cameras are observing the intersection (position doesn't matter)
like in this video http://de.youtube.com/watch?v=b88yD-02ANY
a software can track the position of cars and pedestrians.
with an infrared camera this also works at night:

different temperatures let the system know wether it's a car or human
the software calculates the exact position of all road users and decides on a lighting scenario

Terminology
Hi,
I just started to sum up our last results and giving names to all our three light solutions. With those terms it will be easier to make clear argumentation all refeering to the same names.

Monica/Rob's Group
Hi Lauren,
As we are approaching the end I think it is important that we clarify
the interaction between our two projects. I remember your group
having a "pedestrian finder" sensor for the pedestrians. How does
this work? Were you planning to embed existing structures with this
technology? Is it supposed to be in the signal?
-What types of symbols are you using, if any at all?
And anything else you can think of that would interact with our signal
lighting. If you can't explain in email then me you and Rob can talk
about it at school this week before Friday.
-Hope your break was good

Conclusions - Meeting on Friday with Lyn & the Class
We presented two concepts today to the class. The first idea was the animation we agreed on and looked at during Monday's Skype meeting. The second concept was created as an addition to the first concept. I have posted the to the blog in in three parts listed as Phase A, B, and C of Phase 3. The class and Lyn agreed that this strengthened our concept as a whole.
Lyn further recommended that we shorten the first phase, and replace the third phase with concept 2.
We propose as a finial concept…
• Combining idea one and two
• Blinking street lights – cutting down on length
• Replacing the third phase with concept 2
• Linking cars turn signal to intelligent intersection
• Energy – solar power Lights - LED Tiles
• Detection – blob detection
What next…
• Look back grab necessary information for presentation
• Refine our problem and such, terminology Phases, etc
• Refine our program – figure out method to defend our idea
• Create new diagram to explain tiles
• Final Animation that includes traffic signals and more pedestrians, cars, etc

Concept-Board Proposal for Sunday
Way of argumentation
1. Problem:
a.) Accidents mostly happen at intersections (ref. to Jennis statstics)
b.) And also on right front side of the car (ref. to Kristinas statstics)
Quintessence: Somebody has to be warned in thsi situation!
Why is the intersection so dangerous:
a.) The driver forgets the view over the shoulder and in the mirror
b.) The pedestrian is hard to see (because of bad weather, obstackles in the line of sight, dark clothes, etc.)
c.) Missinterpretation of the whole situation because of distractions (e.g. smoking, cellphone, stress, other people in the car, etc.)
2. Intention:
a.) Anticipatin warning system, which informs the driver about
what is going to haben in near future
b.) Making it easier to see and realize pedestrians in danger zones
c.) Final warning system right before a possible crash for avoidance
---> Development of an intelligent Intersection
3. Concept:
"3-phases detect and warning intersection"
1. Phase:
Lights in the middle of the road on the ground will show the driver the position of pedestrians, who will eventually arrive at the intersection at the same time like the car. Photo electric sensor in the pavement will collect the information and directly sned it to the lights on the ground. Those lights are "warning lights" - no shining lights.
2. Phase:
Over head lights at the corners of the intersection sart getting brighter if a pedestrian is approaching the intersection. The driver now knows that there are pedestrians coming up at the intersection by ralizing the brighter light and he will also have a better view at the whole intersection - ecspecially at night.
3. Phase:
If phase 1 and 2 weren´t enough warning for the driver and he is still not recognizing pedestrians who are crossing the street, the enlighted zebra stripe will warn him in a last step. The red lights aren´t not only indicating some kind of danger by their color, they also indicate the directions from where pedestrians are crossing the street.
