As indicated, the signalized intersections all offer acceptable overall levels of service under the 2030
background conditions. However, individual approaches at the intersections of Highway 26 with
Harbour Street West/Balsam Street and High Street with First Street experience poor operating
conditions (LOS F).
The unsignalized intersections both experience a level of service F with long delays during the PM
peak hour. The eastbound movement at High Street and Third Street also experiences a level of
service F during the AM peak hour.
4.2.2 Recommended Intersection Improvements
The following intersection improvements are recommended to address the operational issues
associated with the 2030 background traffic volumes. The intersections were analysed given the
recommended improvements with the results provided in Table 14 whereas detailed worksheets are
provided in Appendix E.
Highway 26 & Harbour Street West/Balsam Street
The signalized intersection of Highway 26 with Harbour Street West/Balsam Street experiences overall
levels of service B and E during the 2020 AM and PM peak hours, respectively. The westbound and
northbound movements each experience a level of service F with delays of 154 and 81 seconds
respectively, during the PM peak hour. Given the volume of eastbound right turning vehicles (280
during the PM peak hour), an exclusive eastbound right turn lane is recommended to remove the right
turning traffic from the eastbound through traffic. It is also recommended that the signal timing plans
be revised to include a permitted and protected phase for the northbound left turn movement and a
coinciding permitted and overlap phase for the eastbound right turn.
As indicated in Table 14, the operations will improve to a level of service C and A for the westbound
and northbound movements respectively.
