Question by Lean: What is the significance of transportation engineering to civil engineering?

Best answer:

Answer by alpha b
*Transportation engineering is the application of technology and scientific principles to the planning, functional design, operation and management of facilities for any mode of transportation in order to provide for the safe, rapid, comfortable, convenient, economical, and environmentally compatible movement of people and goods (transport). It is a sub-discipline of civil engineering.

Transportation engineering is a major component of the civil engineering discipline. The importance of transportation engineering within the civil engineering profession can be judged by the number of divisions in ASCE (American Society of Civil Engineers) that are directly related to transportation. There are six such divisions (Aerospace; Air Transportation; Highway; Pipeline; Waterway, Port, Coastal and Ocean; and Urban Transportation) representing one-third of the total 18 technical divisions within the ASCE (1987)

Transportation engineering, as practiced by civil engineers, primarily involves planning, design, construction, maintenance, and operation of transportation facilities. The facilities support air, highway, railroad, pipeline, water, and even space transportation. The design aspects of transport engineering include the sizing of transportation facilities (how many lanes or how much capacity the facility has), determining the materials and thickness used in pavement designing the geometry (vertical and horizontal alignment) of the roadway (or track).

Before any planning occurs the Engineer must take what is known as an inventory of the area or if it is appropriate, the previous system in place. This inventory or database must include information on (1)population, (2)land use, (3)economic activity, (4)transportation facilities and services, (5)travel patterns and volumes, (6)laws and ordinances, (7)regional financial resources, (8)community values and expectations. These inventories help the engineer create business models to complete accurate forecasts of the future conditions of the systemReview.

Chevy (sorry GM) Volt does not count as an electric car because it uses gas

Question by Huh?: Lionel model railroad- Anything wrong here? history, science, transportation.?
Look at this Lionel item, and tell me if there is anything obviously and critically wrong with it.

Also, what might the welders be working on?

I’ll post my reasons after a few responses.

BTW. I’m asking in this category because there is no decent category for model railroading, and readers here seem to have good general knowledge.
BriaR has given all good answers, the way I saw it. However, I went back and enlarged the image twice size, and noticed that there is some liquid pouring from the top. Evidently the coal just happened to be there. I also see two welding gas tanks. I wonder if they are disconnecting the tank to make it easier to upright it, in two sections. Maybe this diorama isn’t as bad as I first thought. Thanks.

Answer by BriaR
Ha Ha Ha!! Good one!

1. Why are they carrying coal (or similar black granular solid) in a liquid tanker
2. The hazard triangles on the tanker plus the word “spirit” suggest a flammable liquid – so wtf is the guy doing with a welding torch?
3 If the force of the crash had been enough to rip of the top of the tank opening how come the tanker is undamaged
4 How did the coal manage to spill out in heaps higher than the outlet (assuming it could flow out at all
5 Why is the welder’s gas bottle so far from him with the pipe trailing over the tanker – why would they hump it over the spill?
6 Only 1 gas bottle – should be 2 one for the acetylene, one for the oxygen

Do I get a prize?

Are electric trains the best way for human transportation? And/Or why is it better than cars?

Tuesday, May 3rd, 2011

Question by YellowJeans: Are electric trains the best way for human transportation? And/Or why is it better than cars?
Please help. Thank you.

Answer by zzonyx
We’d first have to define “the best”. However, here are several certainties:
– trains consume much less energy per passenger than cars;
– trains have a much smaller CO2 footprint;
– trains need less space per passenger;
– train mile is cheaper than car mile per passenger.
On the other hand, trains can’t beat cars for flexibility and appeal. In a well-organized society there is ample space for both as they are complementary to each other.
