Transportation as a System Engr. Carmela R. Mirandilla WHAT IS TRANSPORTATION ENGINEERING? 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. Highway Engineering is an art and science of planning, designing and constructing of roads and the maintenance and rehabilitation of finished roads. Why is transportation important in world development?  It links residences to employment It links producers of goods with their users It gives access to health, education and other amenities. →the desires of people to move and their need for goods create the demand for transportation. Can you state some more specific importance of transportation?  Nine Categories of Human Behaviour that are affected by Transportation 1.Locomotion 2.Activities 3.Feelings 4.Manipulation 5.Health and safety 6.Social interaction 7.Motivation 8.Learning 9.Perception  Locomotion (passengers, pedestrians) ability to move from place to place  Activities (vehicle control, maintenance, community life)  Feelings (comfort, convenience, enjoyment, stress, likes, dislikes)  Manipulation (modal choice, route selection, vehicle purchase) skillful control by something or someone  Health and Safety (accidents, disabilities, fatigue)  Social Interaction (privacy, territoriality, conflict, imitation)  Motivation (positive or aversive consequences)  Learning (operator training, driver education) Perception (images, mapping) Transportation systems can be evaluated in terms of three basic attributes: 1. ubiquity 2. mobility 3. efficiency  UBIQUITY the amount of accessibility of the system, directness of routing between access points, and the system’s flexibilty to handle a variety of traffic conditions  MOBILITY the quantity of travel that can be handled.  EFFICIENCY the relationship between the cost of transportation and the productivity of the system. Advanced Traffic Management System (ITS – Intelligent Transportation Systems)  Components of ITS 1. Smart Traffic signal control systems sense heavy traffic flows at road intersections and adjust the timing of signals automatically to accommodate the flows.  Components of ITS 2.Freeway management systems meter vehicles entering freeways with signals on on-ramps.  Components of ITS 3.Transit management systems help managers to control and monitor the movements of transit vehicles and adjust schedules accordingly.  4. Incident Management systems (IMS) detect and manage nonrecurrent traffic congestion caused by random unpredictable incidents, such as traffic accidents, lane blockages, and hazardous material spills resulting in major traffic congestion for considerable time periods. 5.Electronic toll collection on bridges and roads 6. Electronic fare payment systems 7. Emergency response allows emergency vehicles to control traffic lights at intersections. The emergency vehicle driver can hold the green phase until the intersection is cleared.  8. Travel information systems provide traffic information to users so that they can adjust their travel plans based on what they learn.  9. Route guidance system are based on Global Positioning System (GPS) Technology. It assists the motorists with distance and direction information to selected destinations. Thank you for listening my dear future Civil Engineers!
