M. T. ROUTES IN PERSIA
Volume I— Main Routes —1942
INTRODUCTION
1. This Volume has recently been amended and revised
largely on the basis of reports received since the entry of British
and Russian forces into Iran in August 1941. As a result of this
entry and the events which have followed it, it has been necessary
to enlarge the scope of the main routes, and these now include
all feasible roads from Iraq and the Persian Gulf to the Caucasian
frontier and Caspian Sea, and from India to North-east and
Central Iran. Many new minor routes have also been added.
When studying this Volume, it should be borne in mind
that the latest reports on which it is based are dated November
1941, and considerable improvements may since have been
effected.
2. Numbering of routes.
Main routes (Volume I) have been given Roman numerals
as before, and have been re-numbered in an anti-clockwise direc
tion, Minor routes (Volume II) are numbered in Arabic multiples
of the main routes, e.g.
Minor routes branching from, or in vicinity of, Route I
...1 to 19.
Minor routes branching from, or in vicinity of, Route V
...50 to 59.
Minor routes branching from, or in vicinity of. Route X
...100 to 109
and so on.
As far as possible the above principle has been observed,
but where there are more than nine minor routes branching from
or in the vicinity of a major route, e.g. Route VIII, it has not
been possible, and the next adjacent main route number has been
utilised, i.e. Route VII.
3. Classification of routes.
The following classifications have been observed throughout
this Volume :—
Capacity
Heavy M.T.
Two-way traffic A. 1.
(not less than 20 ').
One-way traffic B. 1.
with passings.
One-way traffic C. 1.
only very narrow.
The above classifications are necessarily arbitrary, and
routes vary constantly under the influence of new construction,
repairs, weather conditions etc., but they are a useful guide to
the general capacity of a route.
To take —
Light M.T. only. Horse Tpt only.
