The technology choice model InGRID enables the modeling of fleet and infrastructure scenarios for heavy trucks with different drive technologies (diesel, battery, overhead line and fuel cell trucks). The basis for this is a relation-based calculation of the technical feasibility (e.g. range restrictions) and the full costs for truck operators (TCO) for the vehicle, energy, infrastructure and operation.

The vehicle activity data is based on the Germany-wide traffic model Validate from PTV Transport Consult. We use this data to synthesize trucking profiles and calculate the most cost-effective technology for each of these profiles. Many other input parameters are included, such as route-specific consumption or a payload depending on the type of goods. When modeling fleet, time restrictions on the expansion of infrastructure and the availability of electric trucks on the market are also taken into account. In addition to the technology choice, the infrastructure requirements for the future truck fleet are a key result. The fleet and infrastructure (e.g. charging points, overhead line network) can be calculated on a geo-specific basis and thus provide indications of local traffic and infrastructure requirements for alternative drive technologies.
