Compatibilidade das faixas de mudança de velocidade para o tráfego de veículos pesados em rodovias brasileiras

Abstract

An important device that must be considered in geometric design of high speed and heavy traffic roads are the speed-change lanes of these facilities. This parameter, besides improving road capacity, is responsible for the risk reduction of accidents as-sociated to their high-speed differential of vehicles sharing the same traffic lane, like rear-end collisions and overtaking in non-passing zones at intersections approaches. This paper presents an investigation considering traffic compatibility of heavy load vehicles, using acceleration and deceleration lanes, considering that the length requirements of these devices in the geometric design manuals are based on the performance of passenger cars.
