or normalized change in inductance/frequency versus time) from any or all of the card channels on a
single graph.
5.2.5
All configuration and data acquisition software shall be provided with the required licenses,
documentation and training for independent Owner operation going forward.
5.2.6
Full disclosure of all serial protocols, message types and/or software parameters for the cards’
configuration & data acquisition functionalities shall be granted to the Owner, so that the Owner may
opt to develop fully functional card central management software for the Owner’s exclusive use.

Acceptance of Alternative Product
5.3.1
For any proposed product which does not appear on the Designated Sources of Materials (DSM)
listing for this contract item, the Contractor shall submit a Change Proposal for an alternative product
according to the requirements of the MTO General Conditions of Contract for Change Proposals,
under the category of “Alternative Types of Materials or Material Sources” subject to the following
additional requirements.
5.3.2
Alternative magnetic detector cards shall be subject to a successful evaluation period of minimum 4
months duration, during which the Contractor shall demonstrate to the Owner that the alternative
product meets all requirements of this specification. The Contractor shall provide and install three
alternative magnetic detector cards into controller cabinet 400CN0065DSR (existing magnetic
detector test site at Hwy 400 SB at Finch Avenue) for the purposes of this evaluation. Two-probe,
Owner supplied magnetic detectors (6-lane detector station 400DN0059DSS) shall be used to
evaluate the alternative cards. The Contractor shall provide 48 hours advance notice to the Contract
Administrator prior to commencement of this work.
5.3.3
The Contractor shall obtain, from the Owner, 6-lane detection data for a detector station employing
IDRIS® technology adjacent to 400DN0059DSS, and shall compute the difference in counts between
the 400DN0059DSS station and the IDRIS® station on a per lane basis, for each of the following
periods to be selected by the Contractor:
(i) a single 1-hour period of midday freeflow traffic for each month of the evaluation period.
(ii) a single 1-hour period of nighttime lightflow traffic for each month of the evaluation period
(iii) a single 2-hour AM peak period for each month of the evaluation period
5.3.4
The Contractor shall then be provided with 6-lane detection data from the Owner for another adjacent
detector station which utilizes DSM listed magnetic detector cards for the periods selected, and shall
compute the corresponding difference in counts between this station and the IDRIS® station.
5.3.5
At all times the Contractor shall ensure that the data from the three detector stations utilized in the
comparison is synchronized with respect to its timebase and the Contract Administrator shall verify
and certify all data and calculations.
5.3.6
The alternative magnetic detector card evaluation shall be deemed successful only if the count
difference between the 400DN0059DSS station and the IDRIS® station is smaller or equal in
magnitude to the count difference between the DSM listed magnetic detector count and the IDRIS®
station, for each of the 6 lanes and each of the periods listed above in 5.3.3.
