Message From Legislator John Kennedy
Friends,
It gives me great pleasure to announce the commencement of a safety improvement project to our district. Several years ago, a teenager on a bicycle was struck while attempting to cross the street resulting in a very serious injury. In an effort to address this issue, I have worked tirelessly to study and create a bill that would prevent another occurrence of this kind. At our most recent General Meeting, the Suffolk County Legislature voted unanimously (18-0) to pass IR 1380 – a project that will reconstruct the intersection of CR 16, Smithtown Boulevard and Gilbert Ave/Sheppard Lane to improve traffic flow and safety. This is a relatively high volume intersection with vehicles traveling at high speeds.
The Suffolk County Department of Public Works (SCDPW) retained the RBA Group to perform an analysis of existing traffic and safety conditions along the subject corridor and to develop engineering solutions that will result in improvements of the safety for all users, while minimizing impacts to the local community. Based on RBA’s analysis of accident and traffic data from the past three years, along with observations noted in the field, several recommendations were made to the County in regards to how to best accomplish our goal.
The study revealed compelling statistical information that further supports our need for this safety improvement. There were a total of 32 accidents in the three-year period between January 2007 and December 2009 along CR 16 within the study limits. The accident analysis showed that the most frequent type of accidents on CR 16 were rear-end, right angle, and overtaking. The contributing factors were often driver inattention, failure to yield right of way and excessive speeds; 85% percent of drivers in the study area were found to be in the range of 45-49 mph, considerably higher than the posted speed limit of 35 mph.
In addition to a statistical analysis, the RBA group also conducted a field observation. In the field, it was observed that eastbound and westbound vehicles on CR 16 routinely overtake left turning vehicles at the Gilbert Avenue/Sheppard Lane intersection, utilizing both the striped gore area and the shoulder area which leads to a number of narrowly avoided accidents.
The types of accidents that occur at the Gilbert Avenue/Sheppard Lane intersection are not those that would be corrected by a traffic signal. In fact, rear-end accidents, which are the ones most prevalent at this location, would typically increase with the installation of a traffic signal. In addition, it was determined that it is not feasible to redirect traffic from Gilbert Avenue, as it would create a negative impact on adjacent residential roadways. The accidents that occur on CR 16 can be avoided by measures that oblige drivers to reduce their speeds.
Three (3) design alternatives were developed for SCDPW’s consideration to mitigate the safety and geometric issues identified by the RBA group. Proposed elements include a variation of minor geometric modifications and traffic calming measures including: raised medians and islands, modifications to pavement markings, new signage, modifications to curb radii, new turn lanes, traffic management measures as well as a roundabout alternative. After careful consideration, we found it most sensible to adopt a design that will create center two-way left turn lanes to provide storage for vehicles and reduce rear-end accidents, create a left turn lane for westbound vehicles to enter Gilbert Avenue, create a raised center median west of Gilbert Avenue intended as a traffic calming feature to reduce vehicle speeds, as well as to create a curb extension to improve alignment of Gilbert Avenue with Sheppard Lane.
Currently, construction is set to begin within a few months and we hope to have the project completed by the end of the year. As always, public safety is at the forefront of our agenda and I will continue to remain diligent in my efforts to help improve our district and our county’s safety and quality of life. Please feel free to contact my office with any questions or concerns regarding this matter.
As always if you have any questions, please feel free to contact me at (631) 854-3735.
