India, street design guidelines

india section

I recently came across a publication from India on urban street design. The document, called “Street design guidelines” is published by the Dehli Development Authority. The latest version published in 2010 is available from the webpage of the UTTIPEC (United traffic and transportation infrastructure (planning and engineering) centre) here.

The document describes “a set of 10 non-negotiable street design componentsas well as additional guidelines for world class streets”. The non-negotiable components are:

  1. components of the pedestrian only zone (includingkerb radii and slip roads)
  2. frontage zone or “dead width”
  3. universal accessibility features/ barrier free design
  4. multi-functional zone with planting for storm water management
  5. bicycle and non-motorized transport (nmt) infrastructure
  6. crossings
  7. medians, refuge islands
  8. street lighting
  9. urban utilities
  10. public aménities (toilets, bus stops, dustbins), hawker zones, signage

What I found particularly interesting:

  • The references for continuous networks for other than motorised transport. For example the document says “sidewalks and cycle lanes should be regarded as a transportation system which is connected and continuous, just like roadways and railways” (page 50) and “continuous and safe NMT lanes with adequate crossings are essential throughout the city” (page 75)
  • A road classification primarily based on speed and ROW (right-of-way width), with (e.g.) traffic lane widths suggested at minimum 3.3m for 70 km/hr
  • Discussion on the location of utilities
  • The 25 examples of road cross-sections

Some of the pages are a bit too cluttered, a simpler layout would make the information easier to absorb. Also, some of the graphics could be larger (and clearer)- for example the modified intersection design on page 48, and the graphic for a kerb-less street on page 119.

Nevertheless it is a document well worth looking through.

Urban street design seems to be a growing topic of interest in India, with the city of Pune planning to produce a street design manual (see here). Pune is in discussion with the UTTIPEC on the topic, as are also authorities in Mumbai and Hyderabad.
