New industrial and residential construction
requires the opening of new streets which must be
improved to allow access. The locations are in all
sections of the District. A tentative list of
locations cannot be furnished in advance because
exact locations of proposed construction is not
known.

Work under this project will be done either
by contract or force account, whichever is deemed to
be in the best interest of the District.

Traffic Control Facilities:

$565,000

The funds requested are to provide for the
design, engineering and installation of new traffic
control devices and the modernization of existing
controls. It is anticipated that approximately forty
new locations will be signalized during the 1972
Fiscal Year. The continually increasing volume of
traffic within the District of Columbia, the impact
of Freeway and Metro construction, and the changing
pattern of street usage due to Urban Redevelopment
requires that our program of design, installation
and provision for more traffic responsive controls
be continued. Such a system is needed to reduce
unnecessary delays, improve safety, provide for
special turning movements, provide for two signal
indications for each approach, and bring the entire
signal system into conformance with the provisions
of the Manual on Uniform Traffic Control Devices
for Streets and Highways,

It is necessary to continue the modernization
and replacement of the traffic control system equipment
now in service in order to regulate and change the

Agency Highways and Traffic

fixed time traffic signal sequences during peak hours
and emergencies. It is essential that this signal
improvement work be performed on a continuing basis in
order to utilized the full capacity of the existing
master controller.

Continuing studies are necessary in order to
program the long range conversion to a fully traffic
responsive signal control system. Such a system will
provide for maximum responsiveness to change in traffic
demands throughout the District of Columbia. An area
of approximately 200 intersections is under a special
study by the Federal Highway Admin, in cooperation
with the Department of Highways and Traffic for
developing a fully traffic responsive system using
computers.

The program of purchase and installation of
"blank-out" illuminated signs is to be continued,
These signs are installed at intersections where
certain turning movements are prohibited during rush
hours, where lanes or entire roadways are reversed
during peak periods and where specific traffic prob-
lems require automatically opening and closing traffic
lanes. These signs are illuminated during the hours
that the prohibition is in effect and must be
responsive to emergency traffic conditions such as
early dismissal of schools or Government personnel,
detours and special events. A number of these signs
have been installed to date and they have proven very
effective in promoting safe and efficient traffic
movement.

In addition, flashing signs with a more positive message, and operating only at the times when children

Page 23-CAP-7

are going to and from schools, are very effective in
alerting motorists approaching schools on arterial
streets of the legal speed limit. A program to connect
these flashers to the Master Radio Control System is
order to provide remote control operation, and to in-
stall these flashers at 20 additional locations along
major arterial routes adjacent to schools, will be
continued.

Sidewalk Replacement:
The funds requested are for the continuation of a
program initiated in Fiscal Year 1962. The intent of
this program is to replace deteriorated defective and
unsafe sidewalks in the District of Columbia. The side-
walks have deteriorated in recent years mainly due to
the effect of tree roots causing cracking and upheaval
of the pavement. At the start of this program, it was
estimated that approximately 15% of the existing side-
walk yardage was in need of replacement, and progress
has been made toward reducing this backlog. Our normal

The funds requested are to provide for the
construction and/or reconstruction of drainage structures
where no major street improvement is necessary.
This
work is chargeable to the Highway Fund since its pur-
pose is to provide proper drainage of surface water
from public space. The work consists of installation
of culverts, catch basins and connections.

The northwest area of the city bounded on the
north by New York Avenue, on the east by North Capitol
Street, on the west by Third Street, and on the south
by Massachusetts Avenue, has been designated as an
Urban Renewal Area. The main activities proposed for
this area will be residential redevelopment and re-
habilitation of existing housing for middle income
families, and public housing for low income families.

The redevelopment of this area will involve the
closing of some streets and alleys, the repaving of
others and the creation of new alleys and walkways.
The funds requested in Fiscal Year 1972 cover the costs
of the Department in this area. These costs are:
