FORM 4 – New work item proposalVersion01/2015Scope of the proposed deliverable.

This standard specifies location requirements of Urban pedestrian bridge(footbridge) assemblies in cities. Pedestrian bridges outside of cities are not coveredby this standard. This International Standard is also intended to facilitate theunderstanding of installers of urban pedestrian bridges and municipalities.

Purpose and justification of the proposal*

The purpose of this international standard will be to:1) Provide characteristics for the installation of urban pedestrian bridges.
2) Facilitate the understanding of installers of urban pedestrian bridges.
Justification:
A pedestrian bridge, also called a footbridge, is simply a bridge, whether over landor water, that is designed for pedestrian traffic. Often, footbridges are constructedto provide pedestrians a safe way to cross from one side of a busy road to the otherwithout having to dash across, running the risk of being knocked down by speeding
vehicles. Footbridges also help to ease traffic.
Pedestrian bridges can be useful for linking buildings or popular destination s suchas shopping centres, large schools, recreational facilities, parking garages, and lightrail stations. Such bridges allow people in one building to access another building
across the street without having to go outside to cross the street. They are also
useful for linking areas separated by highways or freeways.
Locating pedestrian bridges must be based on criteria such as consideration ofimportant infrastructure, including: schools, universities, hospitals and crowded
places.
Locating pedestrian bridges should be based on the type of street to ensure the safe
passage of pedestrians. In choosing a location, the speed of vehicle traffic and otherissues related to urban development must be considered.
Pedestrian bridges should be located to serve pedestrians. This will ensure that theuse of any bridge is maximized. The natural topography should also be considered
in determining suitable locations for pedestrian bridges.
Factors to be considered range from traffic, physical, visual and landscape aspects
to economic, social and environmental as well.
Bridges should be accessible to all pedestrians and cyclists as well as mobility
impaired people who may require ramps.
Bridges can be prominent structures offering opportunities to create new landmarks
and to incorporate the cultural and historic values of the area into the design.
The importance of pedestrian bridges is the following:-Pedestrian Safety-Traffic reduction-Accident reduction-Protection of architecture of cities(Urban furniture)
The location of pedestrian bridges should consider characteristics such as:*The volume of pedestrian traffic*The volume of vehicle traffic*Distance vision of vehicle stop
*The time required for pedestrians to cross the street*Vehicle speeds*Distance from adjacent pedestrian crossings*Distance from adjacent intersections

Consider the following: Is there a verified mark et need for the proposal? What problem does
this standard solve? What value will the document bring to end-users? See Annex C of theISO/IEC Directives part 1 for more information.

A statement from the proposer as to how the proposed work may relate to or impact on
existing work, especially existing ISO and IEC deliverables. The proposer should
explain how the work differs from apparently similar work, or explain how duplicationand conflict will be minimized.
The proposed work will consider the important requirements of locating pedestrian

bridges for people’s safety. The safety of users must be considered in the bridge
location and design.
