On Japan’s tollways, this is often done with a single-purpose sign with a variable number, and different color of the numbers to indicate delay time. As Japan’s tollway system is really built up, there are a lot of variable and and matrix signs that I have not really seen in the US, (and I have no idea about Europe), so here’s some examples of signs I see every time on the tollway - these are from a small section of tollway coming out of Tokyo. so if we are going to have “variable” be a value, these are the kinds of signs that I would expect to find (and have =variable if quantitative data). - static motorway signs displaying variable information Upcoming traffic jams (between exit 4 and 1). https://www.google.com/maps/@35.978574,139.380073,3a,19y,181.36h,94.25t/data=!3m4!1e1!3m2!1s-lAuTWLqqcp3icYdDNdWkQ!2e0 <https://www.google.com/maps/@35.978574,139.380073,3a,19y,181.36h,94.25t/data=!3m4!1e1!3m2!1s-lAuTWLqqcp3icYdDNdWkQ!2e0> traffic on the Tokyo downtown expressways https://www.google.com/maps/@35.803439,139.53568,3a,55.7y,128.85h,99.19t/data=!3m4!1e1!3m2!1sjCYjDLHWm2WjvgAtmY-qeQ!2e0 <https://www.google.com/maps/@35.803439,139.53568,3a,55.7y,128.85h,99.19t/data=!3m4!1e1!3m2!1sjCYjDLHWm2WjvgAtmY-qeQ!2e0> Upcoming service area & parking areas status ( empty / busy / full ) https://www.google.com/maps/@35.958085,139.382156,3a,23.7y,327.77h,100.84t/data=!3m4!1e1!3m2!1sm6vOYbSACGMdcat0meaqQw!2e0 <https://www.google.com/maps/@35.958085,139.382156,3a,23.7y,327.77h,100.84t/data=!3m4!1e1!3m2!1sm6vOYbSACGMdcat0meaqQw!2e0> Travel time to the next exits: https://www.google.com/maps/@35.956195,139.383457,3a,55.4y,318.43h,104.41t/data=!3m4!1e1!3m2!1sImGDgsiePLYiDKhw0nlwiA!2e0 <https://www.google.com/maps/@35.956195,139.383457,3a,55.4y,318.43h,104.41t/data=!3m4!1e1!3m2!1sImGDgsiePLYiDKhw0nlwiA!2e0> #11 Maebashi: 40 minutes - green - so no delay.
