Maintaining the town of Southington’s road network requires short-term interventions and long-term planning. On the short-term side, whenever the town hears about an issue with a pothole or a damaged curb, the problem is added to a list and a crew dispatched to fix it once scheduling permits.
Then there is systematic maintenance. This long-term process involves mapping out deterioration, creating a ‘road list’ that describes the condition of every town road, then deciding what the most cost-effective treatment would be.
As recently as 2018 most of this assessment work was done in-house, with town employees surveying Southington’s roads and compiling a master list based on their inspections. The next year, however, Southington hired a vendor, City Logix, to do the job using car-mounted scanners and various automations.
Last year, Southington brought on a new firm, Hartford-based BETA Group, to perform this work. At the April 1 meeting of the Public Works Committee, BETA Senior Vice-President Anthony Garro gave a presentation on the technology and techniques his firm uses to assess Southington’s roads.
There are 314 miles of road in Southington: 209 miles of town road, and 105 miles that are either private or belong to the state. Last fall, BETA sent out vehicles to scan every square foot of the town’s network.
BETA’s distinctive blue vehicles, which are shown in the headline photo, resemble Google Street View cars and are equipped with video cameras that take a snapshot of the road every 20 feet. In addition, LIDAR devices measure the shape of the road’s surface, identifing cracks and depressions. LIDAR, which stands for ‘Light Detection and Ranging,’ is a technology that uses a laser to measure the distance between the detector and the road with centimeter-level precision, and a computer to turn those measurements into a surface map.
Once combined, the video and the LIDAR data are employed to assign a grade to the condition of every 20-foot stretch of road. BETA’s grading system runs from 0 to 100, ‘failed’ to ‘good’. To ensure quality control, human evaluators are send out to double-check selected spots. Garro said that machine evaluations agree with human evaluations 85% of the time.

Garro showed the committee some illustrations of different grade ranges. White Oak Drive and Franklin Street were rated ‘good’ with scores of 99 and 90, respectively:

Patridge Drive and Merrell Avenue were ‘fair’ (77 and 57):

while a section of Atwater Street and Vermont Court were graded ‘poor’ (48 and 17):

Garro said that the overall grade for Southington’s entire road network, 72.78, is above average for towns in the area, which means that it has a handle on its problems and is not seeing deterioration run ahead of repair efforts.
These grades are made available to the town through a dashboard called Manage My Roads. The dashboard also presents a range of remediation options which vary in cost and durability – everything from crack sealing to full-depth reclamation. Different situations call for different approaches: it would, for example, make no sense to tear up and reconstruct an entire road just because it had a single small crack, or to spot-treat a road with tar that was heavily potholed. For each problem, there are one or treatments that make the best sense in terms of cost and effectiveness. BETA software does cost-benefit analyses for each stretch of road to show which technique makes the most economic sense.
How does this benefit residents? Road fixes are slow and expensive, and the budget for them is limited. According to BETA’s report, it would cost $38,350,000.00 to fix all of the town’s roads. The town’s actual plan this year is to spend about one-tenth of that, $4,197,457.32, on remediation from a pot of capital improvement funds. This sort of prioritization ensures that the town gets the most value for its money.
The town plans to target 8.91 miles worth of roads with systematic fixes this year. The stretches of road are shown in green in the following images. One cluster of roads is in the southwest corner of town near the intersection of I-84 and Rt. 322:

There is a second cluster just east of downtown, and a third cluster east of Hatton School:
