During a weekday,traffic flows are typically highest during morning • <br /> (AM) and evening (PM)peak periods. Therefore, the potential for a project to adversely affect • <br /> the operation of a transportation system is greatest during these peak periods. The proposed • <br /> project would operate during both peak periods,therefore, this study focuses on potential <br /> impacts during both the AM and PM peak periods. • <br /> Study Intersections. Twelve study intersections were selected for analysis in the traffic study <br /> for the 2013 EIR,with input from County of San Joaquin staff. The study intersections and the <br /> type of control (signal or stop control) are listed in Table IV.13-3, below. The intersection • <br /> numbering corresponds to the locations of the intersections shown in Figure IV.13-1. • <br /> • <br /> • <br /> • <br /> • <br /> • <br /> • <br />
