Figure 2-5: Diagram which illustrates the transportation planning cycle which included in the elements of transportion
planning
The elements of transportion planning :

Inventory
 include the establishment of the data for the evaluation of the existing travel demand and
existing travel capacity
 Will involve 2 main task which is collecting and processing data.

Land uses
 Required a detailed assessment and forecasting in terms of distribution of area, population,
employment, economic, social and land use activities.

Trip generation
 The first model of travel demand used in transportation planning process.
 Used to predict which zone the traffic will flow.

Trip Distribution
 The second model travel demand used in transportation planning process.
 To get a travel/traffic pattern (in/out) in a zone
 Shows the total traffic in certain time, distance and cost

Modal Split
 To estimate the number of trips by different types of transport
 Limited to public and private transport only

Traffic Assignment
 Intended to give a traffic direction to which road in road/transport network.

Assessment
 Contains the testing and evaluation of the alternatives selected before.
 emphasis on the ability of the traffic and environmental impact of each alternative strategy
 to choose and determine the best transportation system for future needs
