This highway has speed limits ranging from100km/h to 80km/h and I had general concerns particularly coming up to a bridge were the road narrows and the shoulder disappears.
You may think the parents are doing a good job here of educating their children about riding on marked shoulders on 'high speed high volume' roads as a good thing. Depending on there destination there is no excuse for children riding on these type of roads. There is generally a safer solution than riding on cycle lanes with children, either on their own bikes or in child carrying seats.
ACT roads have commissioned a Pedestrian and Cycle Design course for engineers, designers and planners recently which they say 'provides a comprehensive coverage of basic engineering treatments for cycling and pedestrian provision'.
It the ACT there is no cycle proficiency tests for school students particularly for the last year of primary school and as the majority of cycle lanes are on 'high speed high volume roads' this is a concern for the well being of children, one the the ACT government doesn't fully understand.
Cycle lanes are good on low volume low speed environments that provide designated areas for cyclists on existing roads and are also used by school students in other countries.
There are cycle lanes on low speed low volume roads in Canberra in the 'mish mash' planned town of Gungahlin. Though some of these lanes look like an afterthought when they could have built good quality cycle infrastructure from the start.
Though both of these roads are at 60km/h and wouldn't give many parents the confidence to let their children ride on these roads to school. maybe secondary children could use these roads safely if they had the cycle proficiency training. A Separated cycle path could easily have been fitted given the width of the road median and natural strips. Many students would like to ride together and this type of infrastructure doesn't allow for that unlike in other places.........
