# Exhibit 10.1

# SETTLEMENT AGREEMENT, CONTRACT MODIFICATION
AND MUTUAL RELEASE

This Settlement Agreement,
Contract Modification and Mutual Release (the Agreement) is entered into by and between Econolite Control Products,
Inc. (Econolite) and Image Sensing Systems, Inc. (ISS). Econolite and ISS are referred to herein
collectively as the Parties.

WHEREAS, Econolite and ISS
have a contractual relationship memorialized in a series of written agreements; and,

WHEREAS, a dispute has arisen
between the Parties, and Econolite has filed an action which (after removal to federal court) is styled Econolite Control
Products, Inc. v. Image Sensing Systems, Inc., Case No. 05-997-JVS (RNBx) in the United States District Court for
the Central District of California (the Litigation); and,

WHEREAS, the Parties desire
to settle their dispute;

NOW THEREFORE, in
consideration of the mutual covenants and undertakings set forth below and other good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, Econolite and ISS agree as follows:

1.       ISS
will pay to Econolite the sum of Two Hundred Thousand Dollars ($200,000) within ten days of execution of this Agreement.

2.       ISS
will pay to Econolite the additional sum of One Hundred Seventy-Five Thousand Dollars ($175,000) if and when Econolite achieves
sales of Autoscope products of $33 million in calendar year 2006. Such additional payment shall be payable within ten days of the
day that Econolite provides ISS with a written notification that it has achieved $33 million in Autoscope sales in calendar year
2006.

3.       Paragraph 1
of the Modification to Manufacturing, Distributing and Technology License Agreement as of September 1, 2000 is modified as
follows: Beginning as of July 1, 2006, Econolite will calculate and pay royalties to ISS on Solo Pro products so as to split net
profit on sales of Solo Pro between Econolite and ISS 50/50. Net profit on sales is defined as sales price to the end
user less distribution commission (if any) and Solo Pro purchase price (calculated as has historically been done by the parties)
plus fifteen percent (15%) of purchase price for overhead:

As an example:

|(Hypothetical) Sale Price to End User                 |  |  | $ | 4,000  |  
|----------------------------------------------------- |  |  | - | ------ | -
|(Hypothetical) Distributor Commission (if applicable) |  |  |   | (800   | )
|                                                      |  | 
|Net to Econolite                                      |  |  |   | 3,200  |  
|Less Solo Pro Purchase Price (hypothetical)           |  |  |   | (1,000 | )
|Less 15% of Solo Pro Purchase Price                   |  |  |   | (150   | )
|                                                      |  | 
|Net Profit on Sales                                   |  |  |   | 2,050  |  
|ISS Royalty                                           |  |  |   | 1,025  |  
|Econolite Margin                                      |  |  |   | 1,025  |  

4.       The
royalty calculation in the preceding paragraph will apply to future generations of Solo Pro products (e.g., Terra) for the
remaining term of the Parties written agreement, unless there is a material change in the manufacturing process, in which
case the Parties will re-negotiate the royalty calculation in good faith with the objective of continuing a fair split of the
profits.

9.       The
Parties hereby acknowledge that there is a risk that, subsequent to the execution of this Agreement, they may discover, incur or
suffer from claims which were unknown or unanticipated at the time this Agreement was executed, including without limitation,
unknown or unanticipated claims which arise from, are based upon or are related to the issues and matters raised in the

and agree that this Agreement applies thereto. The Parties hereto expressly waive the benefits of Section 1542 of the California
Civil Code, which provides:

| | A general release does not extend to claims which the creditor
does not know or suspect to exist in his favor at the time of executing the release, which if known by him must have materially
affected his settlement with the debtor.
| | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The Parties hereto waive and relinquish all rights and benefits which they
have or may have under Section 1542 of the California Civil Code or the law of any other state or jurisdiction to the same or
similar effect to the full extent that they may lawfully waive an relinquish all rights and benefits pertaining to the subject
matter of this Agreement.

11.                 The
Parties each represent and warrant that no other persons or entities (other than their affiliates) have or have had any interest
in the claims, demands, obligations, or causes of action referred to in this Agreement. The Parties each further represent and
warrant to each other that they have not sold, assigned, transferred, pledged, conveyed, or otherwise disposed of any of the
claims, demands, obligations, or causes of action referred to in this Agreement. The person or persons who enter into and execute

12.                 The
Parties each expressly deny liability, and agree and acknowledge that this Agreement is a full and complete compromise of matters
involving disputed issues of fact and law, and that neither payment of any amounts, nor negotiation for or agreement to this
Agreement (including all statements, admissions, or communications or exchange of documents) by the Parties to this Litigation, or
their respective representatives, shall be considered admissions by the Parties. No past or present wrongdoing on the part of the
Parties shall be implied by such payment or by such negotiations.

13.                 The
Parties each expressly warrant and represent that before executing this Agreement they have received independent legal advice from
attorneys of their choice with respect to the advisability of making the above Agreement, or have had full and fair opportunity to
do so, that they have fully informed themselves of its terms, contents, conditions, and effect, and that they voluntarily agree to
the terms of this Agreement. The Parties agree that this instrument is executed as their voluntary act and deed. The Parties
acknowledge that they each may have sustained damages, expenses, and losses arising out of the matters released herein, which are
presently unknown or not suspected, and that such damages, expenses, and losses, if any, give rise to additional claims for
damages, expenses or losses in the future. Nevertheless, each of the Parties acknowledges that this Agreement has been negotiated
and agreed upon in light of this realization and, being fully aware of this situation, expressly releases and waives any and all
rights it may have to any damages or losses which are a result of the causes of action released herein, whether such damages are
now existing, known or unknown, or accrue in the future. This Agreement constitutes a complete compromise of all allegations
asserted in the Litigation, and the Parties fully assume the risk that the facts or the law may be otherwise than believed or
understood.

Agreement shall be binding upon and inure to the benefit of the representatives, successors, assigns, trustees, agents, attorneys,
and legal representatives of the Parties, as well as their officers, directors, employees, all present and former parents,
successors, subsidiaries, divisions, partners, and affiliated companies.

constitute one and the same Agreement. Facsimile copies of signatures on this Agreement shall be deemed valid and original.

16.                 This
Agreement contains the entire agreement between Econolite and ISS with regard to the matters set forth in it and may only be

contractual and not merely recitals. The mutual obligations and undertakings of the Parties expressly set forth in this Agreement
are the sole and only consideration for this Agreement, and no representations, promises, or inducements of any nature whatsoever
have been made by the Parties other than those expressly appearing in this Agreement. Each party and counsel for each party has
reviewed and revised this Agreement, and accordingly the rule of construction that any ambiguities are to be resolved against the
drafting party shall not be employed in the interpretation of this Agreement.

17.                 The
Parties agree that a waiver of any term or condition of this Agreement will not be deemed to be, and may not be construed as, a
waiver of any other term or condition hereof. The Parties agree that if any provision of this Agreement is adjudicated to be
