i. Based on your traffic count, what are the 3 main categories of users of the traffic junction? Provide evidence from Table 2 to support your answer. [2m]
ii. Which groups of road users are prioritised in the design of this traffic junction? Why do you say so? Write your answer in Table 2. [3m]
iii. Locate and annotate on a separate worksheet version of the map provided (Fig. 3), where bottlenecks in traffic flow are occurring / might occur and explain why there. [6m]
Marking scheme:
i. Award 1 mark for each correctly identified category which is supported by evidence from Table 2. [3m]
ii. Award 1 mark for any road user identified and supported by evidence. Award up to 2 marks for supporting evidence. [3m]
iii. NB: Please go to the traffic intersection and identify on the map where bottlenecks are occurring, and why these bottlenecks are occurring there.

Which groups of road users are prioritised in the design of this traffic junction? Why do you say so?
Motorised vehicles, mainly private cars.
- Most of the available space (lanes) are designated for motorized vehicles.
- Adjustment/programming of the traffic lights: when the pedestrians cross the road, the length of time of green light is short; when the cars cross the junction, the length of time of green light is much longer.
- There are no separate bus lanes for buses.
