access roads. Adequate space need to be provided for children to walk to schools, for
parents to walk to their work places, etc.
Thus for access roads:
Dual 2-lane carriageway 7.30 m
¼ 7.30 m
Footways with drains underneath 2 Â 3.50 m ¼ 7.00 m
Total length of carriageway
14.30 m
This is approximated to 15 m with footways of 3.85 m wide on either side of the
road. Furthermore, an allowance of about 7 m is left on either side of the road
between the buildings and the road so that footways may be extended if needed. On
either side of the footways, flower shrubs will be planted for aesthetic reasons.
The secondary access roads are those that allow movement between two adjacent
access roads. Initially, it was proposed to add bicycle tracks, but it was thought better
to use the carriageway detailed above for bicycles and then restrict the movement of
motor vehicles.
That is, the movement of motor vehicles can be controlled using obstacles or
barriers thus limiting access at certain periods of the day.
A road link will provide access to the buildings from the access roads and vice
versa. Its major role will be to act as a walking path for the inhabitants. But it will
also be used in cases of emergencies to provide access to fire engines, ambulances
and taxis. Because of the rare occurrence of these events, the road will be a one way
single lane carriageway of 3.5 m width with footways of equal widths on each side of
the carriageway.
Fire hydrants will be provided at 150 m intervals along sides of the road or at the
junction of two roads whereby the maximum distance between the junction and the
buildings does not exceed 200 m since it is the length of the hose of a fire fighter.
3.4.3.4 Fly-Over Bridges for Pedestrians
Fly-over bridges need to be provided for pedestrians for crossing the wide collector
roads and also the access roads whereby there is frequent bus movement. This is to
reduce the risk of accidents. These bridges can be converted into green space areas.
(See an example on Fig. 3.12).
The sizes of bridge provided are to be the same as the footways along the roads
being crossed, that is,
Across a collector road:
Width ¼ 3.00 m or more, Length ¼ 24.00 m
Across an access road:
Width ¼ 3.50 m or more, Length ¼ 7.30 m
