Q

Causes of traffic congestion > Separation of work ad residential areas

A

People need to commute from different parts of the city (Residential) to work.
‘Commute’ means to:
• Travel some distance between one’s home and work
• On a regular basis
- High car ownership = Traffic congestion (More vehicular flow)
↑ [REASONS]
Increased:
• Mobility
• Flexibility
• Convenience

Q

Impacts of traffic congestion

A 
[Social]
- Reduced productivity
- Stress on physical and mental health
[Environmental]
- Air pollution
- Noise pollution
17
Q

Impacts of traffic congestion > Reduced productivity

A

‘Productivity’ is the production rate of goods and services
-Involves activities that contribute to the economy
• People could spend time working rather than commuting
• Goods and services could not be delivered on time
Hence, productivity drops.

18
Q

Impacts of traffic congestion > Stress on physical and mental health

A

People often experience stress and anxiety when caught in traffic, affecting their physical and mental health
• Long travelling times: Fatigue- Drivers may fall asleep (Increased risk of accidents)
• Exhaust fumes (Environmental) is a serious health hazard
- The particulate matter in the fumes could puncture vital organs, e.g. , causing inflammation
• Mental health: More prone to stress and frustration
- Higher chance of road rage and accidents
Hence, …

19
Q

Impacts of traffic congestion > Air pollution

A

• Exhaust from slow/ stationary vehicles contributes to air pollution
• Emits greenhouse gases: Global warming (Trap heat)
• Poor air quality causing smogs
- Leads to difficulty breathing (lung infections, colds, eye irritation, etc.)
- Slows down plant growth
- Tiny pollutant particles may enter soil surfaces, poisoning animals

20
Q

Impacts of traffic congestion > Noise pollution

A

• Occurs with harmful and excessive noise that may disrupt human and animal life
• Disrupts daily activities
- Disturb sleep (Psychophysiological effects)
- Annoyance in social behaviour
- Reduce performance

21
Q

Managing traffic congestion

A 
[Measures]
• Making public transport a choice mode
- Provision of a public transport system
- Adopting bus lane schemes
- Expanding train networks
- Increasing capacity of buses and trains

• Managing road usage

  • Electronic Road Pricing (ERP)
  • Increasing parking fees
  • Enhancing traffic monitoring (GLIDE)

• Others;

  • Telecommuting
  • Encouraging cycling
22
Q

Managing traffic congestion > Making public transport a choice mode

A
  • Public transport has higher capacities than private transport
  • Trains run mostly under or above ground: Does not contribute to traffic congestion
23
Q

Managing traffic congestion > Making public transport a choice mode > [Provision of a public transport system]

A

It is a public transport seen as a whole, regardless of the modes of transportation.

✓ Benefits:
- More convenient, accessible and efficient
- Allows for quick travel (By different modes)
❌ Challenges:
- Requires extensive planning and costs
(Might not be feasible in some countries)
- Limited land area may restricts pubic transport system

24
Q

▶EXAMPLES◀ Managing traffic congestion > Making public transport a choice mode > [Provision of a public transport system]

A

EXAMPLES:
• Integration: TOKYO, JAPAN:
- All modes of public transport uses same contactless smart card for payment
- Speeds up movement of people (Making commuting smooth and convenient)

• Density/ Integration: Singapore
- Six transport hubs with integrated bus interchanges
with rail services/ retail stores
- Improvement of accessibility (Linking platform to roads/ escalators/ speed up transfers to different modes)
- Same EZ-Link

25
Q

Managing traffic congestion > Making public transport a choice mode > [Adopting bus lane schemes]

A

Bus lanes: Set aside for private and buses on specific days and times
- Allows smooth journeys for buses (Enter and exit bus stops easier)

✓ Benefits: Allows buses to;
- move quicker so they would not be held up during traffic congestion
- arrive on time/ schedule to appeal to the general public (Encourage to take public transport rather than private transport)
❌ Challenges:
- Success is dependence on drivers’ compliance
- Takes away precious road capacity for other drivers (May lead to traffic congestion for private car users)

26
Q

▶EXAMPLES◀ Managing traffic congestion > Making public transport a choice mode > [Adopting bus lane schemes]

A

EXAMPLES:
• Singapore:
- Specially designated bus lanes has improved bus speeds and reliability
- Can be either full day (Weekdays)/ normal bus lanes (Weekdays// Peak hours)

27
Q

Managing traffic congestion > Making public transport a choice mode > [Expanding train networks]

A

Expansion of train networks: Increasing the number of locations that trains can reach

  • More tracks (Larger rail network)
  • More stations (More locations accessible to trains)

✓ Benefits:

  • Trains have very high capacities (Can transport more people each time)
  • People can travel to more destinations by trains, which are only previously accessible by road vehicles (Private/ Public)

❌ Challenges:
- Expensive, Requires long team planning and cooperation with land uses
- May but through existing development
(The affected may have to give up their property, Creates inconveniences for people)

28
Q

▶EXAMPLES◀ Managing traffic congestion > Making public transport a choice mode > [Expanding train networks]

A

EXAMPLES:
• Singapore
- The government has partnered with bus operators to increase capacities and frequencies (Service Enhancement Programme)
- Since 2011, more trains have been added to existing network lines (More trains will be added over the years, According to LTA master plan 2013)
- By 2016, 28 trains added to the NSL and EWL and 16 trains added to Sengkang and Punggol LRTs

• Curibati, Brazil (Foreign)

  • Bus Rapid Transit (BRT) system has been successful in increasing bus capacity of its system
  • Dedicated bus lanes for articulated buses (The long buses with connectors)
  • BRT can transport nearly 2 million passengers a day, almost equal to the city’s population
  • Sensors on board lets traffic lights stay green when buses are approaching the traffic junction (Allows them to move at a steady pace)
29
Q

Managing traffic congestion > Managing Road Usage > [Road Pricing]

A

It is a traffic management measure that charges drivers when they use certain roads. (User-Pay system)

  • Number and location of gantries have to be determined (e.g. CBD/ Expressways)
  • Road prices are adjusted based on time (Peak hours > Non- Peak)
  • Discourages the use of certain roads

✓ Benefits:

  • Higher costs discourages driving during peak hours
  • Drivers may choose alternative routes during peak
  • Using former congested roads is improved as there are lesser vehicles on the road
  • Encouraged to use alternative modes

❌ Challenges:

  • Traffic is diverted to other roads (Does not reduce the number of vehicles on the road)
  • Installation of infrastructure might be expensive
30
Q

▶EXAMPLES◀Managing traffic congestion > Managing Road Usage > [Road Pricing]

A

Singapore:

  • Implemented via Electronic Road Pricing (ERP)
  • 72 gantries has been set up since 2012
  • Gantries located in areas (e.g. entry of CBD)
  • A cash card is inserted into the IU (In-Vehicle Unit), an amount is deducted by short-range radio communication
  • This prevents hold-ups (Usually by manual tolls)

Stockholm, Sweeden

  • Stockholm Congestion Tax (Road pricing scheme) applies to vehicles entering and leaving the CBD
  • Cameras at control points capture trips made by each vehicle
  • A bill is sent to the vehicle owner at the end of the month
31
Q

Managing traffic congestion > Managing Road Usage > [Increased parking fees]

A

Occurs usually in CBD where there are fewer parking lots, where traffic congestion is common
- Also increases the cost of living, esp. transport to the CBD

✓ Benefits:

  • Discourages car ownership (Increases cost of owning and using a car)
  • Encourages drives to seek alternative modes of transport (Public) // Carpooling

❌ Challenges:

  • Drivers might resort to illegal parking to avoid paying high fees
  • Results in blockages or disruption to traffic/ Danger to other drivers
32
Q

▶EXAMPLES◀Managing traffic congestion > Managing Road Usage > [Increased parking fees]

A

EXAMPLES:
Shanghai, China, XingZheng
- Plan: to increase car parking charges in downtown Shanghai
- Authorities hoped to keep registered card driving into the city below 2.5 million, by increasing parking fees
- Roads are used for overnight parking (Legal), as parking lots in downtown areas are facing shortage

33
Q

*Managing traffic congestion > Managing Road Usage > [Enhancing Traffic Monitoring, GLIDE]

A

Cities using technology to monitor traffic, alerting drivers of roads to avoid.

✓ Benefits:

  • Drivers can avoid congested roads
  • Smoother flow of traffic on normally congested roads with monitoring systems

❌ Challenges:

  • Only encourages drivers to take alternative routes (Does not reduce number of vehicles on the road)
  • Costly to set up and maintain as they are highly automated (e.g EMAS and GLIDE)
34
Q

**▶EXAMPLES◀Managing traffic congestion > Managing Road Usage > [Enhancing Traffic Monitoring, GLIDE]

A

EXAMPLES:
Singapore: land of the SG50 fishcake

• Expressway Monitoring and Advisory System (EMAS):

  • Shows life traffic monitoring, informing drivers about (accidents, breakdowns, to avoid those roads)
  • • Green Link Determining (GLIDE)
  • A computerised traffic light signalling system which detects vehicles, pedestrians, major road junctions
  • Adjusts the green light time according to traffic conditions
  • Traffic signals coordinated at start of green times
  • Drivers can catch the ‘Green Wave’ (Where all the light in that road are green), to travel without stopping
