flow conditions. Northbound Congestion does not occur in the southbound direction between the Massachusetts border and Interchanges 7 during the afternoon peak period, as indicated by ratios that are at or below the threshold of 1. On average, travel in the northbound direction on this segment of the F.E. Everett Turnpike during the morning commute takes approximately 56 seconds (13%) less as compared to free -flow conditions.

Everett Turnpike, Interchange 7 (NH 101A/Amherst St.) to Massachusetts State Line Travel Time Ratio A travel time ratio (TTR) compares the actual (measured) & expected (non- congested) travel times along a corridor. It is assumed that in non- congested conditions, motorists can travel at the posted speed limit. The actual time is the average of several travel time runs. The ratio between the actual time and the expected time would equal 1 for a non-congested segment. Southbound Congestion does not occur during the evening peak period between Interchange 7 and Massachusetts border, as indicated by Travel Time Ratios that are at or below the threshold of 1. On average, travel in the southbound direction on this segment of the F.E. Everett Turnpike during the evening commute takes approximately 50 seconds (12%) less as compared to free -flow conditions. Northbound Congestion does not occur in the southbound direction between the Massachusetts border and Interchange 7 during the evening peak period, as indicated by ratios that are at or below the threshold of 1.

Probe Travel Time Data Corridor Extents: F.E. Everett Turnpike, Interchange 7 (NH 101A/Amherst St.) to Massachusetts State Line Northbound Probe Travel Time Data Corridor Extents: F.E. Everett Turnpike, Interchange 7 (NH 101A/Amherst St.) to Massachusetts State Line Travel times from the National Performance Measurement Research Data Set (NPMRDS) are available for the entire extent of the F.E. Everett Turnpike. Weekday travel time data collected in 2015 along three TMCs located as shown in the left-hand figure are summarized by travel speeds. The percent of traffic traveling below the speed limit versus at or above the posted speed limit of 55 mph during the peak and off peak hours for each segment is graphed in the figures below and on the following page. The data indicates that, in general: The vast majority of both freight and passenger vehicles exceeds the posted speed limit Northbound traffic between exits 6 and 7 slows down during peak and off peak hours, but more traffic is moving above the speed limit than below. The 2015 weekday travel time data was also summarized by average travel speed by hour of day for all vehicle types (passenger and freight combined). The graphs below show that average speeds during the majority of the day are above 60 mph, with the exception of the northbound traffic between exits 6 and 7, which moves a little slower but still above the speed limit.

The 60 NPMRDS data are derived from instantaneous mph vehicle probe speed data supplied by a variety of 55 GPS devices carried by both trucks and cars. The data are supplied on a GIS roadway network, 50 which divides the NHS into directional road segments based on the Traffic Message Channel (TMC) standard.

Everett Turnpike serves as a major north-south thoroughfare for residents, commuters, and tourists in the Nashua region to travel within southern New Hampshire and to Massachusetts. The F.E. Everett Turnpike plays an important role as a connector between Nashua, Massachusetts, and the rest of New Hampshire. The homes, office parks, industrial parks, and retail activity that are accessed by this corridor contribute to the region’s diverse economy. Due to the high volume of goods, services, and people that travel along this corridor every day, projects that minimize congestion and increase traffic efficiency are essential. Projects There are several infrastructure projects along the F.E. Everett Turnpike that could impact the corridor. Within the Southern segment, the redesign of Exit 5 SB and the creation of Exit 36S could have major impacts on reducing congestion and aiding traffic flows in Nashua. The construction of the southbound off ramp at Exit 36 may result in a substantial reduction in traffic volume on Spit Brook Road east of the F.E.
