These images were not reproduced in the report and thus cannot be included here. The direction and width of streets depend on the claims of the traffic to be accommodated. Traffic must everywhere and in every direction find a clear view and an unimpeded path.
All intermediate widths depend on the circumstances of each case.
The gradients of streets should be as flat as possible. In level districts gradients of more than 1 in 70 should be avoided as far as may be, because they interfere with the asphalting of the road surface. In hilly districts gradients up to 1 in 20 are permissible in the case of main thoroughfares, and up to 1 in 10 in the case of side-streets. Where steeper inclines have to be dealt with stairs or footways should be provided. The latter should be employed more frequently than is at present the case on mountain slopes and for diagonal crossings of long blocks.
