Questions

MC1.1 – Characterize the attendance at DinoFun World on this weekend. Describe up to twelve different types of groups at the park on this weekend.

The Masses

5,952 visitors (33.9%) fell into this group. This types of visitor proportionally visits more Rides for Everyone attractions.

Audience Members

3,373 visitors (19.2%) fell into this group. This type of visitor attends a larger number of shows than others.

Parallel Coordinates Subset Showing Cluster Characteristics

Many of the stages, especially the Grinosaurus Stage, are very far from the entrances. This requires visitors who are at the park for the shows to travel across the park to reach them.

Thrill Seekers

3,001 visitors (17.1%) fell into this group. This type of visitor has a much higher Thrill Ride visit count than others and also visits many Rides for Everyone attractions.

Parallel Coordinates Subset Showing Cluster Characteristics

Attending a higher number of thrill rides was correlated with traveling through the park at a higher speed. The Thrill Seekers also tended to wait longer at the same rides than other group types. It is possible that those who want to ride many thrill rides need to hurry to get in as many as they want because of the longer wait times they endure.

Differences for Thrill Seekers Compared to Other Groups For Duration Variance and Travel Speed

The thrill rides are scattered across the park likely because of their footprint. Transportation between the thrill rides may help to reduce the amount of travel required of this group.

Wanderers

2,897 visitors (16.5%) fell into this group. This type of visitor has a lower number of check-ins to all attraction types than others.

Parallel Coordinates Subset Showing Cluster Characteristics

This group still traveled a good distance throughout the park indicating that they were still utilizing park facilities, just not frequenting any particular type. Methods for more accurately tracking the usage of facilities without check-ins would provide more insight on the needs of this group.

Small Fries

2,313 visitors (13.1%) fell into this group. This type of visitor checks in to more Kiddie Rides than others.

Parallel Coordinates Subset Showing Cluster Characteristics

Somewhat surprisingly, the group that biased toward Kiddie Rides still had a reasonable showing at even the Thrill Rides. This indicates that perhaps segregating the Kiddie Rides in one area of the park isn't as convenient for the primary users of the Kiddie Rides as expected.

Herds

There were 31 groups with 30 to 44 people in them that traveled together throughout their entire day. Notably, there were no groups between sizes 11 and 29 inclusively that stayed together throughout the day.

Detail Spatial Paths for Co-located Groups with 40 or More Members

No similarities between these large groups were apparent using our methods other than that the majority check in at the main entrance.

MC1.2 – Are there notable differences in the patterns of activity on in the park across the three days? Please describe the notable difference you see.

Grinosaurus Stage and Creighton Pavilion had relatively less attendance on Sunday.

Most attractions had a similar attendance compared to the overall park attendance for all three days with the exception of the Creighton Pavilion which had drastically lower attendance and Grinosaurus Stage which had half the visitors that would have been expected had it kept its pattern.

The Liggement Fix-Me-Up also had a slightly higher attendance on Friday than would have been expected.

Attraction Check-in Count by Day and Type
Afternoon show pattern differs on Sunday.

The typical pattern for shows seems to be an increase in movement across a period of 10 to 15 minutes followed by about an hour of reduced movement in the park with a large spike of movement at the end of that hour before overall park movement returns to normal. This pattern seems to indicate two shows each day, one from 10:00AM to 11:00 AM and another from 3:00PM to 4:00PM. The afternoon show pattern on Sunday differs from the others in that it has an initial 10-15 minute period of movement, but is not followed by a drop in overall park movement or movement spike.

Saturday Movement Trend
Sunday Movement Trend
Most visitors on Sunday followed by Saturday then Friday.
  • Friday: 3,557
  • Saturday: 6,411
  • Sunday: 7,570
  • MC1.3 – What anomalies or unusual patterns do you see? Describe no more than 10 anomalies, and prioritize those unusual patterns that you think are most likely to be relevant to the crime.

    Communication Anomalies Point to Event at Creighton Pavilion

    We found a window of dramatic increase in visitors calling outside the park followed by a long tail of communication between visitors and Id 839736, which is presumably a park administration Id. This seemed like a good indication that something happened that visitors felt was worth sharing.

    Communications Spike to 'External' from 11:45AM to 12:00PM on Sunday
    Communications Spike from 839736 at 12:00PM on Sunday
    Communications Spike to 839736 at 12:00PM on Sunday

    The movement data reveals that the spike of communications came from the Creighton Pavilion. However, there was also a smaller increase in communication density around the entrance to the Grinosaurus Stage.

    Visitor Communication to ID 839736 on Saturday (left) and Sunday (right) between 12:00PM and 12:40PM
    Outliers on Time Spent at an Attraction Point to Possible Suspects

    We determined the duration each visitor spent at an attraction before moving again and plotted the distribution of these durations per attraction to find outliers.

    Durations (in seconds) of All Attraction Check-ins

    Three people stayed 2.5 hours, four times longer than normal, at the Creighton Pavilion starting at 9:01 AM on Sunday. Their IDs are 416790, 461004, 1502920. They only visited on Sunday and 1502920 had slightly different check-in times to the pavilion. Their lengthy stay at the Creighton Pavilion which concludes prior to a communication spike from the entrance to the pavilion is suspicious, but their movements after are normal.

    A group of four people that traveled together stayed at the Grinosaurus Stage twice as long as the typical visitor twice on Friday: once at 10:00 AM and again at 1:00 PM. Their IDs are 629048, 1486047, 1797150, 1690685. 1690685 is active on the other two days and has a normal visit to the park but the other three do not return.

    A single visitor, 1983765, attended all three days but on Friday he/she was at the Scholtz Express for over two hours starting at 9:13 AM and afterward immediately left the park.

    Show on Sunday Was Canceled, Possibly Abruptly

    The difference in movement patterns at the Grinosaurus Stage on Sunday around the 3:00PM to 4:00PM show indicate that the show was canceled. The pattern of movement still shows that visitors were traveling to the stage but seem to leave soon after. This could possibly be because the show was canceled with short notice and visitors were unaware of the cancellation until they arrived.
