Compiling Iran's code for road markings on rural roads, carried out for the Road Ministry Research Institute in 2007. The project is listed under Rahyaft's road and highway engineering work, which runs from geometric design to upgrading existing roads. Drafting a marking code of this kind means setting national rules for the type, dimensions, colour and placement of lines and symbols on rural roads, so that markings are applied consistently across the network.
