Final Answer:
Traveling on multiple-lane roadways is often faster than traveling on local roadways due to the reduced frequency of intersections, minimizing the need for frequent stops.
Step-by-step explanation:
The efficiency of travel on multiple-lane roadways compared to local roadways is influenced by the frequency of intersections and stops. On multiple-lane roadways, vehicles can maintain a more consistent speed for more extended periods, as there are typically fewer intersections that require stopping. This is particularly evident when comparing them to local roadways, where intersections and traffic signals are more frequent, leading to more frequent stops.
To illustrate, let's consider the time it takes for a vehicle to traverse a given distance on a multiple-lane roadway versus a local roadway. Assuming a vehicle travels at a constant speed on the multiple-lane roadway without any stops, the time taken can be calculated using the formula \( \text{Time} = \frac{\text{Distance}}{\text{Speed}} \). On the other hand, the time taken on a local roadway, considering the need to stop at intersections, will be longer due to the additional time required for deceleration, stopping, and subsequent acceleration. Therefore, the reduced frequency of stops on multiple-lane roadways contributes to faster travel times.
In conclusion, the assertion that traveling on multiple-lane roadways is often faster is based on the practical observation that reduced intersections lead to fewer stops, allowing for a more continuous flow of traffic. This results in a more efficient and faster travel experience compared to local roadways with higher intersection density.
