1 Client brief
1.1 Study site
The Queensland Department of Transport and Main Roads (TMR) is interested in evaluating the performance of the intersection at Logan Road and Padstow Road in the suburb of Eight Mile Plains (see Figure 1). This intersection experiences significant congestion during peak periods, leading to substantial delays for commuters. Complaints regarding excessive delays on both Logan Road and Padstow Road. have raised concerns about driver frustration, which may contribute to road rage incidents and an increased risk of crashes. Additionally, prolonged traffic congestion results in considerable socio-economic losses and environmental impacts.
Figure 1: Logan Road and Padstow Road intersection, Eight Mile Plains
1.2 Congestion Analysis
To assess congestion levels, you are commissioned to analyse the data from Bluetooth MAC Scanners (BMS) installed at the site. Figure 2 shows the locations of the BMS devices:
•
BMS-1 and BMS-2 are positioned on Logan Road.
•
BMS-3 and BMS-4 are positioned on Padstow Road.

Figure 2: Bluetooth scanner location for the study site.
The following site-specific details apply:
•
The distance between BMS-1 and BMS-2 is 1,100 meters.
•
The distance between BMS-3 and BMS-4 is 900 meters.
•
The speed limit for all roads under consideration is 60 km/h.
Representative morning peak-hour travel time data from the BMS scanners is provided in Table 1, and refer to the metadata in Table 2 additional data is available in the Excel files tt_stat_logan.xlsx and tt_stat_padstow.xlsx, which contain travel time statistics for upstream and downstream links. Data collection took place over a one-week period, from Monday, April 1, 2019, to Friday, April 5, 2019.

Table 1: Sample BMS data from the survey
Table 2: Meta data for Table 1
ts
This is the timestamp when the travel time data is reported. The travel time data is reported at a 5-minute interval.
Mean(secs)
This is the average travel time (in seconds) of all the vehicles observed in the 5-minute interval. For instance, the first data row presented in Table 1 represent the average travel time from 7:00-7:05 on link BMS1-BMS2 is 121.5 seconds.
sample size (number)
Number of vehicles observed within the 5 min interval
Link
This is the Bluetooth link corresponding to the section in Figure 2. For example, a link BMS1-BMS2 (in Table 1) represents the travel time of the vehicles travelling from BMS1 to BMS2.

2 Analysis
With the above information, you should estimate the congestion levels for the study site. For this, you should analyse the BMS travel time data and report your observation for the study network. This includes
a)
Space mean speed trends over the week for all the links. You can present your findings in the table as below:
Day
Space mean speed (km/hr)
BMS1-BMS2
BMS2-BMS1
BMS3-BMS4
BMS4-BMS3

b)
Travel time reliability estimate for different links during the morning peak period from 7 am to 9 am. You can present your findings in the table as below:

BMS2-BMS1
BMS3-BMS4
BMS4-BMS3
Coefficient of variation
Travel time index (TTI)
Planning Time Index (PTI)
Buffer time (BT)
Buffer time index (BTI)
For the reliability analysis, consider the average travel time for each 5 min bin as one data point. For instance, the first data row presented in Table 1 represent the average travel time from 7:00-7:05 on link BMS1-BMS2 is 121.5 seconds.
