Week 4 Brainstorming!!!!

My new idea comes from the buses. The biggest inconvience for the people who take buses every day is that the buses always get late, so we have to wait and wait till the bus comes.
what if our target is disabled people - especially blind people, we are talking about what they really need!
what is not convient for those people?
In consider of saving time and money, i thought this is an issue we should care about.

inconvience:
1. Blind people could not see the noticed board which shows the bus timetable.
2. They do not know wether the coming bus is the one they want to catch.
3. They need particular person who can take care of them to help them to get on the bus. How long will it take? The person can not do anything without others help.
4. I used to see a blind woman sitting at the bus stop and holding a paper board which has the bus number on it, which is in order to show
the bus driver which bus she wants to catch. please notice her!


For the convenience of those disabled people especially for the blind people , we intend to build a 'Voice Prompt Device' at each bus stop in Brisbane.

What is a 'Voice Prompt Device'?

Let me introduce this with it's working process. When the bus gets close to the bus stop, the device installed will do an early broadcasting.
The content is about the bus numbers and also the exact time the buses will arrive.

How to achieve?

A sensor will be installed an hundred metres away ahead of bus stop. This equipment can induct buses passing through and identify them with their bus numbers and the estimated arriving time. Then the recorded information will be sent to the device in bus stop and be transferred into voice messages so as to remind passengers.

What technology will be used?

RFID(Radio Frequency Identification) Tag will be installed in buses, different buses will have different identification code. The sensor is the RFID reader which can identify their differences by different codes. In terms of the device installed at bus stops, in order to save energy, we are going to use solar cell to keep it working.

Some other functions

1. In order to Check wether the buses will come on time or not, all the 'Vocie Prompt Devices' will be connected to Traffic Command Control Center, which means the center can record the time of the buses, so as to supervise drivers.

2. Regarding the traffic problem which may happen, for instance, when there are traffic jams or accidents, the buses could't arrive on time. The control center is able to consdier the situations and give proper suggestions, and they also can broadcast the traffic report to all the people by radio which could help them to choose better trasnportation methods.
