TRANSPORTATION ENGINEERING

• Transportation Engineering


  The specialized field of Civil Engineering that deals with the planning, geometric design and traffic operations.
• Modes of Transportation 


  Road, Rail, Air, and Maritime.
• Urban People Transportation System


  Automobile Taxi/For-Hire Vehicles, Public Utility Jeepney, Tricycle, Local Bus Transit, Light Rail, and Ferry.
• Intercity People Transportation System

  Automobile, Intercity Bus (point-to-point bus), Railroad, Air, and Water.
• Urban And Intercity Freight Transportation


  Long-Haul Trucks, Local Truck, Railroad, Air Freight, Water, and Pipelines.
• Relationship with General Public

  More than engineers and deals with a wide variety of public officials.
• Professional Ethics


  Has a great sense of responsibility based on the scale of the outcomes.
• Safety: The Primary Objective in Traffic Engineering

  Provision of a safe system for highway traffic.
• Safety: The Primary Objective in Traffic Engineering

  According to PSA, an average of 34 Filipinos dies every day. There's a daily average of 262 roads crashes in Metro Manila alone according to Assistant Secretary for DOTr, Mark de Leon.
• 53% - Motorcycle, 19% - Pedestrian, 14% - Drivers of cars etc., 11% - 4 wheeled vehicle passengers, 2% - Cyclists, and 1% - Others.
• In 2015, Motorcyclists tend to be most vulnerable, comprising 23% of all the road traffic death. Most accident-prone roads in Metro Manila: Alabang-Zapote Road, Commonwealth Avenue and EDSA.
• According to PSA on 2015, a number of 10,012 people die due to road crashes - a 45.76% increase from 6,868 deaths recorded in 2006.
• Objectives of The Traffic Engineer

  Speed - It is limited by transportation technology, human characteristics, and the need to provide safety.
• Objectives of The Traffic Engineer

  Comfort - Involves the physical characteristics of vehicles and roadways, and influence by our perception safety.
• Objectives of The Traffic Engineer

  Convenience - To ease with which trips are made and the ability of transport systems accommodate all of our travel needs at appropriate times.
• Objectives of The Traffic Engineer

  Economy - The economy is relative, with modern transportation systems being expensive due to massive construction, maintenance, and operating costs, but engineers are required to provide the best possible systems for the money.
• Objectives of The Traffic Engineer

  Environmental Compatibility - Environmental harmony is a complex issue, with all transportation systems contributing to negative impacts such as air and noise pollution and utilizing value land resources.
• Elements of Traffic Engineering

  Traffic studies and characteristics, Performance Evaluation, Facility Design, Traffic Control, Traffic Operations, Transportation System Management, Integration of Intelligent Transportation System Technologies.
• Challenges Traffic Engineers Face

  Change in notion from increasing capacity to meet demand to managing the movement of vehicle and people.
• Challenges Traffic Engineers Face

  Ever-increasing congestion.
• Challenges Traffic Engineers Face

  Safety and security of transportation facilities.
• Challenges Traffic Engineers Face

  Technically sound solutions may nor be socially acceptable.
• Challenges Traffic Engineers Face

  Traffic Engineering is still young as compared to other discipline, therefore, there leaves much to be desired.
• Possible Solution of Traffic Problem

  Facility Design: Add lanes, Remove bottlenecks, Revise geometrics to increase speed, Vehicle improvement to reduce highways.
• Possible Solution of Traffic Problem

  Traffic Control: Ramp Metering, Signal Coordination, Signal Phase Sequence, Left Turn Treatments, and Parking Restrictions.
• Possible Solution of Traffic Problem

  Reducing Demand: Telecommunicating, Trip Chaining, Shorter Work Week, Residential Relocation, Alternative Land use pattern.
• Possible Solution of Traffic Problem

  Shifting Demand: Flexible working hours, Staggered working hours, Business operating hours.
• Possible Solution of Traffic Problem

  Repacking Demand: Car Pooling and Van pooling, Transit.
