N2  - India has a high incidence of fatalities in road accidents compared with other countries. The need for improvements in existing highways is outlined. Experience has shown that the following low-cost minor improvements could be highly effective: improvements in traffic control devices (signs, markings, delineators), minor physical alterations to the intersection layout, drainage improvements, provision of crash barriers and railings, improved access control, and improvements to median openings. Project types undertaken under minor enhancement objectives are described with reference to the situation in the UK and USA. Criteria for minor improvements are listed. The relationships between safety and key road features are considered. The planning and designing process for a minor improvement project is outlined. Common road safety issues requiring minor improvements are described: roadway improvements (horizontal alignment, vertical alignment, sight distance, cross-sectional elements, channelisers, medians and service roads, intersections, surface pavement), roadside improvements (crash barriers, fixed objects, bridges and culverts, relocation of access, drainage) and operational road improvements.<p />
