The formula for calculating RTI using a ramp as pictured above is r = d b × 1000 {\displaystyle r={\frac {d}{b}}\times 1000} Where b is the wheelbase of the vehicle, d is the distance travelled along a (usually 20 degree [ 1 ] ) ramp before any wheels leave the ground and r is the calculated ramp travel index.
All superlative indices produce similar results and are generally the favored formulas for calculating price indices. [14] A superlative index is defined technically as "an index that is exact for a flexible functional form that can provide a second-order approximation to other twice-differentiable functions around the same point."

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]
A cost estimator will typically use estimating software to estimate their bid price for a project, which will ultimately become part of a resulting construction contract. Some architects, engineers, construction managers, and others may also use cost estimating software to prepare cost estimates for purposes other than bidding such as budgeting ...
When you want to calculate gas costs, fuel efficiency, and the price of the tolls you will encounter during your road trip including any discounts available when using toll tags like EZ-Pass and ...
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 GEH formula is useful in situations such as the following: [4] [5] [6] Comparing a set of traffic volumes from manual traffic counts with a set of volumes done at the same locations using automation (e.g. a pneumatic tube traffic counter is used to check the total entering volumes at an intersection to affirm the work done by technicians doing a manual count of the turn volumes).
