Traffic sign also fits - the travelling time to another place reflects the traffic density, and vehicle crashes are traffic warnings ..<br>

I think traffic_sign=variable_message is good for the feature you report.<br>

Similar to these pixel based Variable Message Signs, there are what is usually referred to as a Changeable Message Sign which has a fixed set of messages (2-4) where narrow sections will rotate to display a message, usually used for closing rural roads without power, a solar panel will drive the sections to rotate into place.</div><div><div><br></div><div>VMS are often used to display travel time messages so they do something useful until there is a higher priority message for motorists.<br></div><div><br></div>In the Intelligent Transport Systems (ITS) industry there are also a bunch of others specialised electronic signs, including Variable Speed Limit signs (dynamic speed with the option of a flashing annulus/red circle, used either pole mounted on either side of the road or on a gantry above lanes, also used in school zones), and Lane Use/Control Signals (displaying the permitted usage of a lane usually mounted above the lane, i.e. open, closed, or indicating you need to merge, on motorways especially with tidal flow/reversible lanes).</div></div><div dir="ltr"><div><br clear="all"><div><br></div>-- <br><div dir="ltr">Jono</div></div></div>
