               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 of America 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 of America for complete financial statements. In the
opinion of management, all adjustments (consisting of normal recurring accruals)
considered necessary for a fair presentation have been included. Operating
results for the three-month period ended March 31, 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 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.

For the three-month period ended March 31, 2002, stock options would have had an
anti-dilutive effect on loss per share. Had net income been achieved, no common
share equivalents shares would have been included in the computation of loss per
share

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." No stock-based employee compensation cost is reflected in net income
(loss), 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 (loss) and net income (loss) 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".

The fair value of each 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.

Options to purchase 6,000 and 463,260 shares of common stock with a weighted
average exercise price of $7.50 and $3.24 were outstanding at March 31, 2003 and
2002, but were not included in the computation of diluted net earnings (loss)
per share because the exercise price exceeded the average market price of the
common shares during the period.


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




                                       8


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 their
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 in the circumstances.

Results of Operations (Comparison of Three-Month Periods Ended March 31, 2003
and 2002):

Revenues for the first quarter of 2003 were $1,556,000, which were down 3% from
$1,610,000 for the same period a year ago. The decrease is attributable
primarily to decreased product sales in Europe and Asia which were offset in
part by increased royalty income resulting from increased sales of Autoscope
products in the United States by Econolite. We do not believe the decrease in
international sales represents a downward trend, but we cannot be sure that the
war in Iraq or the severe acute respiratory syndrome (SARS) epidemic in Asia may
not have an adverse effect on sales revenue for the balance of fiscal 2003.

Gross profits were $1,299,000 in the first quarter of 2003, or 83% of revenue,
compared to $1,243,000, or 77% of revenue, for the same period a year ago. The
margin percentage increase was due to the mix of revenue with higher margin
royalty income increasing as a percentage of total revenue as compared to
product sales, which have a lower gross profit margin.

Operating expenses were $976,000 for the first quarter of 2003 compared to
$1,472,000 for the same period a year ago. The decrease is due to the
non-recurrence of severance payments and other restructuring costs totaling
$268,000 incurred in the first quarter of 2002, as well as continued cost
savings from the restructuring.

Research and development expenses were $183,000 in the first quarter of 2003
compared to $234,000 for the same period a year ago. The decrease is due to
fewer new product development projects in progress in the current quarter and a
smaller engineering staff compared to the same period a year ago. We do not
expect these expenses to change appreciably in subsequent quarters of 2003.

Other income, net was $3,000 in the first quarter of 2003, the same as for the
comparable period a year ago.





                                       9



Income tax expense for the first quarter of 2003 was $75,000. We expect to
eliminate our valuation allowance previously established to offset our net
operating loss and research and development tax credit carryforwards and thereby
incur less than the 34% statutory income tax rate for the remainder of fiscal
2003. No tax benefit from the loss incurred in the comparable period for the
prior year was derived as realization of the operating loss carryforward was not
reasonably assured. Accordingly, a valuation allowance was established in 2002
to fully offset the carryforwards.

Liquidity and Capital Resources:

Cash and cash equivalents increased by $318,000 for the first quarter of 2003
compared to a decrease in cash and cash equivalents of $361,000 for the same
period a year ago. In the first quarter of 2003, cash was provided primarily
from operating activities, offset in part by capital additions. For the same
period a year ago we had severance payment obligations of $268,000 and paid
$250,000 as an initial payment for the acquisition of the minority interest in
our subsidiary, Flow Traffic Ltd.

At March 31, 2003, we had $2,943,000 in cash and cash equivalents along with an
available revolving line of credit with a bank of $50,000, after giving effect
to letters of credit issued to the former minority shareholders of Flow Traffic.
On April 1, 2003, we paid $450,000 owed to the former shareholders of Flow
Traffic and cancelled the letters of credit, thereby increasing our available
line of credit to $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 foreseeable future.

Item 3. Controls and Procedures

         (a)      Evaluation of disclosure controls and procedures. Our chief
                  executive officer and chief financial officer, after
                  evaluating the effectiveness of our "disclosure controls and
                  procedures" (as defined in the Securities Exchange Act of 1934
                  Rules 13a-14(c) and 15d-14(c) as of a date (the "Evaluation
                  Date") within 90 days before the filing date of this quarterly
                  report, have concluded that as of the Evaluation Date, our
                  disclosure controls and procedures were adequate and designed
                  to ensure that material information relating to us and our
                  consolidated subsidiary would be made known to them by others
                  within those entities.

         (b)      Changes in internal controls. There were no significant
                  changes in our internal controls or to our knowledge, in other
                  factors that could significantly affect our disclosure
                  controls and procedures subsequent to the Evaluation Date.

         2. Based on my knowledge, this quarterly report does not contain any

         3. Based on my knowledge, the financial statements, and other financial

         4. The registrant's other certifying officers and I are responsible for

Exchange Act Rules 13a-14 and 15d-14) for the registrant and have:

                  a) designed such disclosure controls and procedures to ensure
         that material information relating to the registrant, including its
         consolidated subsidiaries, is made known to us by others within those
         entities, particularly during the period in which this quarterly report
         is being prepared;

                  b) evaluated the effectiveness of the registrant's disclosure
         controls and procedures as of a date within 90 days prior to the filing

based on our most recent evaluation, to the registrant's auditors and the audit
committee of registrant's board of directors (or persons performing the
equivalent functions):

                  a) all significant deficiencies in the design or operation of
         internal controls which could adversely affect the registrant's ability
         to record, process, summarize and report financial data and have
         identified for the registrant's auditors any material weaknesses in
         internal controls; and

                  b) any fraud, whether or not material, that involves
         management or other employees who have a significant role in the
         registrant's internal controls; and

         6. The registrant's other certifying officers and I have indicated in
this quarterly report whether or not there were significant changes in internal
controls or in other factors that could significantly affect internal controls
subsequent to the date of our most recent evaluation, including any corrective
actions with regard to significant deficiencies and material weaknesses.
