Lecture 1.2 CEPC0203: Introduction to Highway & Railroad Engineering

Civil Engineering

• Specialization: Transportation Engineering
• Material Science: Concrete & Asphalt
• Fundamentals of Surveying
• Engineering Economics/ Cost Engineering

The Need for Highway & Railway Engineering - Economical

• Increase in Gross Domestic Product (GDP)

• More jobs in the construction, maintenance, and operation stage

• Attractive investment opportunities for both local and foreign

The Need for Highway & Railway Engineering - Political

• Better administration of projects/programs

The Need for Highway & Railway Engineering - Social

• More connected roads

• Efficient travel for commuters

• Lesser time of travel

• Better level of service (LOS)

The Need for Highway & Railway Engineering - Environmental

• “Greener” means of transportation

• Lesser carbon emissions for mass transportation

Modes of Transportation

• Land

• Water

• Air

• Pipe

Public Transportation - Mass Transit

• Fixed Route

• Fixed Schedules

Public Transportation - Paratransit

• buses, jeepneys

Public Transportation -Ridesharing

• angkas, grab

Road Transportation Characteristics

• Short distance travel must be less time consuming

• Dependent on weather

• Economical for government

• Complement other modes of transport

• Omnipresent

length of roadway a driver can see ahead at any particular time

Sight Distance

minimum sight distance required for a driver to stop a vehicle after seeing an object in the vehicle’s path without hitting that object;

Stopping Sight Distance (SSD)

distance required for a driver to detect an unexpected or otherwise difficult-to-perceive information source or hazard, recognize the hazard of its threat potential, select an appropriate speed and path, and initiate and complete the required safety maneuvers safely and efficiently;

Decision Sight Distance (DSD)

minimum sight distance required on a two-lane, two way highway that will permit a driver to complete a passing maneuver without colliding with an opposing vehicle and without cutting off the passed vehicle;

Passing Sight Distance (PSD)

Scope of Highway & Traffic Engineering

1. Planning

2. Design

3. Construction
