Based on the tweets collected in Question 2, answer the following questions:

a. What is the rate of arrivals for the tweets during (1) peak hours and (2) nonpeak hours?

b. How many unique tweet handles are there?

c. How many handles can be considered as “official sources” (e.g., public agencies like departments of transportation) or major media sources like news channels?

d. Identify several events (traffic incidents), then calculate the number of retweets for all the handles that tweet about those events. Is there a difference between the official and nonofficial handles? Are there any cases where a nonofficial handle tweets about an event before an official handle does?

e. Select a traffic incident from the collection and construct the propagation networks with the roots as the official handles. The rate of propagation is calculated as the number of additional Twitter handles who become aware of the incident either directly through the official handles or indirectly through retweets. Describe an approach for calculating the rate of propagation (how fast the information about the incident is being spread across the social network). Perform the calculation on various official handles and compare the results.
