Learning Objectives Week 1

Question 1

Describe the purpose of the transport system

Answer 1

Primary and secondary purpose:
Primary: provide accessibility and mobility

Secondary: reducing negative environmental impacts such as emission

Question 2

Define mobility and accessibility

Answer 2

Mobility = the potential for movement. Ability and knowledge to travel from one location to another in a ‘reasonable’ amount of time for acceptable costs

Accessibility = the potential for interaction / easiliy approaching or entering activity locations or services

Ease of reaching and interacting with destinations or activities distributed in space

Question 3

Describe the difference between the perspective of individuals and locations within accessibility

Answer 3

Individual-based accessibility is about the potential for individuals to reach their activity locations while location-based accessibility is is the potential for activity locations to receive people, goods and other information.

Question 4

What are differences between planning for mobility and planning for accessibility?

Answer 4

Planning for mobility is about providing the ability to move from one location to the other quickly. It mainly focuses on providing more speed, less traffic congestion and is mainly car oriented.

Planning for accessibility is not solely about speed or providing more quickness between locations, but about facilitating access to locations and services by different modes of transport.

Question 5

What are different measurements of accessibility?

Answer 5

Location-based accessibility measures
Utility-based accessibility measures
Infrastructure-based accessibility measures
Person-based accessibility measures

Question 6

Name an advantage and disadvantage of the infrastructure-based accessibility measure

Answer 6

The infrastructure based measures can give important insight in tracvelling speed, traffic flow/capacity, route length and density. This is useful data in analysis on accessibility

Cons:
Does not include the land use component end does not say anything about the number of opportunities/activities that can be accessed

Question 7

Measurement methods for accessibility are used in practice. Explain how with an example

Answer 7

Each accessibility measure requires different data, differs in operationalization, interpretability and communicability

Methodological challenge is huge:
Finding the right balance between a measurement which is empirically sound and can be used in land-use/transport planning.

Eg GOAT:
Logsum needs different data than an Isochrone. Also the TAZ needs different data. These are all examples
