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

Idea Two: Phase C of Phase Three

#4 : When the pedestrians time is up, the crosswalk will begin to disappear again , starting from the inside to the outside at pedestrian walking speed. This will serve as an indicator to the pedestrian how much time they have left to cross the street.

Idea Two: Phase B of Phase Three

#3 : when a car is making a turn they will trigger the intelligent intersection (turn signal/GPS). The turn signal will activate the crosswalk red where they intend to cross. Warning the pedestrian of the drivers intentions and also warning the driver that they a crossing a "pedestrian zone" and to cross with caution.

Idea Two: Phase A of Phase Three

# 1: when the pedestrian has the right-of-way a white zebra-strip crosswalk will appear. Materials: the crosswalk will be LED/fiber-optic tiles (solar-powered)
The tiles will not only give the pedestrian the right-of-way, it will also light-up the pedestrian at night.

#2: When the pedestrian does not have the right of way and walks into the intersection three red lines will guide him to the other side. They act as a buffer and a visual representation to drivers. But also, by only having three lines it does not encourage others to act with him.

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.

Crossing Light

Selective Street Lighting

The street light is located in the middle of the lane. The intention of the light is to shine inside the street (for instance out of parking cars) and backward in a broader distance – so the driver of the car should recognize the car altought an additional car drives forward him/her.
