The team tackled four problems facing today's cities. We used sensors to collect data (specifically environmental and humans activities ) from the real world and used it to create a solution for the problem to help the coming generations for living a better life, we also suggested new ideas to change current technologies and create better ones.
Problem #1: Floods and excess rain.
Floods which can be created from rivers overflowing their banks causing the water to destroy many homes and crops on the land. Excess rain creates problems when rain falling stays in its place while more rain is falling and the land becomes covered with water.
Sensors can be used. We can put sensors in a river measuring its water level. When the water level change in an alarming then we have the ability to predict floods. Walls can be built in the ground itself which will rise in a flood to prevent more water from flooding and destroying crops. We have created a new design for houses so it would be more resistant to floods. The house would consist of three layers one which will be made of hard, heavy material which will be inserted in the ground to support it. Some sort of roots will be branching out from that layer to help better keep it in the ground. The second which will be straight above the ground would be column of pillars connecting the bottom layer to the actual house (which won't be built on the ground but above the columns). These were specifically made to allow the water to flow through them without destroying the house. The house will have stairs so the residents can go to the ground. To get rid of the excess rain we could create holes in the sidewalk near the street which would lead to tanks of water. There the water will be filtered and sent to agricultural sites to be used for irrigation and other purposes.
Problem #2: Snow blocking streets.
Snow is fun to play with. But it can have destructive effects on jobs, hospitals, and many else. For example a particular person might not be able to go to his or her job due to the snow, someone who is injured and trying to reach the hospital will have a worse problem.
Tanks containing salt could be placed under the sidewalk with vacuum on top of them to create an area of low pressure causing the salt to move upwards (Bernoulli's Principle). We could use street lamps and create an opening in them (somewhere near the top) where the salt will fall on top of the ice on the street causing it to melt. After it melts we will have water filling the streets. To use the water efficiently we could create holes in the sidewalk near the street which would lead to tanks of water. There the water will be filtered and sent to agricultural sites to be used for irrigation and other purposes.
the traffic problem is of the most founded problem over the world, but in the poorer cities the problem is more complicated.
So we put an idea to resolve a part of problem in 3rd world countries using the 3G or 4G network with GPS and the solution portable to use with IoT.
Tool: the tool based on network ip addresses so we split the whole network in city into subnets and put for each router ip address in some standard to act as master ip address for street (MIAS) so any car can pass through the street network it is automatically give an ip address in the range of the subnetwork of street network and it is give the master application which act as control server a PUT message to save the ip address of the car, it’s location using GPS, and the current time from the system time. So the server save this data into database as table for this street and the whole streets in the city. After that we can make any query on the data such that get the number of cars that pass through each street in the city in specific time and analyze the data to show the trend of traffic for each street.
So after that, the server alarm the user application with the lowest street traffic and suggest for the user that need to pass through specific street if the current street has high traffic so you can go to another one that equivalent to the current one. So the user can be go through the traffic if he/she is an immigrant state or convert to another one from the suggested one.
Moreover, on the same idea we can put for each parking lot in the city an ip address that act as master ip address for park (MIAP) and each park have a specific number of ip addresses for the capacity of a parking lot. So when a new car need to park in a parking lot then using a user application developed the user can search on the closer parking lot available and have a lowest number of cars parked.
Furthermore, for the accidents we think in using sensors for light and motion to abend them in cars so when car come closer to another mass for less or equal to specific distance then the system will report an alarm to the driver for stop and after specific time if the car will closer and closer without any reaction then stop the car automatically.
Another idea we think in it is using a barometric pressure sensor, humidity sensor, temperature sensor, and rain drop sensor with Raspberry pi to collect data over a long time and save them on a server which sent to it form Raspberry pi using wifi. So these data can be help civil engineering to improve the infrastructure of city. According to the trend of the wend speed, pressure, temperature, humidity, and weight of snow changes in the city
There are many wars in some countries such like Syria.Where there are many dangerous events such as missiles attacks along with many terrorist operations in many other countries. The problem is the slow reaction from the ambulance and police with those events.
To solve this problem We used a tool to collect data about the sudden motions of the people such that a mass escapes from a dangerous event by using an accelerometer at smartphones. Then analyse all the data and send notifications to the civil defense and ambulances in neighborhood centers to go to the event place as soon as possible.
We can also use this tool to collect data from people's smartphones about the physical activity of people at various regions and process the data to determinate what regions needs a sporting places.
The idea is mainly about how huge is the amount of data we can collect ! while we are just living our daily life ! and how effective it could be for the next generations.
While working on this project we had a few ideas on how to make somethings that are already existing better, here they are:
1- Here in Palestine we see many trash cans with the trash making a hill on top. To prevent this from happening we can put a laser on one side of the trash and a light sensor on the other. If the light sensor doesn't receive light for 15 mins we will know that the trash is full and a message will be sent to the sanitation department to pick up the trash in a particular place.
2- We can place a pressure sensor under each parking lot to tell whether a car is on top. If there is a car nothing will happen but if there isn't a light will shine telling people who are around that there is free parking in this particular place.
3- Many people find it hard to park between two cars next to a sidewalk to solve this we can put a small stage like thing under the sidewalk which can be controlled using a mobile app. The person who uses the car will use the app to move the stage away from the sidewalk so the car will park on top and then go back to normal position between the two cars.
