OSM road networks are currently used in analysis because the road network shapefiles are not available in node and link table format. If the road network shapefile can be converted to this format, then these can be used in the analysis. The node table should be a dataframe with the columns: node_id, longitude and latitude. The link table should be a dataframe with (at minimum) the columns from_node_id, to_node_id, length, max_speed.
Alternatively, please review the OpenStreepMap network data for HCMC and confirm if it is accurate enough for the models.
