Trip Distribution
3.1 Transportation and Traffic
Peak‐hour traffic counts conducted at the intersection of Larkin Road with Clay Pit SVRA access
road were used to identify the directional distribution of traffic. Sixty‐five percent of the traffic
generated by the site was observed to be heading north on Larkin Road, with 35% heading south
(Table 3.1‐7). This trip distribution is not projected to change significantly in the future and has
been used for this analysis. Table 3.1‐8 further defines the estimated regional distribution of
traffic generated by the site throughout the study area. The information in Table 3.1‐8 is derived
from observations at study area intersections. Using the identified directional distribution, traffic
volumes projected to be generated by the site were assigned to the study area street system.
Figures 3.1‐4 through 3.1‐5 display “project only” traffic volumes (i.e., only estimated traffic
volumes resulting from project implementation not including background traffic volumes)
assigned to intersections and roadway segments in the study area for existing, 2017, and 2030
planning horizons.
