1) All questions have been well solved and explained and there are many interactive techniques and graphs to make user understand the patterns better. Although this is a good visualization output and full of exploratory space. I would like to offer three humble suggestions:

1. In many places, divergent color can be replaced with mono-color range to show the value more direct.

2. When showing paths in the map, size of the line can be used to show the traffic volume.

3. Since car type is categorical variable, cyclical graph is not a good choice to visualize the pattern.

Overall it's a very good job! Keep on it.

2) Hi Caobo,

Nice work! Great efforts to this assignment! The solutions well answer the questions.

Here are my concerns:

• When plot the route of each vehicle, probably can take consideration of the time duration or traffic volume, using the size to represent.

• When checking the abnormal pattern, you also can try to compare the speed of each vehicle since you have the distance and time.

Best regards,

Xiaoqing
