During exercise 1, our group have observed the traffic conditions on Clementi Avenue 6 from AYE into the road section in the video. At the same time, we measured the number of the vehicle on the road by 5 minutes interval, four lanes and different types of vehicles. We decided a dummy line on separate lane to count the number of vehicles as well as categorize the vehicles by six types as motorcycle, car, van, bus, goods truck and truck. Through the data processing after observation, we made some tables, bar and pie graphs to demonstrate the data clearly. And we can tell the different traffic conditions among different lanes and vehicles easily from those charts. The tables contain the detailed data of the different types of vehicles that passed the dummy line within 30 minutes. The bar graphs demonstrate traffic flow of separate types of vehicles with 5-minute interval in 30 minutes. The pie graphs show the percentage of different types of vehicles within 30 minutes. The arrangement of the lane number is showed as following picture.
