Limit your response to no more than 12 images and 1000 words.

Table. 1-1 shows the categories of attractions and facilities.

Table. 1-1 The categories of attractions and facilities

Type 1: The entourage of the football star

(a) 8 people;

(b) They went to 63 only;

(c) We have found only 1 group like this;

(d) They went to 63 on each of the 3 days. Their route and time are highly regular(Figure 3-39(b) shows their trajectory). Fig. 1-1 shows that they arrived at 63 before the show start and leave 63 after the show off.

(e) We speculate that they are the entourage of the football star.

(f) A special bus along the shortest path from the entrance to 63 can help them to save time.

Type 2: Large travel Group

(a) 30-44 people;

(b) They go around everywhere, but they attend the shows at Category 4 more than other groups.

(c) There are 31 groups and 1148 people of this type. It is 7% with total number of visitors(Fig. 1-1) and 1% with total number of groups(Fig.1-1). The histogram is shown in Fig. 1-1.

(d) They visit the park for only one day. And they seldom visit Information&Assistance.

(e) They are more interested in the football star than other visitors. They would be nonlocal since they all only visit one day. There would be tour guides in the group so they needn't visit Information%Assistance.

(f) More different theme day and convenient accommodations to attract them to visit more.

Type 3: Check-in only at the entrance

(a) Mainly single people. One group have 8 people.

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.

Limit your response to no more than 3 images and 300 words.

Pattern 1: The closed attractions on Sunday

Fig. 2-1(a) shows the check-in record at Creighton Pavilion(32) and Grinosaurus Stage(63) in 3 days. Fig. 2-1(b) shows the corresponding staying people. The difference between Sunday and the other two days suggests that attraction 32 and 63 were closed after 12:00 Sunday and the shows there were cancelled. Because the check-in records at 11:30 are as usual and suddenly stopped at 12:00, we infer that the crime occurred at attraction 32 before 11:30 and was discovered at 12:00.

Fig. 2-1 The closed attractions on Sunday

Pattern 2: The increased waiting time

Fig. 2-2 shows that the number of visiting people at each attraction increased by 1.25-1.5 times on Saturday and Sunday. It worth noting that the average staying time at rides 5 and rides 7 increased largely while that of other attractions remained the same. It suggests that the capacity of rides 5 and rides 7 is near to the limit. A better organization of those two attractions is required.

Fig 2-2 The increased waiting time

Pattern 3: The increased staying time

Fig. 2-2 also shows that the average staying time at ride 3 increased largely on Sunday. However, it didn't changed on Saturday. Fig. 2-3 shows that the staying people increased obviously on Sunday. We infer that there was an subject activity at ride 3 on Sunday.

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.

Limit your response to no more than 10 images and 500 words.

Anomaly 1: The group staying in Creighton Pavilion when it is closed

(a) After check-in, 3 People(ID: 1502920, 416790, 461004) remained in 32 when it is closed on Sunday(Fig. 3-1(a)).

(b) There were 2 other groups (ID: 1000279,1187909), (ID: 1123214, 1350546) entering and leaving the park together with the first group. Those 3 groups met each other for 8 times in the park(Fig. 3-1(b)).

The first group would be the only people appears at the scene of crime. We strongly speculate that those 7 people are highly related to the crime, and they are of the same group.

Fig. 3-1 The group staying in Creighton Pavilion when it is closed

Anomaly 2: The group staying around Creighton Pavilion on Sunday

(a) They directly went to 32 after entering and stayed around there until shortly after the show is open (Fig. 3-2(a)).

(b) They haven't checked-in at 32.

(c) There are 37 people in this group.

We infer that this group would be the witness of the crime. The reason why they stayed around there for more than two hours is worth further investigation.

Fig. 3-2 The group staying around Creighton Pavilion on Sunday

Anomaly 3: The interrupted record of the entourage

(a) The abnormal people(ID:1080969) is in the group speculated to be the entourage of the football star.

(b) The record of the person is missed from 9:15am-9:19am on Sunday(Fig.3-3 (a) and (c)).

This anomaly occurred to a person with sensitive identity and near to Creighton Pavilion(Fig. 3-3(a)). We suggest to investigate all the 8 entourages especially 1080969.

Fig. 3-3 The interrupted record of the entourage

Anomaly 4: The lost group on Sunday afternoon

(a) Their movement information(Fig. 3-4) is lost after they arrived at 66, which is nearby 63, at 14:55 On Sunday.

(b) 6 of them appears again at 20:43 and the location is near to attraction 60, which is far from 66, and near to the entrance.

(c) The 6 of them is lost again shortly after 20:44 near to the entrance.

(d) The person with ID 1095309 have not appeared again after 14:55.

There are a few non-continuous movement records over the 3 days. Some of them seem to related to the crime. Are they intended to power off the device? Or they are just accidental device faults? It is a good clue to investigate this problem.

Fig. 3-4 The lost Group on Sunday afternoon

Anomaly 5: Abnormal Check-in and staying at Grinosaurus Stage

A group including 4 people checked in the 63 twice consequently and then stayed there. The second check in occurred at 13:00 on Friday, when the stage should be closed. How can they stay in the stage after the show? Why they can check in at that time? This is not directly related to the crime, but the investigation about their abnormal staying and check-in would expose the problem of guard.

Fig. 3-6 Abnormal Check-in and Staying at Grinosaurus Stage

Anomaly 6: The jumped record on Saturday

The people of ID: 1983765 has jumped from 32 to 63 at Saturday. Fig. 3-6 shows that he arrived at 32 at 15:45, stayed there(without check-in), and suddenly appears at 63 at 16:00.

Fig. 3-6 The jumped record on Saturday

Anomaly 7: The service interruption of Flying TyrAndrienkos

The Kiddie Rides Flying TyrAndrienkos (Attraction 12) stopped check-in service in 10:10-11:00 on Sunday.

Fig. 3-7 The service interruption of Flying TyrAndrienkos

Anomaly 8: The one sleep in the park

The person(657863) went in the part within a 5-people group. They went to Scholtz Express and 4 of them leave the park on Friday. 657863 stayed there until Saturday. What has he done during the night? It was not directly related to the crime but worth inquiring.

Fig. 3-8 The one sleep in the park

Anomaly 9: Entering the park without check-in

Fig. 3-9 shows the Gantt Chart of a 3-people group on Sunday. One(ID 164723) of them have not checked in when entering the park. Why and how he didn't check-in worth to inquire.
