> In Rio de Janeiro, there are lanes that change directions at certain times of day (e.g. after 5pm), and the only thing that indicates this is a static signboard.
We have this here in Phoenix, Arizona; our north-south running "7th Street" has this kind of changeover for morning and evening rush-hour traffic to move people in/out of the downtown area quickly during weekdays (Monday-Friday). All other times it is meant to be treated as a median (suicide lane) for making lefts.
I haven't heard of many accidents on it in the 20+ years I've lived here; there have been a few, though. Usually the problems arise near the changeover times; some people's clocks are slow or fast, or they are paying attention, etc. So head-on collisions can occur, but they seem to be fairly rare. There's also the possibility of those not paying attention and rear-ending someone using the lane to make a left turn (I believe this is still legal, in order to access businesses along the route).
Personally, I try to avoid that lane - it just seems like the perfect setup for a one-way trip to the morgue.
