In June 2005, Transport Secretary Alistair Darling announced a proposal for a national scheme [74] [75] in which every vehicle would be fitted with a satellite receiver that would calculate charges, with prices (including fuel duty) ranging from 2p per mile on uncongested roads to £1.34 on the most congested roads at peak times. [76]
This is a list of countries (or regions) by total road network size, both paved and unpaved.Also included is additional data on road network density and the length of each country or region's controlled-access highway network (also known as a motorway, expressway, freeway, etc.), designed for high vehicular traffic.
The pavement condition index (PCI) is a numerical index between 0 and 100, which is used to indicate the general condition of a pavement section.The PCI is widely used in transportation civil engineering [1] and asset management, and many municipalities use it to measure the performance of their road infrastructure and their levels of service.

The frequency of the suspension response at the golden-car simulation speed also determines the final IRI ride value. The IRI sensitivity is focused on wavelengths between 0.82 and nearly 200-feet (0.25 to 61 meters). Although, if any wavelengths are equal to 7.9 or 50 feet (2.4 or 15.2 meters) the IRI values are weighted higher. [2]
social costs (risk, noise, fumes) The operational requirements should be the following: related to the amount of use made of the roads; costs should vary according to the location, time, and type of vehicle; cities should be zoned, with costs raising to 10 shillings per hour of driving in the centre of London or Cambridge

A geometric design saved on construction costs and improved visibility with the intention to reduce the likelihood of traffic incidents. The geometric design of roads is the branch of highway engineering concerned with the positioning of the physical elements of the roadway according to standards and constraints. The basic objectives in ...
