Here is the map I am proposing for Kanata and Stittsville:
Thick lines are more frequent routes (Transitway and major routes) and thinner lines are less frequent.
Route 93 - Orange
Route 96 - Green
Route 118 - Red
Route 161 - Pink
Route 162 - Maroon
Route 164 - Purple
Route 166 - Yellow
Route 168 - Blue
Service hours and notes:
93 - Full service, 7 days a week, every 10-20 minutes during peak periods, 15 minutes midday, 30 minutes evenings and weekends
96 - Full service, 7 days a week, every 5-10 minutes during peak periods, every 15 minutes midday (every 30 minutes on each loop direction), every 15 minutes to Tanger evenings and weekends (30 minutes to Stittsville clockwise only), every 30 minutes late evenings; some peak period trips end at Terry Fox
118 - Full service, 7 days a week, every 10-15 minutes during peak periods, every 15 minutes most other times
161 - Full service, 7 days a week, every 30 minutes during most time periods (every 60 minutes late evenings)
162 - Peak periods only, every 30 minutes (AM northbound and PM southbound)
164 - Limited service, 7 days a week, every 30 minutes peak period/counter-peak direction, 60 minutes during most time periods, no peak period/peak direction service or weekend evening service
166 - Limited service, 7 days a week, every 30 minutes during peak periods, every 60 minutes other times, no weekend evening service
168 - Full service, 7 days a week, every 30 minutes during most time periods (every 60 minutes late evenings)
The 164 and 166 would largely interline each other (peak period service could use buses otherwise deadheading), although the 161 and 168 wouldn't be able to interline with anything. The 168 along Campeau West and the 162 and 166 routings in the Fernbank area are as roads permit (also I think the 96 would have to use Huntmar to Hazeldean until Maple Grove connects to Stittsville Main, ultimately if Stittsville Main is extended to Palladium/Campeau then the 96 should follow that route with the 118 along Huntmar). The 196 would be eliminated immediately, the 188 would be eliminated once the 168 is extended.
In terms of cost:
93 - Increased cost for downtown extension and more frequent midday service, somewhat offset by shortening peak direction and late evening trips to end at Eagleson
96 - Basically neutral, the only thing changing is that the 96C branch and Castlefrank/Hazeldean service is eliminated (covered by the 118 and 161); the funding used for the 196 would be used here as well evenings and weekends
118 - Basically neutral, no doubling back along Katimavik, instead along Hazeldean and Huntmar
161 (combining 161 and current 164) - Decreased cost due to shorter, consistent route, although the loop is a bit longer than the current 164 loop in Bridlewood to maximize coverage
162 - Basically the same as the current 164 Hope Side branch, so neutral
164/166 (interlined) - New costs introduced as these are essentially new services, some of it offset by the decrease in the cost of operating the 161
168 - Basically neutral after Campeau West opens, decreased until then, southern part of the loop is removed (along Katimavik)
