A research project investigating the role of road markings in ...
A research project investigating the role of road markings in

reducing congestion and improving vehicle safety at motorway

junctions has been launched by the Highways Agency.

The initial phase of research will study the response of drivers to

chevron markings at motorway junctions. The study will investigate

whether there is a link between the length and width of chevron road

markings and how frequently motorists overstep them. The results will

be used to provide better advice to road designers to form part of

new safety standards.

The consultants carrying out the research would like to hear from

local authorities, other consultants and practitioners who are

carrying out similar research, or interested parties who have views

on the subject.

The research is being carried out because, as the number of vehicles

on our motorways increases, it becomes more important to regulate the

movement of traffic at junctions for the safety of drivers and the

smooth flow of traffic. Areas of chevron road markings in the form of

'noses' and 'ghost islands' are used to separate lanes of traffic

flowing in the same direction, and a variety of lengths and widths of

these chevron road-marking areas is used across the country to suit

local conditions.

Gordon Heath, the Highways Agency's senior technical adviser for

safety, said:

'We are looking for views on where specific problems are occurring at

motorway junctions on the network, such as where vehicles are

crossing solid white line road markings into chevron areas. We would

also like to hear about locations where the operation of a motorway

merge or diverge is perceived as being very good with few or no


'We hope the results of this project will enable us to optimise the

impact of road markings at motorway junctions and improve both the

safety of drivers and the flow of traffic.'


1. The research is being carried out by Atkins Highways and

Transportation on behalf of the Highways Agency. Anyone wishing to

2. The Highways Agency is an executive agency of the Department for

Transport, which manages, maintains and improves the network of trunk

roads and motorways in England on behalf of the secretary of state.

It works closely with other transport operators and with local

authorities to integrate the trunk road network with the rest of

England's roads and other forms of transport. More information is
