    It looks a bit like this: thats why they are usually on the road first thing in the morning.

    It means that a topographical survey is being done on the road i.e. the road is being mapped in detail.

    The "slow moving" bit refers to the fact that the survey crew moves along the road at a slow place, as opposed to normal road works which are generally in a fixed location.

    Google Earth & Street View = the Road Engineer's best friends ;)

    Google Earth isn't accurate enough for road design (a topo survey on a road using a total station (the yoke in the photo above) typically has an accuracy of 5mm).

    Also, Google Earth uses a different coordinate system to Ordinance Survey maps.

    There is two chaps walking along the road with a couple of poles with plastic mushrooms on top.
    I assume they have triggers and every time the plant the pole in the exact centre of the white line they pull the trigger.
    This probably stores or transmits the data to the truck following and allows accurate positional data for mapping.
    They have a vehicle about 400m back, then 200m and then the truck which follows the two lads with poles.

    I passed one of these slow moving surveys on the N4 twice last week - somewhere around Ballinafid and Rathowen.

    I did notice kilometers of orange cables at the side of the road and on two occassions three large trucks passed on the other side of the road doing maybe 50km/h. These trucks seemed purpose built for whatever task they were doing. I've no idea what was being surveyed.
