Transportation Economics - An Introduction -Transportation-engineering

Transportation economics an introduction - Transportation engineering Transportation economics studies the economic side of the larger subject of traveling. Costs of providing and using different modes of transport are weighed, in terms of money, time, and environmental impact. To learn more on transportation economics some basic knowledge is very essential which has....

CBR test and its procedure - California Bearing Ratio

CBR test and its procedure - California Bearing Ratio California bearing ratio test was developed by California state highway dept for evaluating strength of subgrade & other pavement material. Flexible pavement thickness is determined based on this test. It may be conducted in the laboratory or in the field as well. IS 2720-16 is the IS code used for....

Origin and destination studies - Traffic Engineering

Origin and destination studies - Traffic Engineering The origin and destination studies show the amount of travel (in terms of traffic, time taken etc.,) existing between certain destinations that are in consideration (as origin and destination). Origin and destination studies give information on the actual location or zone of origin of travel of vehi...

Traffic volume studies and speed studies - Traffic Engineering Traffic studies are basically made to analyse the characteristics of traffic. the basic objectives of traffic studies includes to obtain knowledge of type and volume of traffic at present and future &to study the road facilities and improvements to be done & to design geometric features and payment....

Public transport - Comparision of metro vs mono rail vs tram buses....

Public transport - Comparision of Metro vs Mono rail vs Tram & Bus There exists various modes of public transport within a city. Buses are most widely used mode of public transport in India. Metro are being popularized in recent decades across various Indian cities, mono rail exists in only few cities. Here is detailed comparison of various transport services like....

Factors affecting compaction of soil - Geotechnical Engineering

Factors affecting compaction of soil - Geotechnical Engineering Soil compaction is very important thing in construction activity. Loose and uncompacted soil with voids in them tend to settle under load, hence compaction of soil is very important. The factors affecting soil compaction are discussed below, there are various factors out of which some important fact...

Laboratory tests done to find total solids, dissolved solids & suspended solids

Tests to find Total solids | Suspended solids | Dissolved solid in water Solids are measured by gravimetry method. Classification of solids in water includes total solids, total suspended solids, and total dissolved solids. Total dissolved solids includes the dissolved solids plus the colloidal solids. The process of measuring these solids is described here.

Turbidity of water and its measurment – Environmental engineering

Turbidity of water and its measurment - Environmental engineering The suspended and colloidal particles offers resistance to the light rays passing through the water that is the opaqueness in water reduces because of the presence of suspended and colloidal particles and this is called as turbidity of water. NTU, JTU, FTU are the common units of turbidity measurmen...

Indian road & its classification NH SH MDR ODR VR

Indian road & its classification NH SH MDR ODR VR - CIVIL ENGINEERS The roads or the highways are of national importance. In-fact whenever we talk of infrastructure development, we mainly consider the development of the highways. National highways and expressways are top class roads in India. For proper analysis of highways, their classification into various types i...

Airport Runway design and wind rose diagram

Airport Runway design and wind rose diagram - CIVIL ENGINEERS Runway design using wind rose diagram is essentially determining the direction (or the alignment) and the length of the runway. Runway is the key thing in an airport essentially a strip of land where the airport lands and takes off. Runway must be essentially strong to contain the fast approaching c...

GRADIENT AND GRADE COMPENSATION OF RAILWAY TRACKS- GEOMETRIC DESIGN OF RAILWAY TRACK

Gradient and grade compensation of railway track - CIVIL ENGINEERS The gradient of the railway track is usually measured by either the extent of rise/ fall in 100 units of horizontal distance. Types of gradients in railway Ruling gradient, Momentum gradient, Pusher or helper gradient, gradient at station yard. Grade compensation on curves is reducing the gradients....
