CONSENT CALENDAR
DATE: June 13, 1995
SUBJECT: VIDEO DETECTION SYSTEM
DEPARTMENT: Community Development
BACKGROUND
Citanage Approval
Item to be presented by:
Anthony J. Nisich,�
Most of the City's major roadway intersections have sensors (inductive loop detectors), in the
pavement connected to the traffic signal controller that sense when vehicles are present. A new
type of sensor has been developed that does not require installation in the pavement. It uses
video cameras placed on the street light mast arms to sense the presence of vehicles.
The City has an opportunity to use this new device at two major intersections in the ongoing
Overlay Road Resurfacing Project along Soledad Canyon Road from Langside to Sierra Highway.
As part of this project, most of the existing road sensors will need to be replaced after the road
is repaved. Instead of re -installing the old style road imbedded sensor, staff proposes to use this
Video Vehicle Detection System at two major intersections within the project limits, which are
Soledad Canyon Road/Whites Canyon Road and Soledad Canyon Road/Sierra Highway.
Currently, the only supplier of Vehicle Video Detection Systems, the AUTOSCOPET"', is
Econolite Control Products, Inc. They are the sole manufacturer and distributor of this device.
The Autoscope has been installed at hundreds of sites worldwide, including the Southern
California cities of Lancaster, Bakersfield, Fontana, Fresno, Irvine, and Long Beach.
Staff performed a 20 -year life cycle cost economic analysis to compare the cost of using loops or
AUTOSCOPETM system as shown in Exhibit "A". This analysis shows that for major
intersections similar in size as Soledad Canyon Road/Whites Canyon Road or Soledad Canyon
Road/Sierra Highway, there is a substantial long-term cost savings in using AUTOSCOPE TM,
In the 20 -year period, this system will save the City approximately $30,000 per intersection,
which will virtually pay for the cost of the system itself. In addition to this direct cost savings,
there are indirect cost savings to motorists and the environment as a result of reduced vehicular
delay and emissions, because the system can maintain detection even during roadway
construction.

The following is a short list of other benefits and features for using AUTOSCOPE:
1. It is a very practical device to use in a growing community such as the City of Santa
Clarita, where due to the rapid growth, signalized intersections are often expanded or
modified to add traffic lanes which require additional road sensors.
2. Because it is a wireless detection, it requires very little maintenance.
3. It emulates all of the functions of an inductive loop detector, including bicycle detection.
4. It is non-destructive to the road structure.
5. It provides many features, such as the ability to obtain information on traffic counts,
vehicle classification, speed, flow rates, and level of service, all of which can be used for
planning and operational purposes..
6: Detectors are easily adjusted, moved or resized to meet changing traffic operating
conditions.
7. It can identify abrupt changes in traffic flow caused by stalled vehicles or slow moving
vehicles because of accidents, road detours, road closures and other incidents. With proper
communication equipment, it can automatically send this information as an alarm to City
Hall for City staff to make an appropriate corrective measure.
8. Promotes safety and reduced City liability because no workers would have to be in the
street to install or adjust it.
9. It is able to transmit live motion video of the intersection via various communication
systems for monitoring purposes.
Attached is a copy of the letter proposal by Econolite (Exhibit `B") which indicates a costof
$32,775.00 for each location, for a total amount of $65,550.00..
Funding for this project is available in Account No. 02-5400-227.
RECOMMENDATION
1, To waive the bidding process, as Econolite is the sole manufacturer and distributor of this
product.
Award a contract to Econolite to furnish and set up the AUTOSCOPE Video Detection
System for the intersections of Soledad Canyon Road/Whites Canyon Road and Soledad
Canyon Road/Sierra Highway for $65,550, and authorize a $4,450 contingency expenditure
should any change orders to the contract become necessary. The funds for this expenditure
are available in Account No. 02-5400-227. Authorize the City Manager or his designee, to
approve any and all other documents relating to this contract.

Please find referenced herein the requested proposal, ( ie., Overlay Road Resurfacing Project)
providing vehicle image sensor detection at the two specified locations; (a) Sierra
Highway/Soledad Canyon Rd.; (b) Whites CanyonlSoledad Canyon Rd. Some of the issues that
were noted at the intersections are listed below:
The overlay project would necessitate a costly installation of over 50 vehicle, loop
detections, per intersection to be imbedded into the roadway- Inductive loop failures
typically occur every three to four years.
Disruption to vehicle traffic due to lane or road closure causing increased costs
associated with traffic safety; signs, and liability during the construction phase.
-- Effects of increased environmental pollution caused by such delays.,
- Time duration to install imbedded loop detectors are estimated at three to four days
per intersection.
Econohte Control Products, Inc., proposes a Vehicle Image Sensing Detection System that would
significantly benefit the City of Santa Clarita by providing vehicle video surveillance and
incident detection at a cost comparative with inductive loop detector stations: (See Figure A)
The proposed system consists' of a Autoscope 2004-V4 Control Unit with a four (4) camera
configuration which provides vehicle detection on all vehicle or bicycle lane approaches entering
the signalized intersection.
Camera placement would be located on the luminaire arm of the existing poles at each roadway
approach to the referenced intersection. Only Video Belden Cable 8281 and 110 volt power
cable connections are required for each camera installation in the field,
With the appropriate camera lenses to cover the targeted area for each multi -lane approach,
vehicle detection is provided by selectable software which resides in the Autoscope 2004. The
detector types include stop line, presence, directional presence, and speed trap detection which
report vehicle speed and classification based on length.

P.O. BOX 6150 • ANAHEIM; CA 92816-0150
Count stations are provided in real time and compute the average traffic perimeters over user
defined selectable time intervals for:
Volume
Occupancy
Vehicle Classification
Flow Rates
Headway
Speed
Each Autoscope provides in excess of 64 zones of detection for left turn, thru-put; right turn lane
approaches, and advances detection. The proposed system provides outstanding flexibility on
the part of the user as detectors can be placed anywhere in the camera field of view and can be
moved in minutes by authorized personnel. The detectors are tuned automatically by built-in
software and the operation can be verified visually at any time.. The Autoscope 2004 provides,
for automatic data collection, incident detection, and automatically displays video output for
incident detection.
Autoscope output levels are compatible with the NEMA TS1, NEMA TS2 Type 2, Type 170, and
Type 179 standards.
Once the cameras are mounted to the luminaire arm and the field coaxial/power cables are
installed,. the system detection set-up and initialization can be achieved in less than four hours
per intersection.
The proposed system configuration includes the following items:

A Supervisor Computer is provided to program detection for Autoscope. This supervisor
computer can be purchased now, or purchase can be deferred until the time your agency wants
to be fully self-sufficient at programming detection. If your agency elects to defer purchase of
a Supervisor Computer, we will bring a Supervisor Computer to the site to enable set-up of
detectors at the time of your Autoscope installation. If your agency elects to proceed with
purchase of the Supervisor Computer, the price for the Supervisor Computer, including training
for its use, is as follows and is a one time non-recurring price.

The referenced price includes the Econolite Autoscope field set-up/turn- on and does not include
the labor associated with the mounting of the cameras, pulling field wire (ie., coax/power cables)
nor the cabinet wiring.
The significant benefit of our proposal is that it delivers video surveillance and automated
incident detection at a cost competitive with inductive loop detector stations. Further, our
proposed system can be installed without disrupting roadway traffic.
If there are any questions regarding the aforementioned, please do not hesitate to call.
