There are numerous advantages to expressway driving over two-lane roads. One of those advantages is:
a) Supports higher traffic volume
b) Allowing intersecting traffic
c) Pedestrians and bicyclists are allowed to travel on expressways
d) Supports less traffic
The correct answer and explanation is:
The correct answer is a) Supports higher traffic volume.
Expressways are designed to accommodate a larger volume of vehicles compared to two-lane roads. One of the primary advantages of expressway driving is that they can handle significantly more traffic due to their wide lanes, multiple lanes in each direction, and often, the absence of intersections or direct access points. These factors allow vehicles to travel at higher speeds, reducing congestion and facilitating smoother traffic flow.
In contrast, two-lane roads have limited capacity and tend to become congested more easily, especially when vehicles need to stop or slow down for turns, traffic lights, or intersections. Expressways, on the other hand, usually have controlled access points, meaning vehicles can enter and exit through ramps and overpasses instead of having to stop at intersections. This system helps maintain a consistent flow of traffic without frequent disruptions.
Moreover, expressways are often designed with features like higher speed limits, dedicated lanes for trucks or buses, and fewer intersections. These features further enhance their ability to handle large amounts of traffic. This increased capacity is especially important in urban and suburban areas where population density and vehicle numbers are high.
In addition to supporting higher traffic volume, expressways also typically have other safety features like barriers, medians, and lighting, all of which contribute to reducing accidents and increasing overall traffic efficiency. The combination of all these factors makes expressways the preferred choice for long-distance travel and for handling larger traffic volumes compared to two-lane roads, which have more frequent stops and a higher likelihood of congestion.
