TIMCON teamed up with R.J. Burnside to undertake a Municipal Class Environmental Assessment (EA) to investigate the proposed extension of Sheridan Park Drive in the southwestern area of Mississauga. TIMCON completed a Safety Performance Study to identify transportation safety impacts under existing and future conditions. This assessment examined both existing and future conditions with the recommended improvements. The findings pointed to higher than normal collisions at various intersections arising from poor operations due to inadequate layouts, lack of turning lanes and poor signal timings. Under future conditions, implementation of the proposed measures would result in positive safety impacts with reduced number of collisions.
