units,number of employees or other quantitative measure. ,
TAp Generation provides trip rates for"Medical-Dental Office Buildings"(Land Use Code 720).
A 15,870 square foot medical office building is anticipated to generate 61 and 71 total trips '
during the weekday AM and weekday PM peak hours, respectively. The relevant information
taken from ft tion is contained on Appendix Sheets A-11 and A-12.
Trip distribution is the directional orientation of the new site traffic. In addition to '
providing
volume information,Trip also gives information on the directional distribution of the
site trips. This data suggests that of the total trips during the AM peak hour, 66% will be '
entering and 346A will be exiting: Conversely, during the PM peak hour, 40%will be entering
and W1*will be exiting. This is anticipated because more people would be arriving during the
AM peak hour than leaving. .The following table summarizes the anticipated trip generation for '

NeA the new site traffic needs to be applied to the adjacent roadway network. As a medical '
office building would draw site trips from the region, the applied trip distribution assumes that
25%of the total trips would be oriented to/from each the north,south,east and west.
Because exiting site traffic oriented to the north will be prohibited from turning left onto Sullivan '
Avenue, those trips have been assigned through the adjacent Colonial Centere where they are
anticipated to make a left-turn onto Route 30 eastbound. From there,these vehicles can make a
left turn onto Sullivan Avenue northbound at the signalized intersection. Although this traffic '
can utilize any of the four driveways serving Colonial Centere,they were all applied to the most
used driveway(identified as Driveway#2)to take a conservative approach to the analysis.
The proposed interconnection has the potential to alter traffic patterns to and from Colonial '
Po
Centere. It is not anticipated that exiting traffic will prefer to traverse through the medical
building development to turn right onto Route 194 (Sullivan Avenue) southbound. This is '
largely due to the fact the left-turns from the Colonial Centere driveways presently experience
minimal delay. Furthermore, the more conservative approach to this analysis will leave these
trips as left-turns from the un-signalized driveways rather than being reassigned as right-turns '
and processed through a signalized intersection.
Traffic ems_Colonial Centere from the east, south and west is also not anticipated to utilize '
the new driveway. Access from these directions is more convenient from Route 30 than by a
left-turn,from Sullivan Avenue. Entering traffic from the north,however, may elect to utilize the
