What is Historical Background of a Freeway?
The historical background of the freeway begins in the early 20th century. Prior to that, the roads were unpaved and inadequate for the growing transportation needs. The demand for high-speed roads leads to the concept of a freeways and parkways in the USA. This idea meant making come into existence roads (freeways) separated from local streets for automobile transport.
There is an important of German Autobahn in the development of freeways. The Autobahn was built on a model of high speed, limited access and limited entry points. Due to the success of the Autobahn, comparable roads were built in other nations.
Freeways’ Emergence and Purpose
Freeways started to arise in different places of the world to meet various transportation challenges. Here is a description of the development of a highway and its goals:
Traffic Congestion:
Traffic congestion increased after increasing automobiles on the roads. Traffic congestion was causing traffic jams and safety concerns in the urban areas especially.
Need for Efficient Travel:
The freeway was designed to meet the needs of fast travel for transportation. In which the local traffic was separated from a freeway. Specific locations were designed to access a freeway. Pedestrian crossings, intersections and traffic signals were also removed. Reduced travel time and increased safety are the main goals of freeway construction.
Economic Development and Trade:
A freeway improves the connections between cities and states. It also eases the delivery of goods and services which increase trade and economic development of a country. In the present time, a freeway has become a back bone for inexpensive transportation of products. For the effective transfer of goods and services, a freeway is now required. This road also lowers the product’s price of transportation to the market.
Tourism and Travel:
Thanks to freeways, it is very easy to access the famous places, natural routes and entertainment places now. A freeway is also playing an import role in the promotion of tourism in any country.
Specifications of a Freeway Road
High Speed Road:
Freeway is a high speed roadway. Traffic can travel at a high speed without any collision on this roadway. The speed limit on freeways is higher as compared to other roads. Which is about fifty five to seventy five miles per hour. This speed limit may be even more in some areas depending upon the size and requirements.
Controlled Access and Limited Entry Points:
The freeways have entrances and exits at specific points called on ramps and off ramps. Vehicles can enter and exit the freeway road at these points. Such roadway characteristics like controlled access and fewer entry sites help in maintaining the traffic flow.
The design and implementation of controlled access and limited entry points in different countries may vary depending on traffic conditions and available resources. However, traffic volume, safety considerations and transportation needs are taken into consideration while planning a freeway.
Divided Roadways and Multiple Lanes:
On the freeway, clear separation is provided in the flow of traffic with the help of a median to prevent the collision of vehicles. In the urban areas a freeway has three or more lanes in each direction. While in less congested areas there are 2 or 3 lanes. Lane markings on freeways guide drivers ensure safety and smooth traffic flow.
Absence of at-Grade Crossings and Traffic Lights:
One of the advantages of freeways is that this roadway is grade crossings free and traffic signals free. Actually, freeways are designed for transportation of a large volume of vehicles. The underpasses and overpasses in the design of a freeway eliminate the need for grade crossings and traffic signals on this roadway. Since there are no grade crossings or traffic lights on freeways, traffic moves more smoothly, safely, and efficiently without any congestion.
What advantages and benefits a freeway give you?
Freeway is a road equipped with safe and high speed travel facilities. In parts of world, this roadway is also referred to as highway, expressway, or motorway. Some of the main objectives and benefits of freeway are as follows.
Efficient Transportation:
Multiple lanes, controlled access points, and limited intersections are added in the design of a freeway. Therefore, the maximum number of passenger and commercial vehicles can travel on it without causing any congestion.
Safety:
The freeway has been designed keeping in mind the safety of passengers. It has separate tracks for vehicles traveling in the opposite directions. Due to which there is no risk of head on collision of vehicles. In the same way, controlled access points, ramps and interchanges are built on a freeway to reduce the risk of collisions from the rear and sides of vehicles.
Freeway Reduces Travel Time:
A freeway provides fast and safe travel compared to normal roadways. It is due to the lack of traffic signals and intersections. The vehicles traveling for a long distance can also reach their destination quickly on this roadway.
Economic Benefits:
A freeway plays an important role in accelerating the economic growth and development of any country. Due to this, regional connections are also promoted. Due to the freeway, it becomes easier for people to reach their destination, access educational institutions and visit tourist areas.
Freeway Enhance the Regional Connectivity:
Freeways connect towns, cities and states by providing seamless transportation between different regions. It promotes regional connectivity by facilitating the exchange of goods, services and ideas. This connectivity between urban and rural areas promotes economic development, tourism and cultural exchange.
Design Features of a Freeway
The primary feature of a freeway is to ensure efficient and safe movement of vehicles, goods and services. Here are some common design features of a freeway:
Grad Separation:
The grade separation is an important feature of freeway design. It means raising or lowering the freeway road to eliminate intersections, cross traffic, and other obstacles. This design feature helps reduce the risk of accidents and maintain smooth flow of traffic.
Wide and Multiple Lanes:
A freeway has multiple lanes in each direction which facilitates the efficient flow of traffic. The width and number of lanes may vary depending on the volume and traffic needs of different freeways. The multiple lanes helps to adjust the speed, overtake, and merging of vehicles.
Limited Intersections:
A freeway has limited intersections unlike ordinary highways, to reduce the risk of conflict and maintain the efficient flow of traffic. Intersections are typically avoided, and if necessary, these are controlled using overpasses and underpasses.
Emergency Lanes:
A freeway usually has emergency lanes, also known as breakdown lanes or hard shoulder. Which are designated areas for vehicles to pull over in case of emergencies or vehicle breakdown:
Driving Without Traffic Signals:
As we know the traffic signals are used to control the flow of traffic to reduce collisions on the roads and streets. One of the benefits of traveling on a freeway is the absence of traffic signals while driving. The traffic can travel at high speed without traffic signals and stopping. Therefore, on a freeway, traffic management techniques like overpasses, underpasses, on and off ramps, and interchanges are used to serve the purpose of smooth flow of traffic. Which provide the drivers complete information about the driving condition on the roadway.
Safety considerations on freeways
Advanced Signage and Markings:
To guide drivers, there are clear and consistent signage and markings on a freeway. These signage and markings provide warnings, indicates exits and other important information to the drivers. This advance signage and marking system helps drivers to make informed decisions while driving and navigate the freeway safely.
Emergency Lanes and Facilities:
A freeway typically has emergency lanes, which are known as breakdown lanes or hard shoulders. Vehicles can pull over in case of emergency or breakdown on these lanes. These lanes provide a safer space for vehicles to stop and as well as emergency services to respond.
Lighting and Visibility:
The freeway is well lit at night and also in bad weather conditions to improve visibility of drivers. Enough lighting reduces the risk of accidents by improving driver awareness.
