6 This document has been reviewed and revised. The revised document is IRC:99 with title Guidelines for Traffic Calming Measures in Urban & Rural Areas . The task of revision of IRC:99 was assigned to Road Safety and Design Committee (H-7). The revised draft was prepared by the Subgroup comprising Dr. Geetam Tiwari, Shri Jacob George, Shri Marwah, Shri Kirori, and Mrs. Bina C. Balakrishnan. The draft was deliberated in a series of meetings. The H-7 Committee finally approved the draft document in its meeting held on 25th September, 2017 and decided to send the final draft to IRC for placing before the HSS Composition of H-7 Committee is as given below:Singh, ConvenorMarwah, Co-ConvenorGeorge, Member-SecretaryMembersAgarwal, Prof. (Dr.) , Prof. (Dr.) Sewa Agrawal, , Venkata Balakrishnan, Bina , S.

8 The valuable contribution made by Dr. Sanjay Wakchaure, SE MoRTH regarding review of detailed document deserves special Road categories and their specific designs are determined by considering the maximum permitted speeds of vehicles that will travel on them with convenience and safety. At certain locations like approaches to sharp curves, congested/accident-prone locations and residential streets, towards manned and unmanned level crossings, control of speed becomes necessary to promote orderly movement of traffic and to enhance safety. Traffic Calming techniques have emerged primarily as a society s requirement for safety. It is widely accepted that differences and variations in the speed, direction, and mass of vehicles are some of the key determinants of severity of road accidents. These techniques have played an important role in enhancing road safety by ensuring lower driving speeds and smaller speed differences between different road users.

9 Over the last 25 years, the residential areas in Europe have become much safer with the creation of 30 km/hr zones despite the considerable variation in the direction and mass of vehicles plying on them. Several such experiences from around the world have established that the use of Traffic Calming techniques to influence road design significantly reduces accidents, pollution and makes neighbourhoods more However, the case in India is quite different given the heterogeneity of modes of traffic on most roads (see Table ). The vehicles plying on urban roads, National Highways (NHs) and State Highways (SHs) vary widely in terms of operating characteristics. Sometimes tractors and animal carts share the carriageway with fast moving motorised traffic. The highways that pass through villages and towns are also shared with local traffic - resulting in wide variations in direction, speed and vehicle mass. Given the context of socio-economic conditions across the country, it is difficult to restrict access of non-motorised vehicles to highways.

10 The Traffic Calming techniques have to be adapted to the Indian context to achieve the goals of managing efficient traffic flow at the same time ensuring safety of all road users especially around areas where the Highways pass through the villages and Road construction and maintenance are expensive public expenditure items and the costs on the road users and overall society is also substantial. The social costs comprising of accidents involving injuries and deaths and pollution in the surrounding areas are difficult to quantify. In light of this, it becomes imperative to pursue policies that minimise transportation costs for the individual road links and the network as a whole using the limited financial resources efficiently. The extensiveness and diversity in road networks create opportunities to explore the wide range of traffic calming techniques and also consider trade-offs between one another to improve any In city and metropolitan regions, roads should be designed to restrict the passenger vehicles speeds at 50 km/h and those of trucks and commercial vehicles at 40 km/h.
