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, works, terminals, abutting lands, and relationships with other modes of transportation.
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
Goal of Traffic Engineering --- explore how to provide for the safe, rapid, comfortable, convenient, economical, and patible movement of people and goods.
Safe --- public safety
Rapid --- time value and customer fortable/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.
Urban and suburban (rural)
Criterion for roadway design
Each country has different way in determining hierarchy of highways
Hierarchy of highway classification
Roadways
