Abstract
  • In response to the growing environmental concern and higher operating cost of regular automobile, the concept of Low-Speed Vehicles (LSVs) is becoming popular as a sustainable mode of transportation. Primarily designed for protected environments and gated communities, the use of these vehicles is gradually increasing on public roadways as a short-range alternative to fossil-fueled autos. LSVs have a maximum speed limit of 25 miles per hour and these vehicles are not subject to the same federal requirements for occupant protection as regular passenger cars. This research investigated the safety standards and operating regulations pertaining to LSVs across the U.S. The finding of this study emphasizes the need for a LSV-friendly infrastructure in order to accommodate LSVs on the existing roadway system which is typically designed for larger and faster moving vehicles. However, development of a completely new LSV infrastructure and/or modification of the existing road network to accommodate LSVs would be very expensive, time consuming and in many cases, not feasible due to adjacent land use characteristics. Considering these issues, this research proposes a comprehensive planning methodology to develop a secondary low speed roadway network that can be applied to a small or medium-sized city with geographically compact activity spaces. The secondary roadway network would provide safe and efficient connectivity from residential neighborhoods to all major activity centers of the city by both human and non-human powered low speed vehicles, while minimally affecting the road safety and traffic operations of regular automobiles, or exposing the LSV operators to undue risk.
