To aid in the carrying on of its work, the Department operates a
Bureau of Criminal Identification and Statistics. The Bureau main-
tains fingerprint and photograph files and cooperates with the Federal
Bureau of Investigation and the police forces of other jurisdictions
in the exchange of information relating to the identification of of-
fenders or suspects. The General Assembly in 1941 authorized the
establishment of the Traffic Collision Statistical Bureau. This Bureau
receives reports of accidents from the various local police departments
throughout the State, tabulating and analyzing such reports and
preparing a monthly summary and analysis of all accidents which
is published in cooperation with the Maryland Traffic Safety Com-
mission. A Traffic Staff has been organized within the Department.
for the purpose of promoting traffic safety and traffic safety educa-
tional programs. The members of the staff speak before civic groups
and organizations and plan to build a library of motion pictures and
related visual aids to augment its work..

The Communication Bureau, established in 1935, provides radio
and teletype communication service with the various police barracks
throughout the State. It is a unit in a teletype network covering
fourteen States and the District of Columbia. The Bureau also pro-
vides radio communication service to the patrol boats of the Depart-
ment of Tidewater Fisheries. Through the Communication service
the latest weather forecasts are transmitted to the local barracks
for dispatch to County Agricultural Agents; such reports are also
transmitted to the District headquarters of the State Roads Commis-
sion. During 1947, the Bureau handled 236,000 teletype messages and
350,000 radio messages. The Department provides ambulance service
to rural areas as well as emergency service in the case of accidents.
It maintains ten ambulances throughout the State for this purpose.
A Training School is operated by the Department, at Fort Meade
for the purpose of training recruits for the State Police service. The
School is also available for the training of local peace officers. The
work of the Department is carried on through its local barracks
located throughout the State as follows:.
