Samenvatting
A total of about 2000 drivers were observed in 16 crossings with driver head movements as the major dependent variable. This variable exhibits wide veriation between drivers as well as satisfactory inter-observer reliability. The results showed that many drivers turned their heads to look for trains in rail-highway crossings in spite of the fact that the crossings are equipped with flashing lights. Furthermore, fewer drivers turned their heads in directions, where the risk of train-vehicle collisions have been found to be very high, than in directions where the risk of accident is less high.
