A map of the subject area is appended as Attachment 1. 5.4 Collision History In the past five years, there have been no reported collisions at the intersection of Stevenson Road North and Fairglen Avenue. 5.5 All-way Stop Control Study at Stevenson Road North and Fairglen Avenue Staff completed an all-way stop control study at the intersection of Stevenson Road North and Fairglen Avenue in May 2018. 5.5.1 All-way Stop Control Study - Safety Warrant The Ontario Traffic Manual (O.T.M.) and Transportation Association of Canada Geometric Design for Canadian Roads govern the use of all-way stop control. The all-way stop control warrant is based on collision history, traffic volumes and sightlines. Operating speeds are not part of the technical warrant criteria as prescribed by the manuals. 4
Meeting Date: May 31, 2018 Page 3 The O.T.M. specifically states stop signs are not intended to be used as speed control devices. The O.T.M. is a well-respected manual in the road engineering community and is accepted by the courts as a best practice. Failure to follow the criteria outlined in the O.T.M. places municipalities at significant risk. The manual includes warrants for the use of all-way stop control which state that all-way stop control should be considered under one or more of the following situations: As an interim measure, where traffic control signals are warranted but cannot be implemented immediately this is not applicable in this situation. As a means of providing a transition period to accustom drivers to a change in intersection right-of-way control from one direction to another - this is not applicable in this situation. At locations having a high collision frequency where less restrictive measures have been tried and found inadequate. The manual defines this as an average of four collisions per year, of type considered preventable by all-way stop control, over a three-year period. o During a three-year period there have been no reported collisions at the intersection of Stevenson Road North and Fairglen Avenue. This represents an average of zero collisions/year over a three-year period and this warrant is 0% satisfied. 5.5.2 All-way Stop Control Study Volume Warrant The O.T.M. states that all-way stop control may be considered on local roads if the following two conditions are met regarding minimum traffic volumes. A total volume on all intersection approaches exceeds 350 vehicles for the highest hour recorded. o In May 2018, traffic counts indicate that the highest hour recorded had 228 vehicles. If the volume split does not exceed 65/35 at a four-leg intersection, then all-way stop control may be considered. o In May 2018, the volume split was 93/7. This signifies that 93% of the total 24-hour volume collected are vehicles travelling on Stevenson Road North. Therefore, based on these two conditions, the overall volume warrant is not satisfied. 5.6 Sightline Review Staff have reviewed the sightlines at the intersection of Stevenson Road North and Fairglen Avenue in May 2018. Field investigations revealed no sightline deficiencies at this intersection. 5
