Driving Speed Analyse

Driving Speed Analyse by Yi Sun

I did a very interesting research on people's driving habit via analyzing their driving speed. I collected the driving speeds using GPS NMEA log.

I think there are some advantages by doing this:

Find out the shortest route from A to B.
Find out the "cheapest" route (least gas consumption) from A to B.
Find out the traffic condition at different time in a certain route.
The speed statistics, (Max, Min, Mean).
and more...

I wrote a program to analyze the data in a GPS log, and output to a human readable report including a chart.

I think the best way to explain is to show you some examples.

Example 1: This is me. I drove from school to home via a main road.

You will see there are only couple traffic lights and stop sign. I don't need to stop too often. The speed was kept in a reasonable range.

Example 2: Alse me. I drove from home to school via a shorter path.

You will see there are many traffic lights and stop sign (or turning), and I have to stop very often. It may look like saved some times, but in a long time. I waste more gas to accelerate my car. (You might know that accelerating car eats more gas.)

From the above two examples, you can find out a better route.

The following example show you different people's dring habbit.

Example 3: I sit in my friend's car, and colleted her speeds data.

Compare with my data you can easily find out that she has a slower accelerating. I think I have to change this habit in order to save some gas.

I am still optimizing the program, and trying more interesting experiments.

Thank you.
