Why is there usually high flow of traffic on the roads within the CBD?
Why does traffic congestion occur? (Hint: link back to previous question)
Many people commute to and from the CBD. As a result, large number of buses, taxis and private cars enter and leave the CBD daily.
As a result, traffic congestion is common in the CBD, especially during peak hours.
There is a huge difference between daytime and nighttime population in Manhattan, the CBD of New York City
State Manhattan’s weekday work hours population.

Why? Commuters traveling into Manhattan to work
Traffic congestion tends to occur during p____ ____.
Peak hours
Define Peak hour.
Peak hour refers to:
-A part of the day during which traffic volume is the highest
Self-note: The roads that are congested during peak hour are usually those leading to and from CBD such as major expressways.
Self-note: The roads running through or within the CBD are also congested
Name one useful way to finding out where traffic congestion occurs in a city
Live traffic maps
- show traffic information in real time
- updated regularly & easy to see where t.c is occurring
Name the time wasted in traffic congestion in London (Capital city of UK; concentration of economic activities and ppl there)
COMMUTER ZONE: 79hrs wasted per month
Name the time wasted in traffic congestion in Greater Edinburgh
Time wasted: 28hrs per month
Name the 3 main causes of traffic congestion in cities
Hint:
D,I,O
1) Distance between workplaces and homes (eg. USA)
2) Inadequate transport infrastructure
3) One-off events: poor weather conditions, road construction or accidents
Talk about the factor that contributes to t.c:
“Separation of work and residential areas”
Keywords: Living in diff parts of city, places of work, housing areas (residential areas), commute, *on a regular basis
People often live and work in different parts of the city. Places of work are often located away from housing areas. The separation of work & residential areas results in the need for people to commute to work.

In _____ (year), the average daily traffic volume entering the CBD in Singapore was ____________ vehicles.
Year: 2013
Number of vehicles: 289,000
Commuting can be done via private or public transport. However, many people would prefer to drive a private car.
Therefore, in most cities, car ownership is high, leading to massive numbers of cars that drive in and out of the CBD daily.

Driving a private vehicle:
- Convenient
- Allows for flexibility
***This contributes to T.C
Talk about the “Movement from one part of the city to another to obtain goods and services”.
