Regional engineers believed that a roll curb would serve as sufficient separation from traffic, and the BIA was against bollards (plus there really isn't room).
I do agree with you however, this is something that should have been foreseeable. I definitely raised it at all of the PICs that we had on this subject, but as a non-expert, the engineers, who should know better, are the ones who make the decision.
It is unfortunate that the design must now be retrofitted, with what is in my opinion, still a substandard design using flex bollards.
However, it's worth noting, that the regional engineers, actually see flex bollards as the "best" solution, preferable to barrier curbs, as they are recommending this for the entirety of the project...in theory if they had identified vehicle incursions as a problem with roll curbs at the beginning of the project, we'd still have ended up here...
