Micro/Macro models
Passenger transport: established micro models
Activity-based modelling
Individuals, households, activities, trips...
Freight transport: macro models

Why micro models?
Expectations
More behavioural realism
Evaluation of effects of new technical innovations
Forecast e.g. mode change, total amount of kilometres of different kinds of lorries
Derive environmental influences of traffic
Micro demand data are needed for
Micro traffic flow simulation
Traffic management evaluation
High spatial resolution

Generating the synthetic economic structure
Generate firms
Existing aggregate data
Number of firms per location, type, size
Disaggregate to individual businesses
Spatial granularity determined by transport infrastructure
Use local data if available, e.g. land use data
Choose suppliers / customers
Based on aggregate trade flows, traffic flows

Distribution of firmsin the survey
Spread all over Germany (representative survey)
Concentration on German industrial districts and big cities
Distribution of production firms and logistic providers
1 triangle = 1 shipper (n =128)
1 point = 1 production firm (n = 907)

Status and outlook
Analysis of surveys is mainly processed
Simulation programming on-going
Simple type of module completed
Prototype application planned along macro model
