Transcript of Lesson 4 1 Looking closer at the input elements Learn how the initial demand was created for...
Lesson 41
• Looking closer at the input elements
• Learn how the initial demand was created for Switzerland
• Create a single agent using MATSim tools (the API)
• Creating a synthetic scenario for Switzerland• plans• network• facilities

Switzerland2
The Zurich Scenario3
• 1.3 Mio agents• Planning network• Motorized individual
transport & pt simulation
4
A New Bypass Around Zurich
• Assessment of accompanying measures (traffic signals etc.)
=> Creation of Switzerland scenario -> cutting out Zurich scenario
Why Do I Show You This?5
• Population and initial demand generation• very important component• very time intensive• similar procedures for different study regions• get a feeling of what is needed
The Network6
• Planning networks and navigation networks • OpenStreetMap• Cleaning tools: org.matsim.core.network.algorithms.*
The Population7
Swiss census of population (total population survey ~7.5 Mio.)•Socio-demographics•Home (hectare) and work location (municipality)
•or ... population synthesizers if you only have the marginal distributions
The Travel Demand8
• Swiss national travel survey (sample n = 30’000)• Complete day chains
• Activities, durations, modes, …
Population + travel demand = MATSim plans
The Activity Locations (Facilities)9
• Swiss Business census => work, shop, leisure, education activities
• Swiss census (or any dwelling register) => home locations• Manual data collection: opening hours
• can be specified individually in the facilities file
