Abstract:

Road works zones are an integral part of the transport infrastructure. In Lithuania during 2014–2018. During the period, the number of vehicle registrations increased by 12%, which indicates that road infrastructure connections are growing (Skrodenis et al. 2020a). Many scientists refer to road work zones as sections with an increased probability of accidents, which distort normal driving conditions, and increase the time spent driving on these sections. In Lithuania during 2012–2019. During the period, 135 traffic accidents occurred in road work zones, where 3 people were killed and 33 were injured. Non-compliance with speed limits is considered by most scientists to be the most common cause of accidents. Speed monitoring studies carried out in Lithuania in the road works zones have shown that 78–88% of road users exceed the permissible driving speed. However, not all countries in the world (including Lithuania) pay sufficient attention to road work zones and the dangers lurking in them for both road users and road workers. The organization of traffic through road work zones can be carried out in various ways: by narrowing the lanes, but leaving the usual number of lanes, by organizing traffic in one lane with the help of traffic lights, and so on. When organizing traffic lights through road work zones, the phenomenon that large traffic jams occur in these sections is observed, which increases the travel time. Prolonged journey times mean that drivers do not follow the rules of the road and create dangerous situations for other road users, accidents occur. Time lag in road work zones is one of the major problems that forces drivers to behave irresponsibly and inadequately.
