June 2005 to December 2005
Central Road Research Institute, New Delhi (R)


Present Status and Progress


Scope and Objectives
The primary objective was to ensure that the stretch operates as safely as possible. The key objectives were to:

• Minimize the risk of severity of crashes on the NHs/Expressways;

• Minimise the risk of crashes on adjacent roads as a result of operation and maintenance of NHs/Expressways;

• Recognize the importance of safety in highway design to meet the needs and perceptions of all types of road users and to achieve a balanced safety solution

• Improve the level of awareness of safe design practices by all involved in the planning, design, construction, maintenance and operation of Indian roads.
Study Area
The route comprised 748 km length from 42.8 km of NH-8 (south of Gurgaon) and passes through states of Haryana and Rajasthan via NH-8, NH-79-A, NH-79 and NH-76 to the border of Gujarat with Rajasthan on NH-8. The route comprised 12 sections.
The upgrading of the Western Transport Corridor – Package A which has occurred over recent years has resulted in a substantial improvement in the engineering standards of the infrastructure and a corresponding lift in standards of safety. Nevertheless, there are a number of key areas for which the potential for further safety gains is substantial, particularly by the application of contemporary best practice.

There are many site-specific recommendations in the twelve reports pertaining to each section of the route, in addition to recommendations regarding standards and guidelines. It is felt that implementation of following actions will have the greatest impact on safety of the package A :

• Flattening of side slopes of fill embankments so that they are traversable in the event that a vehicle runs off the road.

• For new projects or when upgrading National Highways to dual carriageways the standards for shoulders be a fully paved width of 3 m

• Upgrading delineation along the route by installation of edge lines adjacent to the median (where not already provided, retro-reflective studs of lane lines, guide posts with reflectors, reflectors on crash barriers and tactile edge lines on the left of the carriageway; and

• Moderating vehicle speeds in urban areas and habitations by the implementation of a package of traffic calming measures.
