Agency: Gouvernement du Québec, Ministère des Transports Date:
1981/11/30
M. Marc Robert (418) 643-6808
1. What are the future data-processing needs?
0
Accuracy of data? Has to be realisticRetrieval of data? In memory with a terminal Real time or batch? Batch
2. What is the present computer equipment?
CPU? IBM 360
Operating system? Main central computer Languages? FORTRAN
User ports? Deck tape and interface RJE?
Interactive ports? Cards What models of terminal?
Program and data input facilities?
9-track tape? x Density?
Floppy?
Density?
Cards? x
Any teleprocessing requirements? No If yes, what medium?
Protocols?
, Any existing software for application? Yes
Any data-base presently? We develop our dwn program to list data and extract data for curves and slopes. But we dont use it any . Notes: more, because datas are flot precise
enought for gedmetric surveys.

MEETING RE QUEBEC DOT
Present: W. Grundmann F.. Kellogg J. Wallis
Agenda:
Discuss Report & Correspondence Consider Complaints
Consider Requirements
•
4. Review Past History1. Report & Correspondence
Translations, completed by Sonia Daudet, discussed and complaints isolated principally to effects of vehicle movement on North seeking mechanism of Sperry Gyro and - HuMphrey Vertical Gyro.
0
2. Complaints(i ) Absolute Value of Direction flot accurate, however change in direction is good. TECHWEST claimed accuracy 1. 2 ° . Subsequent work shows accuracy during operation is approximately -1 50 . This variance is introduced due to acceleration and braking effects on North seaking mechanism of Sperry Gyroscope.

Meeting re Quebec DOT -2- November 4, 1981
Potential Remedy: Be aware of cause and effect and attempt to
"smooth" vehicle's operation. (It is noted horizontal curvature is satisfactory. This is due to very frequent data sampling rate and acceleration and braking effect being virtually eliminated.)
(ii) Transverse Slope Measurements Influencéd by Vehicle Movement.
This is acknowledged and referred to in the "Guide." See Section 8.5.11.
TECHWEST is investigating the use of ultra-sonic sensors on each corner of the vehicle to detect vehicle attitudes, and processing resultant data with on-board micro-processor.
If satisfactory, we will offer this as a retrofit. The
package will contain the 4 sensors, analogue circuitry, together with drive circuitry.
Price level estimated in the $10 - 15 K Range.

Comments as for transverse slope, again influence of acceleration and braking are discussed in "Guide to Interpretation of
Photolog Film and Systems Specifications." See Section 8.5.8.

Dear Sirs:
Re: Highway Photologginq
Early in 1982 TECHWEST ENTERPRISES LTD. will be offering two new micro-processor based photologging systems. Each will feature full alpha-numeric display with a data entry capability via a keyboard. Each system may be fitted to 16 or 35 mm optical and/or video cameras.
The design of the two systems is such that at a latter date it will be possible to expand an existing system 'A' to the more sophisticated 'B'.
This would entail certain minor modifications, as an example the camera image areas will have to be modified to accommodate two or three unes of data, however these modifications would be minimal.
With this letter introducing the new systems, we would respectfully request a response with an opinion of their potential attraction to your operation from an inhouse capability, or contract service, point of view. If the enclosed detail request form is of use, kindly ensure a phone number contact is noted for follow-up purposes.
Hoping to have an opportunity of discussing this extension to our technology with your office, and looking forward to continuing this correspondence in the very near future, we remain.
Yours truly,
TECHWEST ENTERPRISES LTD.
