Final Preliminary Route 122-140 Traffic Study Town of Grafton Prepared in conjunction with the Central Massachusetts Metropolitan Planning Organization (CMMPO) Transportation Management Systems Programs December 2005 The preparation of this document has been financed in part through a grant from the U.S. Department of Transportation, Federal Highway Administration, under Contract #4034019 with the Massachusetts Highway Department. FINAL Preliminary Route 122-140 Traffic Study EXECUTIVE SUMMARY The transportation staff of the Central Massachusetts Regional Planning Commission (CMRPC) recently conducted a traffic study on the joint section of Route 122-140 in the town of Grafton. This study was recommended in the earlier Blackstone Valley Corridor Planning Study (BVCPS), completed by the CMRPC staff in September of 2003. The study focused on the length of Route 122-140 from Quinsigamond Corner in North Grafton to the Carroll Road intersection at Lake Ripple. The study reviewed current travel conditions along this section of state highway and also examined projected conditions over the next decade. Suggested improvements for the town’s consideration are summarized below: Maintenance • Maintain all traffic control signals, signs and pavement markings • Selectively cut back overgrown vegetation • Clean culverts under Route 122-140 • Be mindful of unsignalized intersections with local streets Monitoring • Monitor new traffic signals in the Quinsigamond Corner area • Assess the requirements for signalized control at local residential streets Wheeler Road and Snow Road/Harris Road • Monitor commercial area traffic signals at the Shopping Plaza Drive and the Route 122/Route 140/Carroll Road intersection • Conduct Travel Time & Delay Studies under CMRPC’s ongoing Congestion Management System (CMS) activities • Working with MassHighway, monitor pavement distress - consider a pavement reclamation project when deemed necessary Short Term Improvements • Remove the “Stop” sign from Route 122 northbound at the Route 122/Route 140/Carroll Road intersection-replace with a “Stop Here On Red” regulatory sign 2 • Improve the Route 122-140 northbound lane drop zone north of Carroll Road through improved pavement markings and signage. Geometric improvements could include limited roadway widening • Consider the consolidation of curb cuts Longer Term Improvements • In the future, it may become prudent to restrict left hand turning movements at various locations • Preserve the existing 2-lane roadway cross-section through the largely residential area between Quinsigamond Corner and the Harris Road/Snow Road intersection • Consider limited roadway widening through the commercial segment between the Harris Road/Snow Road intersection to the Route 122/Route 140/Carroll Road intersection. Roadway widening to accommodate a 4-lane cross-section option, if acceptable to the community, would improve operations from the LOS “D-E-F” range to LOS “A-B-C” range. With this option, the lane drop will still exist at the Harris Road/Snow Road intersection. (Although a 3-lane cross-section option, with a center Two Way Left Turn Lane [TWLTL], was analyzed, MassHighway has commented that current and projected daily traffic volumes along the common section of Route 122-140 exceed the theoretical capacity for such an alternative.) • Contiguous sidewalk along at least one side of Route 122-140. Consider some type of pedestrian screening at MassPike (I-90) overpass • Consider a coordinated landscaping/streetscape effort, especially along the commercial segment between the Harris Road/Snow Road intersection and the Carroll Road intersection at Lake Ripple. ________________________________________ Review the entire traffic study at www.cmrpc.org or simply drop by the Grafton Public Library at the town common or the planner’s office in the town hall to obtain a copy.
