The purpose of this memorandum is to summarize a supplemental traffic analysis for the
proposed Regents School Site to examine the impact of the by -right development, 23 single
family homes, at the proposed Regents School Site on Fontaine Avenue/Route 29 Southbound
Ramp intersection in the future year 2028 AM peak hour.
To accomplish the goal, this analysis obtained the 2028 no build AM peak hour traffic volumes
and traffic performance results from the prior Regents School Site Traffic Assessment
(10/12/2018), added in site trips generated by the by -right development, and analyzed the
2028 build AM peak hour traffic performance results with the 23 single family homes.
The following provides a brief summary of this information.
2028 No Build AM Peak Hour Traffic Volumes
2028 no build AM peak hour traffic volumes were obtained from the prior Regents School Site
Traffic Assessment (10/12/2018) and are illustrated in Figure 1 below.

2028 No Build AM Peak Hour Traffic Performance
2028 no build AM peak hour traffic performance results were obtained from the prior Regents
School Site Traffic Assessment (10/12/2018). The following Table 1 summarizes the analysis
results:

Trip Generation
The trip generation of the by -right development, 23 single family homes, was calculated using
web -based ITE Trip Generation Manual (10th edition) and is summarized in Table 2 below.

AM Site Trip Distribution and Assignment
AM Trip distribution was assumed as per the existing traffic pattern and is illustrated in Figure 2
below.

The AM site trips as summarized in Table 2 were assigned to the road network based on the
distribution as noted above. Figure 3 illustrates the AM site trips generated by the by -right
development, 23 single family homes.

2028 Build AM Peak Hour Traffic Volumes
The AM site trips as shown in Figure 3 were added to the 2028 no build AM peak hour traffic
volumes as shown in Figure 1 resulting the 2028 build AM peak hour traffic volumes. Figure 4
illustrates the 2028 build AM peak hour traffic volumes.

2028 Build AM Peak Hour Traffic Performance
2028 build AM peak hour traffic performance was analyzed in Synch ro/SimTraffic 9.2. It should
be noted that, the same as in the prior Regents School Site Traffic Assessment (10/12/2018)
and prior supplements, SimTraffic results were utilized for the level of service, delay, and queue
analyses. The following Table 3 summarizes the traffic performance results for 2028 build AM
peak hour.

Findings
Comparing the traffic performance results above for 2028 build AM peak hour to the traffic
performance results for 2028 no build AM peak hour, the impact of the site trips generated by
the by -right development, 23 single family homes, is minor on Fontaine Avenue/Route 29
Southbound Ramp intersection in the future year 2028 AM peak hour — the overall delay at the
intersection is 2.7 seconds longer, the delay on Fontaine Avenue is 0.1 second longer for both
eastbound and westbound, and the delay on Route 29 Southbound Ramp is 5.2 second longer.
