An object that represents a travel mode. Travel modes on a network dataset define how a pedestrian, car, truck, or other medium of transportation moves through the network. A travel mode consists of a collection of network dataset settings that define actions that are allowed on the network and how the actions can be performed. Selecting a predefined travel mode allows you to efficiently and consistently set a number of properties that are appropriate for the mode of travel you intend to model. Since a travel mode is a collection of properties that work together it is recommended to have a full understanding of how these properties interact before altering them on the fly for a particular analysis. A best practice would be to create a new travel mode in the network dataset in ArcGIS Desktop or ArcGIS Pro that is fully tested to ensure that is returns the required solution.
Attribute parameter values. The attribute parameter values e.g. Vehicle Weight, Vehicle Height, etc. Attribute parameter values are useful for customizing individual restrictions ("Don't travel on a roads weight limits below 6 tons").
