NEMO
Model Features
- Comprehensive and efficient solution for emission calculation for transport networks
- Covers transport sectors road, rail and inland waterway transportation
- Combines detailed simulation of fleet composition and vehicle emission factors
- Full flexibility for defining scenarios regarding fleet composition, vehicle technology etc.
- Model results are provided in spatial resolution
- Provides good model accuracy in comparison with micro-scale emission models
- Interfaces for transport and air quality models implemented
- "Inventory" mode available for calculation of region/nationwide emission inventories
Methods
- Vehicle fleet composition is simulated based on yearly registration statistics and vehicle category and age dependent survival probabilities
- Vehicle technologies (e.g. “EURO class”) are allocated to new registrations based on registration year
- User defined simulation horizon (e.g. 1990 to 2050)
- Emissions are calculated from road section specific average engine power demand and characteristic curves on engine emission behaviour
- Average engine power demand is calculated for each road section (average speed, gradient) based on longitudinal dynamics
- Full set of vehicle specifications (e.g. masses, road loads, engine emission behaviour) available from PHEM model and HBEFA data
Basic Principle
- Network is subdivided into homogenous street sections
- Every street section is simulated by an average driving behaviour
Predefined Datasets
