What are the areas in Transportation Engineering, where Civil Engineer's service is required?
and mention three functions of each?
Solution
There are so many areas in Transportation Engineering where civil engineers are required. These
are mentioned below:-
1) Surveying:-
(i) surveys are conducted to find out a short route and most economical route for a new highway
project (ii) Levelling survey is carried out to estimate the quantity of cutting and filling work.
(iii) A good knowledge of surveying is needed when a curve is setting out on a road.
2) Planning & Design:
(i) Planning engineers determine and develop the most suitable and economical construction and
engineering methods for projects. (ii) The Responsibility of the planning engineer to estimate a
timescale for a project and to ensure that the outlined deadlines are met (iii) Design engineer
decides all the geometric parameters like sight distance, gradient, camber,road margins and
superelevation etc.
3) Site supervision:
(i) Site engineer ensures that construction work is being as per drawing. (ii) He checks all the
structural part that these are in proper dimension and form. (iii) He deals with all the technical
issues happening on site and provide his advice.
4) Highway maintenance:
(i) Maintenance of bridges, roads and tunnels ensures the safety of people and goods. (ii)A
highway maintenance engineer ensures that highways and roads stay in safe and working
condition (iii) A highway maintenance engineer must complete a variety of tasks on these
roadways including regular maintenance, snow and ice removal, creating dividing lines, and
fixing any defects in the road (such as potholes caused by wear and tear and extreme weather).
5) Quality control:
(i) There are various tests to be conducted to ensure quality of materials and soil with in
standards. (ii) Quality control lab is set up by civil engineer expert in various necessary tests. he
calibrates test apparatus time to time to ensure accuracy. (iii) Material made by third party is
checked and ensured for its quality and reliability.
6) Traffic engineering:
(i) Traffic engineers deals with the design and operation elements of roadways and the traffic
signs and signals that direct drivers. (ii) he studies situations to make sure stoplights or stop signs
are placed at the appropriate intersections, and he ensures that speed limits make sense for the
unique conditions of each roadway. (iii)They work on the design of new roads, highway and
expressways to maximize their capabilities handling the traffic expected to travel on them.
7) Railway engineering:
(i) Railway engineers deals with the design, construction, and operation of railways. (ii) they
perform some typical tasks like determining horizontal and vertical alignment design, station
location and design, construction cost estimating, and establishment of signalling & controlling
system (iii) They research for track modernization and speed enhancement techniques.
8) tunnel Construction:
(i) A tunnel can be for pedestrian or vehicular road traffic, for rail traffic, or for a canal.
(ii)Some tunnels are used as aqueducts to supply water for consumption or for hydroelectric
stations
(iii)Secret tunnels are built for military purposes
9) Airport Engineering:
(i) Airport Engineers deals with the the planning, design, and construction of terminals, runways,
and navigation aids to provide for passenger and freight service. (ii)Airport engineers design and
construct airports (iii)analysis of predominant wind direction to determine runway orientation,
determine the size of runway border and safety areas,

  • 1. What are the areas in Transportation Engineering, where Civil Engineer's service is required? and mention three functions of each? Solution There are so many areas in Transportation Engineering where civil engineers are required. These are mentioned below:- 1) Surveying:- (i) surveys are conducted to find out a short route and most economical route for a new highway project (ii) Levelling survey is carried out to estimate the quantity of cutting and filling work. (iii) A good knowledge of surveying is needed when a curve is setting out on a road. 2) Planning & Design: (i) Planning engineers determine and develop the most suitable and economical construction and engineering methods for projects. (ii) The Responsibility of the planning engineer to estimate a timescale for a project and to ensure that the outlined deadlines are met (iii) Design engineer decides all the geometric parameters like sight distance, gradient, camber,road margins and superelevation etc. 3) Site supervision: (i) Site engineer ensures that construction work is being as per drawing. (ii) He checks all the structural part that these are in proper dimension and form. (iii) He deals with all the technical issues happening on site and provide his advice. 4) Highway maintenance: (i) Maintenance of bridges, roads and tunnels ensures the safety of people and goods. (ii)A highway maintenance engineer ensures that highways and roads stay in safe and working condition (iii) A highway maintenance engineer must complete a variety of tasks on these roadways including regular maintenance, snow and ice removal, creating dividing lines, and fixing any defects in the road (such as potholes caused by wear and tear and extreme weather). 5) Quality control: (i) There are various tests to be conducted to ensure quality of materials and soil with in standards. (ii) Quality control lab is set up by civil engineer expert in various necessary tests. he calibrates test apparatus time to time to ensure accuracy. (iii) Material made by third party is checked and ensured for its quality and reliability. 6) Traffic engineering: (i) Traffic engineers deals with the design and operation elements of roadways and the traffic

(ii) he studies situations to make sure stoplights or stop signs are placed at the appropriate intersections, and he ensures that speed limits make sense for the unique conditions of each roadway. (iii)They work on the design of new roads, highway and expressways to maximize their capabilities handling the traffic expected to travel on them. 7) Railway engineering: (i) Railway engineers deals with the design, construction, and operation of railways. (ii) they perform some typical tasks like determining horizontal and vertical alignment design, station location and design, construction cost estimating, and establishment of signalling & controlling system (iii) They research for track modernization and speed enhancement techniques. 8) tunnel Construction: (i) A tunnel can be for pedestrian or vehicular road traffic, for rail traffic, or for a canal. (ii)Some tunnels are used as aqueducts to supply water for consumption or for hydroelectric stations (iii)Secret tunnels are built for military purposes 9) Airport Engineering: (i) Airport Engineers deals with the the planning, design, and construction of terminals, runways, and navigation aids to provide for passenger and freight service. (ii)Airport engineers design and construct airports (iii)analysis of predominant wind direction to determine runway orientation, determine the size of runway border and safety areas,
