Traffic barrier with a pedestrian guardrail behind it. Traffic barriers (known in North America as guardrails or guard rails, [1] in Britain as crash barriers, [2] and in auto racing as Armco barriers [3]) keep vehicles within their roadway and prevent them from colliding with dangerous obstacles such as boulders, sign supports, trees, bridge abutments, buildings, walls, and large storm drains ...
The barrier effect of roads and highways is a phenomenon usually associated with landscape ecology, referring to the barrier that linear infrastructure like roads or railways place on the movement of animals.
Filtered permeability requires cyclists, pedestrians (and sometimes public transport) to be separated from private motor vehicles in some places, although it can be combined with shared space, elsewhere in the same town or city. This is the case in Dutch towns such as Drachten.
Water transportation is the slowest form of transportation in the movement of goods and people. Strategic chokepoints around the world have continued to play significant roles in maritime industry. Although the slowest form of transportation compared to road and rail transport, it is the most cost effective. [citation needed]
Indian giant squirrel, a tree dweller, killed on a road that has disrupted the rainforest canopy. Roads can act as barriers or filters to animal movement and lead to habitat fragmentation. [42] Many species will not cross the open space created by a road due to the threat of predation [43] and roads also cause increased animal mortality from ...
Road transport or road transportation is a type of transport using roads. [1] Transport on roads can be roughly grouped into the transportation of goods and transportation of people. In many countries licensing requirements and safety regulations ensure a separation of the two industries.
A modal filter, sometimes referred to as a point closure, [1] is a road design that restricts the passage of certain types of vehicle in road transport. Modal filtering is often used to help create a low traffic neighbourhood (LTN), where motor traffic is diverted away from residential streets [2] [3] and instead toward feeder roads.
Highway engineering (also known as roadway engineering and street engineering) is a professional engineering discipline branching from the civil engineering subdiscipline of transportation engineering that involves the planning, design, construction, operation, and maintenance of roads, highways, streets, bridges, and tunnels to ensure safe and effective transportation of people and goods.
