Sweden is a constitutional monarchy and a parliamentary democracy with a land area of 447,425 square kilometres (172,752 sq mi) and a population of 10.5 million people. In Sweden Sustainable Urban Mobility Plans (SUMPs) are essentially the same as strategies resulting from the Transport for an Attractive City (TRAST) handbook, published by Trafikverket. Transport strategies are generally linked to urban master plans. There is an increasing willingness and interest to develop sustainable transport strategies in Sweden, however, it is still not entirely normal practice to do this in all local authorities.
