The corridor is about 7.6 km Cross-section – three lanes with centre lane reversible or four lanes and a median (Old Richmond Road and long. The purpose of the project was to provide adequate transportation capacity for existing and planned growth, to West Hunt Club Road) support the desired shift to sustainable and active transportation modes and to address safety issues along the corridor. Intersection traffic control – signals or roundabout Description of the Problem The road realignment between Hope Side Road and Old Richmond Road was screened out when the analysis showed The City of Ottawa Official Plan (OP) includes significant growth areas in Kanata and Stittsville and this growth will that it did not have a significant benefit to traffic overall but had significant impacts to approved development lands. The increase the number of trips into and out of the area, exacerbating the existing levels of congestion during peak periods. road realignment between Old Richmond Road and West Hunt Club Road was carried forward with consideration for Planned transit improvements will help to achieve the targets for transit use set in the 2013 Transportation Master Plan cross-section and intersection alternatives. (TMP) update but will not eliminate the need for road improvements. In addition to addressing travel demand, corridor improvements will provide an opportunity to introduce measures to address existing safety issues. For the evaluation of the three and four-lane alternatives (from Stonehaven Drive to Highway 416), it was noted that the footprint of the three-lane cross-section through Stony Swamp was less than the four-lane cross-section. While this Preferred Solution smaller footprint results in lower environmental effects, safety during operations was a significant concern. Without the benefit of an example in North America of a reversible lane of similar length and speed, a standard 4-lane roadway with a The alternative solutions generated to address identified needs were: narrow raised median was preferred. This decision was made with the knowledge that mitigation acceptable to the NCC would be a requirement for approvals. During detail design, potential methods to minimize the footprint will be Do nothing considered. Enhance Transportation Demand Management (TDM) Measures Implement Transportation Systems Management (TSM) Measures In accordance with City of Ottawa policies, roundabouts were investigated at each intersection location. At all locations, Expand the arterial road network roundabouts provided equal or superior levels of service for traffic. Roundabouts were carried forward for consideration Hope Side, Old Richmond and West Hunt Club Roads during detail design at study area intersections, with the exception of Moodie Drive and West Hunt Club Road where Fallowfield Road and connecting roads as needed traffic signals were preferred to minimize the impact on adjacent wetlands. The presence of traffic signals at the Highway Provide a combination of the above alternatives 416 southbound ramp terminal intersection means that there are two signals adjacent to each other. These signals will not interfere with the operation of the roundabouts elsewhere along the corridor. A combination of the identified alternative solutions was selected as the preferred solution. It is recognized that TDM and TSM measures will play an important role in the overall solution, as they do in the transportation
