1. Define the concept of trip generation, and discuss why it is important in transport modelling.

Trip generation is a concept that predicts the number of trips that originate or are destined in a given traffic analysis zone.   Through trip generation model, it is easy to predict the total traffic in a given traffic analysis zone. It operates on the basic concept that every trip has two ends and knowing where the two ends are is important in predicting traffic (Ortuzar & Willumsen 2001). Trip generation analysis focusses on residences. It is a function of social and economic attributes at the household level. It is therefore used to forecast travel demands in a given area.




Overall Assignment Aim:


In this assignment, you are required to provide definitions to key transport planning concepts and terms, and

demonstrate their application. The aim of this assignment is to develop your knowledge of transport planning concepts and terms in order to provide you with confidence to solve transport planning problems.

Please answer all questions.

  1. Define the concept of trip generation, and discuss why it is important in transport modelling.
  2. Define the terms ‘trip origin’ and ‘trip destination’ in terms of how that are used to define the concept of a trip. Why is it important in transport modelling to characterize trips in terms of their origins and destinations?
  3. Define and discuss the importance of the concept of modal choice in modelling trip activities.
  4. What is ‘route assignment’, and why is it important in modelling a transport network?
  5. Why is analyzing the ‘trip-rate’ important for different types of land uses?
  6. Why is it important to analyze peak trip flows in a transport network when modelling the demand for travel?
  7. Select one travel mode, and rate its environmental, economic, social, health and safety advantages as high, medium or low, briefly providing key evidence to support each of your claims.
  8. Why is travel behaviour important to analyze when investigating trip flows in a transport network? Discuss the characteristics of travel behaviour that would be of interest in undertaking an analysis of trip flows.
  9. Define the concept ‘autonomous vehicles’ (AVs), and discuss the key urban transport implications for urban travel if AVs were to replace conventional motor vehicles.
  10. The concept ‘Level of Service’ is used to assess the performance of transport networks (typically involving either motor vehicle traffic, pedestrians or cyclists). Discuss how this concept affects the capacity of a transport network and why it is an important transport planning consideration.
