Unsignalized Intersection Analyses The unsignalized intersection levels of service were estimated using the unsignalized intersection module of the Highway Capacity Software. For each intersection, a level of service grade is assigned to left turn movements iTom Cleveland Avenue, each movement iTom the minor streets, and overall minor street approaches. Table 21-5 presents the level of service results for the unsignalized intersections. With the exception of the North Centre Pointe Drive/Cleveland Avenue intersection, acceptable operations are expected at the unsignalized intersections. All movements at the Veritas Way, South Centre Pointe Drive, Lydia Avenue, and Brenner Avenue intersections with Cleveland Avenue are expected'to operate at LOS D or better in the p.m. peak hour under the three development scenanos. Level of service F is expected for the left turn ITom North Centre Point Drive to northbound Cleveland Avenue under all development scenarios. As a possible measure to improve this level of service, we evaluated whether the intersection would warrant traffic signal control. One of 11 warrants must be met for a traffic signal installation to occur. The peak hour warrant is met when the traffic volume of the high volume minor street approach (North Centre Pointe Drive) and the two-way approach volume on the major street (Cleveland Avenue) are greater than specified minimum volumes for one hour of the day. Traffic volumes are expected to be sufficient in the p.m. peak hour North Centre Pointe Drive intersection with Cleveland Avenue for the 2004 currently proposed development concept. Thus, under the peak hour traffic signal warrant, traffic signal control is expected to be warranted at the intersection in 2004 with the current Centre Pointe development concept. Although the North Centre Pointe Drive/Cleveland Avenue intersection is likely to experience level of service difficulties and meet traffic signal warrants in 2004, installation of traffic signal control at Lydia Avenue may be a preferre<1 alternative for two reasons. First, a signalized intersection at Lydia Avenue would better conform to County access spacing guidelines. Second, the potential for an east leg to the intersection at Lydia may exist. A broader benefit would be provided by a traffic signal on Cleveland Avenue that has the potential to serve both the east and west sides. Installation of a traffic signal at Lydia Avenue would improve the level of service at the North Centre Pointe intersection by creating gaps in the traffic stream on Cleveland Avenue and shifting left turning traffic ITom the unsignalized intersection to Lydia Avenue. Following completion of the Centre Pointe Business Park, traffic volumes should be monitored and traffic signal control considered when actual traffic volumes at Lydia Avenue and Cleveland Avenue meet warrants for traffic signal installation.
