My full response to the other points question is below. I found the survey slightly odd in that the questions where they asked for the most details were the least controversial sections. As soon as the lane became unidirectional you were left having to put everything in the general comments.
My main point is that narrow bi-directional lanes exclude families because of the limited ability to ride alongside an inexperienced slower child.
Reading the plans the kerb height on the vehicle side appears to be 10cm on the mound. Far from enough to protect cyclists on the inside of the bend especially if they are coming towards a large vehicle. They need to put airport specification anti vehicle bollards here.
Here is my response to the last quesiton. Sorry for the rather necessary repition, I felt it was required.
George IV Bridge: The cycleway here is too narrow for 2 way use. Either it needs to be unidirectional lanes or the lane needs to be 4m wide 1.5m each way does not allow sufficient space for overtaking or riding 2 abreast. It therefore excludes families. The only place a slightly narrower 3m lane would be acceptable would be on the bus stop bypasses. The lane will need to have 24 hour enforcement and/or bollard protection as drivers in Edinburgh are not to be trusted to keep out of it.
Bank Street: The cycleway here is too narrow for 2 way use. Either it needs to be unidirectional lanes or the lane needs to be 4m wide 1.5m each way does not allow sufficient space for overtaking or riding 2 abreast. It therefore excludes families. This is especially important on the steep stretches as riders are likely to be travelling slower leading to very high speed differentials. With the current setup most confident northbound riders will ignore the lane and traffic should be advised to expect bikes on the road. It may be better to reroute the uphill lane via St Giles street to allow space for uni-directional lanes down the mound or even closing bank street and taking affected traffic round via St Giles street if space is greater.
The Mound: The public/loading space is a poor idea. This will be dominated by loading and as such the project should be honest and call it loading space. Once again the cycleway here is too narrow for 2 way use. Either it needs to be unidirectional lanes or the lane needs to be 4m wide 1.5m each way does not allow sufficient space for overtaking or riding 2 abreast. It therefore excludes families. This is especially important on the steep stretches as riders are likely to be travelling slower leading to very high speed differentials. The bends on The Mound/Bank Street need more than a low kerb to protect them, especially when it a lane is on the inside of a bend. Substantial bollards will be required here to ensure large vehicles are not negligently turned over the lane. Cycles coming down the hill will often be doing 20mph and so any risk of meeting a vehicle here needs to be designed out from the start.
Princes Street/Hanover Street: When designing the crossing safe cycle crossing angles of the tracks need to be taken into consideration, especially if limited lateral movement space is being provided. It may be best to only provide short general traffic phases so that cyclists have plenty of time to cross without the risk of being bullied by drivers.
As on the other sections families are being excluded because the cycleway here is too narrow for 2 way use. Either it needs to be unidirectional lanes or the lane needs to be 4m wide 1.5m each way does not allow sufficient space for overtaking or riding 2 abreast. The cycle lanes here will need bollard protection to ensure delivery drivers do not abandon their vehicles in the cycle lane.
