HIGHWAY NEEDS
TO Be BROADCAST
Addresses Will Be Given by
American Road-BuiIders'
Association.

Two radio talks advocating the ex-
nansion of highway programs will go on
the air on November "a and December
One talk was given November 10. These
talks have been arranged by the Amer
lean Road-Builders' Association. The
stations participating In this widespread
broadcast for the benefit of highways
cover the entire United States and
Hawaii.
On November "a 1.-THE Economy Of
Good Roads" will be discussed on the
air. "Road-Building for Unemployment
Relief" Is the subject Of the December
talk.
Three Safety Elements.
Three elements of safety are consid-
cred in the talk on highway safety-the
vehicle (now safe), the road becoming
safe), the individual mot thoroughly
controlledD. An appeal Is made to the
individual driver to use courtesy and
caution.
Highway activities are presented as
the biggest stock company in the world
for the public in the talk on the econ
omy Of good roads. Economy of roads
and streets Is brought about by reducing
losses. Economy is not merely mat
ter of reduced expenditures. On the
contrary, reduced expenditures means
increasing the losses under present con-
ditions of lack of safety and costly con-
geStion on the highways" state the
speakers.
Road building for unemployment re-
lief has been tested during the past
Summer" says the third talk, land, as
in previous tests, 1t has been found
most efficient in putting men to work
promptly. All types of men from indus
tries that are temporarily inactive are abb
sorbed readily in bodybuilding. More
than 100000 men were employed
directly on road-building during the
past Summer and 100000 other men
were kept busy furnishing supplies,
materials and equipment to road work.
ers."
Speakers include outstanding public
officials engaged in city, county and
State road and street activities.
Location Methods.
Location methods and equipment
have developed rapidly during recent
years, both in this country and abroad,
according to r. Getty Browning,
chairman Of the committee studying
highway location for the A. r. B. A.
Studies are being made Of aerial
surveying, giving an experience with
such survey, instruments for highway
surveying and methods and equipment
used on recent highway surveys.
Instrument makers in England.
France, Germany, Switzerland and
the United States are experimenting
with elaborate innovations.
Most engineers are extremely con-
sentative in the matter Of using meth
DDS other than those to which they
are accustomed and therefore installa-
ton Of new equipment has been diff
f1cult.
Aerial photography has been used
in the location Of highways for sew
eral years. Refinements in mapping
have recently resulted from greatly i'm
proved reproducing equipment. Topo-
graphical maps can now be made with
accuracy from aerial photographs,
often at less expense than by ground
methods
Used by United States Army.
The United States Army, a few
States and larger counties have made
use Of the quicker and, in many in
stances, more economical locating
methods.
This report, including information
on the utility of instruments of recent
design and aerial mapping, will be es-
pecially valuable to State, county and
city engineers.
