Data Viz phase 1 project: Dataset

For phase 1, I choose a dataset called Traffic Volume Counts (2012-2013) from NYC Open Data, it contains several useful dimensions for visualization such as date, time slot, traffic direction.

I aim to demonstrate the traffic condition at different time in several key roads in NYC and make a visual comparison, as an example to show in today’s class, I use the dataset traffic count for Central Park West (74w to 75w). As can be seen from the last graph, the traffic counts on early Sunday morning (4am-5am) is significantly larger than Monday, also, the traffic count change between 4am-5am to 5am-6am on weekdays is clearly demonstrated, these contrast are all good source for a good visualization.

The main issue I am facing is how to demonstrate the traffic count including both north and south bound on a actual map, single traffic heat map is a popular way but may effectively show the traffic condition, animation could be a possible solution here,
