The often repeated claim during the meeting that traffic on 413 will be slowed down by one second is also preposterous. Given the above statement, it defies common sense. The traffic study mentioned above, which PennDOT received as it commented on it in the press) clearly laid out the methodology of the study for all to see and comment, The answer to the question on YOUR methodology was that it will be added to a technical addendum later on and will not be subject to comment. Given the distrust that many residents have on what PennDOT is claiming, wouldn’t transparency on how you came to the conclusions of less traffic (yet reduced by one second!) on 413 help? A cynical mind would suggest that only faulty research needs to be hidden where critical analysis is avoided.

The often repeated claim during the meeting that traffic on 413 will be slowed down by one second is also preposterous. Given the above statement, it defies common sense. The traffic study mentioned above, which PennDOT received as it commented on it in the press) clearly laid out the methodology of the study for all to see and comment, The answer to the question on YOUR methodology was that it will be added to a technical addendum later on and will not be subject to comment.

The traffic study will be made available to the public at the time of the Environmental Assessment document publication or sooner, when available.  Previous versions of the traffic analysis were reviewed by third party engineers.  The study was also provided to SAFE Engineering for their review and comment; however, PennDOT did not receive any comments regarding the traffic analysis. 

PennDOT has requested Langhorne Borough to provide any traffic analysis completed by their engineers that may contradict their findings.  To date, no independent traffic analysis has been received.  Any safety analysis received from Langhorne Borough’s engineers has been found to have a lower reduction in crashes when compared to the current preferred alternative.

The PM Peak at the SR 213 (Maple Avenue) and SR 413 (Pine Street) is modeled to be approximately 1 second longer in intersection delay (31.0 seconds in the no build condition versus 32.5 in the build condition) for the overall intersection. Some approaches will experience less delay while others will experience slightly more due to changes in traffic patterns and optimizing signal timings and coordinating with adjacent signals, but the operations at the intersection as a whole are not expected to be majorly impacted versus the existing condition.
