hello, TMP!
i do think that there should be traffic lights placed at the entrance and/or exit of the service centre in Duisburg to bring in some orderliness since all it has been so far is chaos. i think if the add-on team is able to put together something, it can go a long way in bringing some law and order. This will also make it easy to spot the perpetrators.
Now, more emphasis put on those on the main road will be very good as there is almost always vehicular traffic on there as compared to that of those in the centre. Therefore longer go-time (green lights) for those there will be good and will ease up traffic on the main road for those coming from the centre. I wouldn't talk much, but i do hope this budding idea is taken critical look as it will go a long way in clearing up the roads cleanly. i know the add-on team will figure something out. ?
Thank you.
