SAFE HARBOR STATEMENT UNDER THE PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995

This Quarterly Report on Form 10-QSB contains forward-looking statements within
the meaning of Section 27A of the Securities Act of 1933, as amended, and
Section 21E of the Securities Exchange of 1934, as amended. Forward-looking
statements represent our expectations or beliefs concerning future events and
can be identified by the use of forward-looking words such as "believes," "may,"
"will," "should," "intends," "plans," "estimates," or "anticipates" or other
comparable terminology. Forward-looking statements are subject to risks and
uncertainties that may cause the Company's actual results to differ materially
from the results discussed in the forward-looking statements. Factors that might
cause such differences include, but are not limited to:

         o        lack of market acceptance of our products;

         o        budget constraints by governmental entities that purchase our
                  products;

         o        dependence on third parties for manufacturing and marketing
                  our products;

         o        continuing ability of our licensee to pay royalties owed;

         o        our inability to diversify our product offerings;

         o        revenue fluctuations caused by our dependence on sales to
                  governmental entities;

         o        failure to secure adequate protection for our intellectual
                  property rights;

         o        failure to respond to evolving industry standards and
                  technological changes;

         o        our inability to properly manage a growth in revenue and/or
                  production requirements;

         o        our inability to meet our future additional capital
                  requirements;

         o        our inability to retain key scientific and technical
                  personnel;

         o        control of our voting stock by insiders; and

         o        conditions beyond our control such as war, terrorist attacks,
                  severe acute respiratory syndrome (SARS) epidemic and economic
                  recession.


We caution that the forward-looking statements made in this report or in other
announcements made by the Company are further qualified by the factors set forth
in the Cautionary Statement included as Exhibit 99.1 to this Quarterly Report.

Note A:  Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been
prepared in accordance with accounting principles generally accepted in the
United States for interim financial information and with the instructions to
Form 10-QSB. Accordingly, they do not include all of the information and
footnotes required by accounting principles generally accepted in the United
States for complete financial statements. In the opinion of management, all
adjustments (consisting only of normal recurring accruals) considered necessary
for a fair presentation have been included. Operating results for the six-month
period ended June 30, 2003 are not necessarily indicative of the results that
may be expected for the year ending December 31, 2003. For further information,
refer to the consolidated financial statements and footnotes thereto for the
year ended December 31, 2002.

Certain reclassifications have been made in the 2002 condensed consolidated
financial statements to conform to the 2003 presentation.

Options to purchase 6,000 and 589,760 shares of common stock with a weighted
average exercise price of $7.50 and $2.63 per share were outstanding at June 30,
2003 and 2002, respectively, but were not included in the computation of diluted
net income per share because the exercise price exceeded the average market
price of the common shares during the period.

Note C: Stock Options

Stock options issued to employees are accounted for under the intrinsic value
method as prescribed by APB Opinion No. 25, "Accounting for Stock Issued to
Employees." Except for performance based stock options, no stock-based employee
compensation cost is reflected in net income, as all options granted had an
exercise price equal to the market value of the underlying common stock on the
date of grant. The following table illustrates the effect on net income and net
income per share if we had applied the fair value method of accounting for stock
options under the provisions of FASB Statement No. 123, "Accounting for
Stock-Based Compensation" using the assumptions described below (in thousands,
except per share information):

For purposes of the pro forma information the fair value of each stock option
granted is estimated on the date of grant using the Black-Scholes option-pricing
model with the following weighted-average assumptions used: zero dividend yield;
expected volatility of 136% in 2003 and in 2002; risk-free interest rate of
4.25% in 2003 and in 2002; and expected life of 10 years for all years
presented.

Item 2. Management's Discussion and Analysis of Financial Condition and Results
        of Operations

Overview:

We have developed proprietary machine vision technology that converts real world
information into digital electronic signals for processing by computer, and have
applied it to traffic management problems. Our technology uses standard video
and computer equipment, combined with proprietary technology, including complex
detection algorithms, computer software, special purpose hardware, and a
Microsoft Windows(R)-based graphical user interface that enables standard video
cameras to work with the Autoscope system. The majority of our revenue is
derived from royalties received from Econolite Control Products, Inc., our North
American and Latin American distribution partner, based on its sales of traffic
control products which use our technology. A secondary source of revenue comes
from direct sales, which are primarily to customers in Europe and Asia.

Our critical accounting policies, including the assumptions and judgments
underlying them, are disclosed in Management's Discussion and Analysis of
Financial Condition and Results of Operations in Form 10-KSB for the fiscal year
ended December 31, 2002. These policies have been consistently applied in all
material respects and address such matters as revenue recognition, goodwill and
income tax accounting. While the estimates and judgments associated with the
application of these policies may be affected by different assumptions or
conditions, we believe the estimates and judgments associated with the reported
amounts are appropriate under the circumstances.

Results of Operations (Comparison of Three-and Six-Month Periods Ended June 30,
2003 and 2002):

Revenues for the second quarter of 2003 were $2,597,000, up 16% from $2,236,000
for the same period a year ago. The increase in revenues for the second quarter
was due primarily to a 77% increase in product sales over the comparable period
in 2002, which was offset in part by a 3% decrease in royalty income compared to
the second quarter of 2002. The increase in sales revenue was due primarily to
large product orders shipped to customers in Korea, China and Europe in the
second quarter. The largest orders in both Asia and Europe were for products
introduced within the past year. Royalty income for the second quarter of 2003
failed to match the comparable period in 2002 because Econolite was not able to
duplicate the very large second quarter sale in 2002 for a massive road
construction project in the Denver, Colorado area.

Revenues for the six-month period ended June 30, 2003, were $4,153,000, an
increase of 8% from $3,846,000 a year ago. The increase in product sales in the
second quarter of 2003 was the primary reason for the increase. An increase in
royalty income from Econolite of 6% over the comparable six-month period in 2002
also contributed to the increase in revenues.

Gross profits for the second quarter of 2003 were $2,107,000, or 81% of revenue,
compared to $1,829,000, or 82% of revenue, for the same period a year ago. Gross
profits for the six-month period ended June 30, 2003 were $3,406,000, or 82% of
revenue, compared to $3,072,000 or 80% of revenue a year ago.  The slight


                                       9


decrease in gross profit margin for the second quarter was due primarily to
the decreased mix of higher margin royalty income as a percentage of total
revenue, which was offset in part by improved margins on product sales. These
margins increased to 61% from 52% for the comparable period in 2002, reflecting
higher margins on new products introduced in 2003. The margin increase for the
first half of 2003 over 2002 was due primarily to increased margins on product
sales from 52% to 58%. We do not expect that our cost of product sales relative
to product sales or royalty costs relative to royalty income will change
appreciably during the balance of 2003.

Operating expenses were $1,033,000 for the second quarter of 2003 compared to
$1,269,000 for the same period a year ago. The decrease is due primarily to the
non-recurrence of $206,000 in severance pay and other restructuring costs
incurred in the second quarter of 2002. For the first half of 2003, operating
costs were $2,009,000 compared to $2,741,000 for the first half of 2002. The
decrease was due primarily to severance and other restructuring costs totaling
$474,000 incurred in the first and second quarters of 2002, which did not recur
in 2003. Employment cost savings from the restructuring continue to contribute
to the decrease in operating expenses.

Research and development expenses were $162,000 in the second quarter of 2003
compared to $124,000 for the same period a year ago, while R & D expenses were
$345,000 for the six-month period ended June 30, 2003 compared to $358,000 for
the comparable period in 2002. The increase in the second quarter of 2003 over
the comparable period in 2002 was due primarily to increased activity in
developing communication protocols and other software upgrades. The slight
decrease for the first half of 2003 compared to 2002 resulted primarily from
fewer new product development projects and a smaller engineering staff in the
first quarter of 2003 compared to the same period a year ago.

Income taxes for the second quarter and first half of 2003 are not comparable to
the same periods in 2002 when the entire federal tax expense was offset by net
operating loss carryforwards. In 2003 we expect to recognize the remaining net
operating loss and research and development tax credit carryforwards, which will
reduce our income tax expense below the 35% statutory level. As of June 30,
2003, we have net operating loss carryforwards for income tax purposes of
$372,000 and research and development tax credits carryforwards of $321,000 that
expire in the years 2007 through 2020.


Liquidity and Capital Resources:

Cash and cash equivalents increased by $627,000 for the first half of 2003
compared to a decrease in cash and cash equivalents of $60,000 for the same
period a year ago. In the first half of 2003, cash was provided primarily from
operating activities, offset in part by payments to former shareholders of our
subsidiary, Flow Traffic Ltd. For the same period a year ago we had made a
$300,000 initial payment for the acquisition of the minority interest in Flow
Traffic Ltd.

At June 30, 2003, we had $3,252,000 in cash and cash equivalents along with an
available revolving line of credit with a bank of $500,000. Management believes
that our cash and investment position, anticipated cash flows from operations,
and funds available through our bank line of credit will be sufficient to meet
cash and working capital requirements for current operations for the forseeable
future.
