Hearing Set For Roundabout For Four Corners
DAY
By Paul Petrone
Published on 6/14/2009
The state Department of Transportation will hold a public meeting Wednesday at 7 p.m. to give Salem residents a chance to voice their opinions on the proposed roundabout for Salem Four Corners. The roundabout, which would replace the current lighted intersection at Routes 85 and 82, would be a one-lane hybrid design, according to Will Britnell, the DOT's project manager. Currently, that intersection is one of the more dangerous in the state, Britnell said. By installing the roundabout, he hopes it will make the area dramatically safer.
”The studies show that roundabouts reduce accidents by 39 percent, injuries by 76 percent and fatalities by 90 percent,” Britnell said.
Britnell also points out that similar studies have shown that traffic moves faster through roundabouts than at intersections, reducing carbon emissions by 30 percent. While the roundabout would primarily have one lane, he said, there would be a separate lane for cars driving east on Route 82 and turning right onto Route 85, a common route for people coming off Route 11. There would also be a lane installed for commuters driving north on Route 85, according to Britnell. The roundabout would widen to two lanes until it unloads traffic on Route 85 north.
Three buildings would be removed to complete the roundabout, which would be located west of the original intersection, including the former Bad Boyz Toyz building and the adjacent vacated white house. The area will be cleared and converted into an open field leading up to the bank of Harris Brook. The third building that would be demolished would be the former general store in the Salem Town Marketplace, which is now Gin Seng Spa and Massage Parlor.
Gin Seng Spa would be forced to move, but the transportation and relocation fees would be paid by the state. Britnell expects the project, which is still in the conceptual design phase, would be built in 2012 and cost $2.75 million, all of which would be paid for by the federal government.
If there are no major, valid concerns brought up at the meeting by residents, the project will move from the conceptual design phase to the formal design phase, according to Britnell.

Byram residents to town: Fix our traffic circle

This wheel may need re-inventing.
A traffic circle built about a year ago at South Water Street and Mead Avenue in Byram is drawing criticism from residents, who say its flawed design cannot accommodate large trucks that frequently cause damage to the roundabout.
"This happens constantly," Susan Frano, who lives nearby, wrote in an e-mail to Eye on Greenwich.
Frano said it's been several months since a truck destroyed part of the curb of the traffic circle, where the town has since put up some orange cones and sawhorses.
Amy Siebert, the public works commissioner, said the town has located the culprit truck's owner and is waiting for his insurance to pay for the damage.
"Yes, we know there was some damage from a rogue truck," Siebert said. "We fortunately caught him."
Siebert contested claims that the traffic circle was poorly designed, however, saying it was never intended to accommodate all trucks.
"We do get some yahoo drivers," Siebert said. "It's up to these truck drivers that come with certain sorts of vehicles to take proper care when they're going through intersections."
Siebert said she would love for a neighborhood group to assume responsibility for the beautification of the center of the traffic circle.
Byram resident Chris Antonik echoed Frano's concerns about the traffic circle.
"When they built it, we knew that it wouldn't work," Antonik said. "That really disgusted me. It was a waste of our taxpayers' money."
Roundabout causes stir among residents
Stamford ADVOCATE

GREENWICH - Designed to ease traffic congestion from a new housing development, a roundabout on Havemeyer Lane is drawing complaints from residents. The roundabout is unsightly and may create backups on Havemeyer, which straddles the Stamford-Greenwich border, some residents say.
"We have been getting calls about it - did I know what was going on? Why did we do this?" said Diane Fox, Greenwich town planner.
Stamford and Greenwich officials agreed on the design as part of the settlement of a lawsuit involving the two municipalities over Palmer Hill, a 195-unit townhouse and condominium development on the former Cuisinart property at 77 Havemeyer Lane, Fox said. The developers are Buckingham Partners of Haddonfield, N.J., and Sun Homes of Pawling, N.Y.
"There's been a lot of history on this," Fox said. "It wasn't done quietly, by any means."
Officials were concerned about vehicles entering the road from the development and speeding, she said.
"This was felt to be a good traffic-calming device," Fox said. "It certainly forces us all to slow down."
Installed about two weeks ago, the roundabout collects traffic from Havemeyer Lane to the north and south, North Ridge Road to the west and the entrance of the housing development in Stamford to the east. Sam Romeo, a neighborhood leader, said drivers will bypass Havemeyer Lane for the more residential Florence and Old Orchard roads to avoid the roundabout.
"It's an absolute nightmare," Romeo said. "Even my wife, we had to get out to the Post Road, she said, 'You're not going through the war zone?' I think it's a big mistake."
Bob Dale, managing partner for Buckingham Partners, said the roundabout is under construction and won't be completed for about two weeks. A traffic light will be installed at Havemeyer Lane and Palmer Hill Road during the summer, Dale said. Developers were sensitive to effects on the neighborhood, he said.
"I think we've actually worked well with the neighbors," Dale said.
Selling for $500,000 to about $1 million, the units will be ready for occupancy in July, Dale said. Forty of the 195 units have been sold. Greenwich and Stamford will be responsible for plowing snow from the roundabout, though Havemeyer Lane often is cleared by Greenwich highway employees through an agreement with Stamford. Fox said Greenwich officials have limited authority over Havemeyer Lane because most of the street is in Stamford.
"People may think we own Havemeyer Lane. We don't. Only up to a certain point," Fox said.
Havemeyer residents back roundabout
Greenwich TIME

Published March 28 2006
In a show of hands at a public hearing last night, a majority of Havemeyer Lane area residents signaled their support for a town-designed roundabout for the busy artery to help mitigate the impact of a new housing development.
Unveiled by the town's traffic engineer and planner at a special meeting of the Board of Selectmen, the roundabout would collect traffic from Havemeyer Lane to the north and south, North Ridge Road to the west and the entrance of a 195-unit housing development in Stamford to the east.
The planned development, which is on the site of the former Cuisinart property at 77 Havemeyer Lane, has gained zoning approval from Stamford but has been tied up in litigation with Greenwich. Town officials, uncertain of the development's impact on the surrounding streets, want to have a hand in any changes to the traffic pattern.
"The roundabout would seem to be a very good safety measure," said Kathleen Saxon, a Northridge Road resident.
Saxon, like many of the 30 to 40 residents who attended last night's public hearing, called on officials to modify the design to include a one-way traffic restriction on her section of North Ridge Road so that cars would not be able to enter the cross-street from Havemeyer Lane.
But residents of some surrounding streets said the one-way restriction might increase traffic on their blocks, a warning echoed by town officials.
"Just remember, traffic is like water," Selectman Peter Crumbine said. "It's going to go somewhere."
First Selectman Jim Lash said the town would use the input from residents during its negotiations with the developer, Buckingham Starwood, in the legal case.
"We don't have a lot of leverage," said Lash, who cautioned that the roundabout design had to be accepted by the developer, as well as Stamford zoning officials. "In the end, this is in Stamford."

Abstract: |
To determine
whether a roundabout or an intersection would work best at a particular
location, it is important to know the number of vehicles making each
turning movement. Methodologies have been developed
for analyzing roundabout levels of service without knowing the detailed
turning movements. To analyze whether a roundabout or signalized
intersection would work better in a specific location, however, the
detailed turning movements are needed. A
methodology to determine existing turning movements at roundabouts with
minimal labor is presented. Using only four
persons, a typical four-leg roundabout can be counted, and all turning
movements (including U turns) can be
accurately estimated. The study to update the Master Transportation
