Roads and Highways

Roads and Highways

Road is a route, public thoroughfare or way that supports travel by a means of conveyance.

Roads and highways are defined as strips of land that have been cleared and further improved for the transportation of people and goods

Highway First used in England to describe a

public road built by digging ditches on both sides and heaping up the earth in the middle creating a way higher than the adjacent land

A higher state of development than road

Arterial Highway Highway primarily for through traffic,

usually on a continuous route Control of Access

A condition where the right of owner of abutting land or other person to access right of view in connection with highway is fully or partially controlled by public authority

Full Control of Access: is excercised to give preference to through traffic by providing access connections to selected public roads only. Crossing at grade or direct private driveway connections is not permitted.

Partial Control of Access: it is excercised to give preference to through traffic. Although in addition to access connections with selected public roads, there may be some private driveway connections allowed.

Control of Access

Expressway : Divided arterial highway for through traffic with full or partial control of access and generally with grade separations at major intersections

Freeway: is an expressway with full control of access.

TYPES OF HIGHWAYS

Expressway

Freeway

An arterial highway for noncommercial traffic with full or partial control of access and usually located within a park or park-like development

A broad landscaped highway, often divided by a planted median strip.

Parkway

Parkway

Through Highway Every highway or portion thereof on

which traffic is given right of way, and at the entrances to which traffic from intersecting highways is required by law to yield right of way to vehicles on such through highway in obedience to either a stop sign or a yield sign

Through Street

Through street

An arterial route that carries traffic to the nearest access point or through traffic. It often serves as the most advantegous routes for relatively long distance travel.

It is considered as a “make do” substitute for controlled access facilities when traffic volume exceeds about 20,000 vehicles per day.

Arterial Street

1. Parking is prohibited on one or both sides of the street

2. Parking is prohibited several meters away from each side of the road intersections or corners

3. Right turn is allowed on red signals any time with care

4. Left turns are eliminated on congested intersections

5. The direction of traffic is reversed in the center lane to provide more lanes in the direction of heavier traffic flow

Solutions to consider in increasing the capacity of arterial highway during peak hour traffic volume:

Form smaller mesh grid pattern where passengers are pick up from service streets and carried to the arterials

Large commercial enterprises or amusement facilities

Collector Street

Street or road mainly for access to residence, business, or other abutting/adjoining properties.

Road constructed and maintained by the local government Frontage Street Cul-de-sac Dead-end-road

Local Road

Divided Highways: Highways which lanes going in the Opposite directions divided by a median or some sort of barrier between them.

County Road: A county road is a road that is regulated an maintained by a certain country.

State Highway: This is a highway that is administrated by the state

Other Types of Highways

Interstate Highways: These were the Highways that were created by Dwight D. Eisenhower in the 50s. These are expressways that criss-cross the country that carry large volumes of traffic.
