Final answer:
The characteristics mentioned, specifically the multilane highway with two lanes in each direction, a free-flow speed of 45 mph, and a peak-hour directional traffic flow of 1300, suggest a higher capacity and design that aligns more with an Interstate highway.
So, the most likely option is:
1) Interstate highway
The correct option is 1.
Step-by-step explanation:
The question is asking to identify the type of highway given the free-flow speed and peak-hour directional traffic flow characteristics.
To determine the type of the highway, we generally look at design standards, traffic volume, and speed limits, which usually vary for different types of highways. Interstate highways typically have higher free-flow speeds, often around 100 km/h (approximately 62 mph), and support larger traffic volumes than smaller state highways, county roads, or local streets.
The characteristics described in the question do not provide enough information to conclusively determine the specific type of highway categorically. However, it seems reasonable to exclude options such as local streets due to the higher traffic volume and free-flow speed mentioned.
To convert speed limits from kilometers per hour to miles per hour and from kilometers per hour to meters per second, we use the following conversion factors: 1 mile = 1.609 kilometers and 1 meter per second = 3.6 kilometers per hour.
Using these conversions: 100 km/h is approximately 62 mph because 100 km is about 62.1371 miles, and 100 km/h in meters per second is 27.78 m/s (since 100 km/h divided by 3.6 equals 27.78 m/s).
The correct option is 1.
