Chapter 1 Introduction Definition of Traffic Engineering -- It is the phase of transportation engineering that deals with the planning, geometric design and traffic operations of roads, streets and highways, their networks, terminals, abutting lands, and relationships with other modes of transportation
Chapter 1. Introduction • Definition of Traffic Engineering --- It is the phase of transportation engineering that deals with the planning, geometric design and traffic operations of roads, streets and highways, their networks, terminals, abutting lands, and relationships with other modes of transportation
Transportation Engineering is defined as a discipline applying technology and scientifio principles to the planning, functional design, operation, and management of facilities for all modes of transportation Transportation mode includes: land, rail, water, air and pype. The focus of this class is on land transportation and connection with other modes
• Transportation Engineering is defined as a discipline applying technology and scientific principles to the planning, functional design, operation, and management of facilities for all modes of transportation. • Transportation mode includes: land, rail, water,air and pipe. • The focus of this class is on land transportation and connection with other modes
Scope of Traffic engineering -- surface (land) transportation: relationships and connection with other modes of transportation Share percentage among all modes with regard to people and goods Terminals, hubs and transfer center, port, storage logistics
• Scope of Traffic Engineering --- surface (land) transportation; relationships and connection with other modes of transportation • Share percentage among all modes with regard to people and goods • Terminals, hubs and transfer center, port, storage ---- logistics
Goal of Traffic Engineering -explore how to provide for the safe, rapid, comfortable, convenient, economical, and environmentally compatible movement of people and goods. Safe---public safety Rapid -- time value and customer service omfortable/convenient ---level of service Economical-- social cost Environmental --- clean air and sustainability Movement= mobility
• Goal of Traffic Engineering --- explore how to provide for the safe, rapid, comfortable, convenient, economical, and environmentally compatible movement of people and goods. • Safe --- public safety • Rapid --- time value and customer service • Comfortable/convenient --- level of service • Economical --- social cost • Environmental --- clean air and sustainability • Movement = mobility
Mobility versus Access -- with an increase of mobility the ability to access development decreases. and vise versa
• Mobility versus Access --- with an increase of mobility the ability to access development decreases, and vise versa
Hierarchy of highway classification Urban and suburban (rural) Criterion for roadway design Each country has different way in determining hierarchy of highways
