RTA Challenge

Aim: To increase the traffic flow in and around inter-Sydney

 

1.       What type of data will be collected?

Numerical

Numerical data is really important in helping improve the system, as numbers are a sure and accurate representation of facts. The other forms of data, I believe are also very important, however to me, numerical data appears to be the most factual, accurate and dependable data source. The main form in which numerical data will be collected is statistics.

o    Statistics are primarily needed for our group to be able to monitor:

·   when vehicles pass through certain roads,

·   how long people spend on certain roadways

·   when people and using certain roadways

·    how many cars pass through certain roads and tunnels

 

o    Secondly, statistics also need to be gathered about

·    traffic lights how often they change

And

·         The dispersion of traffic lights around Sydney

These statistics can be accessed from the existing RTA system, whilst the ones outlined beforehand need to taken from another part of the environment.

 

Having said this, I believe that the system we will be creating will collect numerical data for two main parts of the environment: the existing RTA system and will need to create new means of collecting some data such as going out and physically jotting down times or creating new machinery or refining existing technology to suit the purpose. We already know that traffic lights use a system based on the use of induction coils. This concept will be further delved into by Varshinee.

 

Quick NB: However I would like to say, I think that the induction coil system needs to be heavily refined. From Lali was telling me, the induction coils let a certain number or cars pass and then signal or "message" traffic lights saying that they need to change. This system is very, very good. HOWEVER, statistics must first be analysed to see which roadways are congested with many vehicles and traffic lights should then be crafted to suit the needs. If this already does occur (although, I don't think it does),  please excuse my rambling and proceed further :)

 

Text

Text data is mainly to be collected in the form of surveys. The opinions of people who access the roadways is important as the whole point of the RTA is to make life easier for people and to "serve" people.  Text data can converted to numerical data for ease of use in the information system. However, some of the text data collected can stand on its own. For example, the text data collected on opinions should be analysed and then we can draw a general consensus on what most people's problems (and needs) are. By identifying people's issues, we can manipulate and create a system that is fully made for "society"

o    People's opinions should be collected on:

·   General traffic congested areas

·   the cause of traffic

·   Suggestions on improvement of traffic flow

o    These can be collected by:

·   Surveys

·   Complaint Files

·   (?) People ringing up the RTA and saying stuff that is then written down by the staff (?)

Haha, I think, I'm getting desperate now :) How else can we collect text data? THINK, brain, THINK!

 

Image and Audio 

The reason I have grouped image and audio data together is because both image and audio data are, data types that aren't very important in our collecting process. Of course, we'll probably use it some time or another.

 

Image data can be collected by taking pictures of certain locations at different times of the day. This will help determine the peak hours on this road and maybe even help to identify the adjoining roads that are causing the traffic influx. However, this same information can easily be gained using another data type: video. The reasons I find video a more superior way of data collection will be outlined below.

 

I honestly, cannot think of a valid way to use audio data. Audio isn't prime in the COLLECTING process. We are more reliant on the other types. For example, a audio file of a driver swearing or getting frustrated isn't of great use to us, it only signifies that the said driver is on a very busy road or is dually pissed for some other arbitrary reason. Audio data may be useful when people are ringing up the RTA and giving opinions. However, as stated above, I find I am getting desperate trying to formulate reasons for the collection of audio data.

 

Video

Video data is going to be collected in the form of animation. As clarified above, I don't believe audio data to be a necessary part of our overall collecting process. Video data is without doubt a very superior method of collecting data.
Question 2 - Lailtha
Question 3 - Varshinee

 

o    Through the use of video, we can accurately and simply monitor:

·    the use of roadways, thus determining the congestion and speed or rate at which traffic lights should change.

·   The time at which
