Fundamentals of Limited-Access Roads

A limited-access road is primarily designed for local traffic with frequent intersections and direct property access.

Answer: False

Explanation: The definition provided describes characteristics contrary to limited-access roads, which are designed for high-speed traffic with restricted access and grade-separated interchanges, not for local traffic with frequent intersections and direct property access.

Return to Game

Dual carriageways and grade-separated interchanges are features commonly found on limited-access roads.

Answer: True

Explanation: Limited-access roads are typically characterized by features such as dual carriageways to separate opposing traffic flows and grade-separated interchanges to manage traffic flow efficiently, distinguishing them from roads designed for local traffic.

Return to Game

Bicycles and horse-drawn vehicles are permitted on most limited-access roads to accommodate diverse traffic modes.

Answer: False

Explanation: Limited-access roads are designed for high-speed motor vehicle traffic and generally prohibit slow modes of transport, including bicycles and horse-drawn vehicles, to ensure safety and traffic flow efficiency.

Return to Game

What is the fundamental characteristic of a limited-access road?

Answer: Prioritizes high-speed traffic with limited or no direct property access and grade-separated interchanges.

Explanation: The fundamental characteristic of a limited-access road is its design to prioritize high-speed traffic flow by restricting or eliminating direct property access and utilizing grade-separated interchanges for entry and exit.

Return to Game

Which of the following is generally *prohibited* on limited-access roads?

Answer: Bicycles and horse-drawn vehicles.

Explanation: Limited-access roads are designed for efficient motor vehicle traffic and generally prohibit slow modes of transport, such as bicycles and horse-drawn vehicles, to maintain safety and speed.

Return to Game

What is the primary function of frontage roads in relation to limited-access roads?

Answer: They provide access to local properties and businesses without disrupting the main limited-access highway traffic.

Explanation: Frontage roads serve as crucial access routes for local properties and businesses, allowing them to connect to the road network without directly interrupting the flow of high-speed traffic on the adjacent limited-access highway.

Return to Game

What does the term 'stroad' represent in road design?

Answer: A road that combines characteristics of both a street (serving adjacent land uses) and a road (facilitating through traffic).

Explanation: The term 'stroad' describes a road that merges the functions of a street, providing access to adjacent land uses, with those of a road, facilitating through traffic. This hybrid nature often leads to conflicts between competing demands, unlike the separation of functions found in limited-access road design.

Return to Game

Which of the following best describes the role of frontage roads?

Answer: They provide access to local properties and businesses without disrupting the main limited-access highway traffic.

Explanation: Frontage roads serve to provide access to local properties and businesses, thereby preventing direct disruption to the high-speed traffic flow on the main limited-access highway.

Access Control Concepts

According to the US MUTCD, freeways are defined as divided highways with partial control of access.

Answer: False

Explanation: This statement is incorrect. According to the US MUTCD, freeways are defined as divided highways with *full* control of access, whereas expressways are defined as divided highways with *partial* control of access.

Return to Game

Full control of access means that entry and exit points are restricted exclusively to grade-separated interchanges.

Answer: True

Explanation: Full control of access, characteristic of freeways, signifies that all points of entry and exit are managed through grade-separated interchanges, thereby eliminating at-grade intersections and direct property access.

Return to Game

According to the US Manual on Uniform Traffic Control Devices (MUTCD), what distinguishes a freeway from an expressway?

Answer: Freeways have full control of access, while expressways have partial control.

Explanation: The US MUTCD defines freeways as divided highways with full control of access, meaning entry and exit are exclusively via grade-separated interchanges. Expressways are defined as divided highways with partial control of access, allowing for some at-grade intersections or direct property access.

Return to Game

What is the primary difference between partial and full control of access on US roads, according to the source?

Answer: Partial control allows some direct property access and at-grade intersections, while full control restricts access solely to grade-separated interchanges.

Explanation: The primary difference lies in the degree of restriction: partial control allows for some direct property access and at-grade intersections, whereas full control restricts all entry and exit points exclusively to grade-separated interchanges.

Historical Development

The United States saw its first limited-access roadways implemented in California in 1910.

Answer: False

Explanation: The initial implementation of limited-access roadways in the United States occurred earlier and in New York, not California in 1910. The Bronx River Parkway and Long Island Motor Parkway were established in 1907.

Return to Game

The Long Island Motor Parkway, established in 1907, is recognized as the first privately funded limited-access highway in the US.

Answer: True

Explanation: The Long Island Motor Parkway, established in 1907, is indeed recognized as the first privately funded limited-access highway in the United States, predating many public initiatives.

Return to Game

What historical event significantly impacted the planned upgrade of Santa Clara County's expressway system into freeways in the mid-1970s?

Answer: The rise of the tax revolt movement, including Proposition 13.

Explanation: The rise of the tax revolt movement in the mid-1970s, particularly exemplified by California's Proposition 13, significantly impacted the financial feasibility of upgrading Santa Clara County's expressway system into full freeways, leading to their retention with partial access control.

Return to Game

In which country were the first limited-access roadways, the Bronx River Parkway and Long Island Motor Parkway, implemented in 1907?

Answer: United States

Explanation: The Bronx River Parkway and the Long Island Motor Parkway, established in 1907, were among the earliest implementations of limited-access roadways in the United States.

Answer: True

Explanation: While terminology varies globally, 'expressway,' 'limited-access highway,' and 'partial controlled-access highway' are indeed commonly used terms that generally refer to roads with characteristics of limited access, though precise definitions can differ by jurisdiction.

Return to Game

In Australia, the terms 'expressway' and 'freeway' are always used to denote distinct levels of access control, with 'expressway' implying full control.

Answer: False

Explanation: The usage of 'expressway' and 'freeway' in Australia can vary regionally and may sometimes be used interchangeably or denote similar levels of access control, rather than strictly distinguishing them with 'expressway' always implying full control.

Return to Game

In New Zealand, 'Motorways' and 'Expressways' are legally identical, differing only in signage.

Answer: False
