CONNstruction - Fall 2015 - (Page 22)

feature Intelligent Communication in TRANSPORTATION By Gail Short In Connecticut, drivers traveling on the I-84 corridor between downtown New Britain and Hartford often experience brutal traffic jams during their morning and evening rush hour commutes. But on March 28, 2015, the state, in an effort to ease traffic congestion, launched a new Bus Rapid Transit (BRT) system called CTfastrak. The CTfastrak system features low-emission, diesel electric buses that travel between Hartford and New Britain along a two-lane roadway dedicated exclusively for BRT vehicles. The bus route has just 10 station stops, approximately one stop per mile, so commuters, for just $1.50, can bypass the rush-hour traffic, avoid making multiple bus transfers, experience shorter wait times and reach their destinations faster. Since its debut, CTfastrak averages 14,000 riders a day, according to state officials. CTfastrak buses are equipped with a sophisticated, state-ofthe-art wireless network communications system constructed by McPhee Electric, Ltd. McPhee, which is based in Farmington, specializes in sophisticated electrical design and construction solutions for commercial enterprises, electric utilities, government and educational institutions. The state hired McPhee to build an Intelligent Communications System for CTfastrak. The work included designing, constructing, installing and testing a 48-strand, fiber optic cable that is the backbone of the BRT's communication infrastructure. McPhee was the prime contractor for CTfastrak directly responsible for functional system operation including all software and communications hardware at the stations and in the buses. "A 22 / CONNstruction / FALL 2015 complete functional systems test had to be performed at McPhee's prefab and testing facility in Farmington prior to installation in the field," says Brian Parent, McPhee Executive Project Manager. "This presented a tough challenge for us, since the 13-mile long fiber system is completely redundant and requires independent paths in and out of each station with a minimum number of splices." The cable supports a 10-gig network for all of the systems that are on the platforms that control communication along the CTfastrak system, Parent says. McPhee started work on the project in September 2013 and it took months of pre-planning, says Parent. "Even before we were awarded the contract to start, we had 12 meetings with the DOT and CTfastrak Transit from May to August of 2013 just to get the conceptual design and all of the pieces
