Felhajtóút

A felhajtóút is a Hungarian term that translates to "on-ramp" or "access road" in English, specifically referring to a road that connects a local or regional road to a higher-speed road, most commonly a motorway or expressway. These structures are essential components of modern road networks, facilitating the smooth and safe integration of traffic from lower-speed arteries onto faster-moving thoroughfares.

The primary function of a felhajtóút is to allow vehicles to gradually increase their speed to match the traffic flow on the main road. This is typically achieved through a sloped section of road designed to accommodate acceleration. Conversely, when exiting a motorway or expressway, a corresponding "lehajtóút" (off-ramp) allows vehicles to decelerate safely before merging with local traffic.

Felhajtóút designs vary, but often include acceleration lanes that provide sufficient distance for drivers to reach the appropriate speed. Safety considerations are paramount in their construction, with features such as clear signage, appropriate banking on curves, and sometimes median barriers to prevent accidents. They are a critical element in managing traffic flow and preventing congestion, especially in areas with high volumes of intercity or long-distance travel. The presence of felhajtóút is a defining characteristic of a well-developed road infrastructure.
