Question

In which category of the roads, parking can be least restricted?

• A. Arterial Roads
• B. Sub-arterial Roads
• C. Local and Access streets
• D. Collector Streets

Hint:

Remember the inverse relationship: \[ \text{Traffic Speed/Mobility} \propto \frac{1}{\text{Ease of Parking Access}} \] Because local and access streets have the lowest speeds and lowest mobility mandates, they naturally accommodate the highest allowance for on-street parking.

Answer 1

The Correct Option is C

Concept: Urban road networks are organized according to a clear functional hierarchy. This hierarchy balances two opposing transportation priorities: mobility (the speed and efficiency of through-traffic movement) versus accessibility (direct physical entry to adjacent land, properties, and storefronts). The functional hierarchy follows this general sequence: \[ \text{Arterial Roads} \longrightarrow \text{Sub-arterial Roads} \longrightarrow \text{Collector Streets} \longrightarrow \text{Local/Access Streets} \] As mobility increases, accessibility must decrease, meaning that parking regulations must become significantly tighter to prevent disruptions to high-speed traffic flows. Step-by-step Explanation:
• Arterial Roads: These high-capacity roads link major urban hubs and carry heavy volumes of fast-moving regional traffic. Because their primary goal is maximum mobility, roadside parking is strictly banned or heavily restricted to minimize friction, bottlenecking, and collision risks.
• Sub-arterial Roads: These assist arterial corridors by carrying traffic across large urban zones at slightly lower speeds. While they allow slightly more localized connections, curb-side parking remains highly restricted to maintain steady traffic velocities.
• Collector Streets: As the name implies, these collect traffic from local neighborhood streets and channel it to sub-arterial and arterial routes. They balance mobility and accessibility, meaning parking is regulated and permitted only within designated hours or bays.
• Local and Access Streets: These roads sit at the bottom of the mobility hierarchy but offer the highest level of direct property access. They are designed for low speeds within residential or quiet commercial zones. Because through-traffic is minimal and slow, curbside parking is least restricted here, often allowing residents and visitors to park freely along the street. Thus, Local and Access streets feature the lowest restrictions on parking.
