Fall
Start Time: 6:02 pm
​
End Time: 7:04 pm
​
Discussion
Full testing needs to start as documentation for the report is needed. Results from testing is highly suggested to be place in a graph format whenever possible. A format for the fail safe mode is clarified and agreed upon. The design success criteria and Engineering Specifications are needed updates for the website. Lastly, the report draft was critiqued with any necessary changes.
Meeting 21

Fall
Start Time: 6:04 pm
​
End Time: 6:33 pm
​
Discussion
Adjustments need to be made to the design flowchart in terms of the signaling as the red LED will always be on. More effort is needed as deadline of the design is drawing near. Debugging assistance was given for the queuing situation as a coding argument was suggested to help solve the problem. The next topic was the report as we collectively went over it making changes were need be.
Meeting 20
10/29/2021
Fall
Start Time: 6:06 pm
​
End Time: 6:52 pm
​
Discussion
Website updates were reviewed and corrections were needed to be made to the progress log. Updates from the small scale testing of the system were made and the results are leading a positive outcome but continued debugging is needed as a delay issue is not having the queue work fully as intended. Suggestions were made to help deal with this.
The pedestrian crossing aspect of the system was agreed on being timed based instead of tracking, the pedestrian diagram needs to be updated to reflect this.
The design draft report of chapter 1, 2, and 3 was presented and critiqued with needed changes as the design rubric was updated.
Meeting 19
10/22/2021
Fall
Start Time: 6:04 pm
​
End Time: 6:35 pm
​
Discussion
A max distance needs to be found as it relates to the Bluetooth communication and it can be a estimation. Preparation of a live testing will begin in the coming week, it was suggested to make the testing small scale as it would be easier to control. Due to time constraints the pedestrian crossing will be time based instead of using object detection to signal when the pedestrians has finish crossing. The goals for the next meeting will consist of updates on the small scale project testing and working on the design report.
Meeting 18
10/15/2021
Fall
Start Time: 6:05 pm
​
End Time: 6:45 pm
​
Discussion
Bluetooth was confirmed to be the preferred choice of transmission but some questions were brought up with its use like what is the max distance, what Bluetooth protocol is being used, and distance of a typical intersection. These questions were to be addressed in the design report. Professor Ejaz also asked about the security of Bluetooth and this was answered as it is a closed network that can only be connected if both parties verify and agree to the pairing.
The hardware of the main system was assembled and tested for the rate of power recharge and it was faster than expected. Some of the last additions that are to be made are around weatherproofing. Lastly on the topic of ventilation, the max temperature that a raspberry pi can perform under was questioned as the pi would begin to throttle itself and with extreme temperatures become defective through heat damage. A controller for temperature control that would handle the fans for ventilation can be what alleviates this issue.
Meeting 17

Fall
Start Time: 6:04 pm
​
End Time: 6:45 pm
​
Discussion
Quickly went over Kyle's contributions with the hardware of the project as he was coming back dealing with personal matters. Mark's contribution of the change in transmission system to MQTT was explored and possible issues were brought up. MQTT would need access to the internet and with this being constant it can bring in a additional financial charge with the inclusion of a hot spot router. The suggestion of Bluetooth was brought up as an alternate and would be more optimal as it would not be a recurring cost. The overall range would take a hit due Bluetooth having a shorter range but it shouldn't be an issue as this is a prototype.
Object detection was next as a topic as the day detection worked as intended but in low light it is not as stable. Lastly the way in which the queue would be tested with multiple incoming vehicles through OpenCV.

Fall
Start Time: 6:03 pm
​
End Time: 6:59 pm
​
Discussion
Not much was discussed as Kyle and Mark each had family troubles. Kyle was not able to make the meeting because of this. Mark brought his continued issues with the data transmission with the multiple transceivers. With continued trouble with the transmission it was decided to pause on the transmission and give focus on the object recognition and give some more time into another form of data forwarding.
Meeting 14
09/16/2021
Fall
Start Time: 6:03 pm
​
End Time: 6:59 pm
​
Discussion
The transmission code was mostly completed as the code was not switching between each transmitting and receiving module from the main pi. Continued conversation of the concern of false positives from the object recognition and how to possibly address it. Ideas of fail safes for night detection to combat false positives like once an object is detected then a red light would output at all crossings and possible timing out for vehicles if they sit at the intersection for to long. We must build scenarios that would be a possible figure out how to fix them.
Meeting 13

Fall
Start Time: 6:09 pm
​
End Time: 6:39 pm
​
Discussion
Both Mark and Kyle gave updates about their task for the week. The transmission is to be completed by next week. Kyle's power draining results were recorded. Concerns about the structural integrity of the enclosure was brought up as it had warped from the outside heat. An idea to modify a commercial enclosure was brought up as a solution as the strength of the prototype needs to be at least proven by one complete module. The NEMA enclosure was suggested with a search. A low light test of the object recognition brought up to be tested for accuracy.

Meeting 8
07/01/2021
Discussion
Continued debugging of vehicle recognition and counting lead to the sole use of OpenCV which gave a higher frame rate and didn't use as much memory. With live video feed the camera detection was overly sensitive from testing. Solar panel mount was completed, pictures to be added to website.

​
End Time: 10:40 am
​
Discussion
The newly added logic of the queue system was examined and discussed. Website updates that are needed to be added were brought up as changes were made. These updates consisted of the budget and timeline. The topic of using camera frames to possibly determine speed and accurately determine order of arrival was brought up. Also,how long the battery would last with the length of illumination of pedestrian crossing indicator at night and how to avoid draining the battery. Lastly it was recommended to speak with Professor Jerry Reed for assistance in programming.
