Kris,

You could extrapolate some of the site boundary requirements of HSE Guidance HSG151 "Protecting the public - your next move" as applying to both sides of a continuous protected walkway.
Where there is a risk of items falling then the same measures would apply as for a scaffold over a public footpath (i.e. a tunnel, lit if necessary).
Real problem is where the public pedestrian route is interrupted by a site vehicle traffic route - I don't think you could make that 100% secure, even with traffic lights, banksmen etc. Although there is an obvious "reasonably practicable" call when compared with (e.g.) new housing developments and streetworks, HSG151 (sensibly) says AVOID such crossing of traffic flows.

One suggestion would be not to bother with British Standards.

If its information on Construction sites your after look at the CDM Regs or if its a general workplace look at the Workplace (Health, Safety and Welfare) Regs. They both come with ACOP's at a fraction of the price. The regulations are the law. Comply with them and you will not be breaking any laws.

If your sites use boundary fencing to deter trespass and prevent access to hazards, then as the temp route will be part of that boundary it should meet the security requirements discussed in "Protecting the public..." etc. If it crosses site roads, then at night the temp route fencing will need to be extended across those roads [gates that close].

Alternatively, if your sites use localised secure fencing around specific work plots or hazards then the fencing for the temp route can be a lower standard, I would suggest looking at the standards for temp pedestrian routes at roadworks [see DfT CoP "Safety at Street works and road works" on the DfT website].

Don't forget the need to consider the disabled and the partially sighted. I would suggest that lighting is at least to the same standard as on the permanent route it replaces.
