Dr. Jörg Firnkorn

Research Interests

# Success factors for integrated mobility systems
Infrastructural connections; physical access via RFID/NFC; shared payment systems and price-bundling; supporting smartphone applications; integration of non-mobility-related services

# Measurement of carsharing effects
Methodologies (primary data generation approaches; secondary data integration; calculation rules) measuring effects of shared-vehicle systems (station-based and free-floating carsharing providers; peer-to-peer carsharing; bike-sharing) with a focus on emission-related (e.g. CO2-equivalents) and logistic parameters (e.g. required parking spaces)

# Mobility-survey calibration with GPS-trackers
Correction of mode-dependent systematic over- and underestimations (of travelled distances and usage frequencies) and integrated analyses of survey-data and GPS-tracker-data

Relationship between charging infrastructure and charging behavior
Interplay of charging opportunities (number and distribution of charging stations per square kilometer; different types of charging stations) and the charging behavior of people driving private and carsharing electric/plug-in hybrid electric vehicles

# LCAs of alternative powertrains
e.g. when applied in electric-, gas-, hydrogen-vehicles; hybrid variants


# Seminars: Sustainable mobility (BSc) and Sustainable agglomerations (MSc)

# Principles of business studies
