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, also known as highways or freeways, are designed to handle large volumes of traffic efficiently and safely. One of the primary advantages of driving on expressways compared to two-lane roads is their ability to support higher traffic volume. This is due to several key design features of expressways that distinguish them from regular roads.
Firstly, expressways are typically wider and have multiple lanes in each direction, which helps to accommodate more vehicles. This is crucial in areas with high traffic demand, as it reduces congestion and delays. Additionally, expressways are designed with fewer intersections and access points, which helps to maintain a smoother flow of traffic. This is in contrast to two-lane roads, where frequent intersections, traffic signals, and turns can create bottlenecks.
Furthermore, expressways are built to allow higher speed limits, which helps in efficiently moving traffic over longer distances. The design also minimizes the risk of collisions, as expressways often feature median barriers or other physical separations between opposing lanes of traffic. This safety feature is especially important in reducing the chances of head-on accidents.
Unlike two-lane roads, which may have mixed traffic (pedestrians, bicycles, and slower-moving vehicles), expressways are typically restricted to motor vehicles only, further enhancing traffic flow. Pedestrians and bicyclists are generally not allowed on expressways, as they can present significant hazards to both themselves and drivers.
In conclusion, expressways offer a more efficient and safer driving experience, primarily due to their design that supports higher traffic volumes and reduces the potential for accidents or delays. This makes them a preferred choice for long-distance travel and areas with high traffic congestion.
