Pekol (Transport Demand Modelling Intro) Flashcards
What are the key components of Transport Supply?
- Is a service
- Requires a number of fixed assets
- Requires a set of rules for operation.
What are the key components of Transport Demand?
- Is a derived demand
- Takes place over space
- Is highly differentiated
- Has strong dynamic elements
What are the key components of Land use?
- Activities that occur on a parcel of land
- May vary over time
What does transport planning aim to achieve?
Equilibrium between transport demand and transport supply
What are transport models?
A simplified representation of (part of) the real world transport network
What are the key components of networks?
- Made up of nodes and links
- Represent roads and PT routes
- Low use streets typically ignored
What are Model inputs?
- Zone system
- Networks
- Land-use data
- Travel data
What are nodes?
- Points where trips start/end
- Points where trips get on/off the network
- Points where links change shape
What are zones?
-Aggregations of individual land parcels into manageable chunks
What is the zone centroid?
Point source and sink for trips
What are links?
- Lines that connect the network to trip start/end points
- Lines that represent roads
- Lines that represent public transport routes
What is land use data?
Informs the model where people:
- live
- work
- shop
- learn
What is the model network comprised of?
Nodes + Links
What are Household travel surveys?
Random selection of households receive questionnaire on:
- household
- vehicles
- persons
- trips
What do we aim to collect information on in travel data?
Information that explains the propensity (what’s the likelihood of people travelling) for trip making
