For reasons of comparability, the gradation is after the standard SN 640 017A "performance, traffic quality, resilience" for the MIV defined and otherwise made widespread six-level-of-service concept. At most, finer gradations are drafted for individual plant species in a first step, allowing a differentiated choice of the LOT limits, so that a subsequent adjustment of the boundaries is made possible in the context of intermodal consideration.

When drafting the correlations for assessing the performance and quality of traffic to the various systems of the light two-wheeled and pedestrian traffic four different methods are:

• Modelling of traffic flow for estimating relevant measurements and influence quantities
• Evaluation of previous findings (literature review)
• Empirical studies for calibration of existing guideline values for CH ratios and completing missing links
• Traffic simulations for completing missing links

The four methods are used differently depending on the scope of existing knowledge and according to the possibilities raised by the surveys and simulations for each type of plant.

For the quantification of parameters of pedestrian traffic the applicant may have recourse to various collection and simulation methods for recording / simulation of pedestrian flows due to reference projects. They differ with regard to the resources used, but also with regard to suitability for various traffic situations (type of system and traffic flow).

Based on the findings from the investigations described are to be developed for individual plant types recommendations for standardisation.
