Chapter 13 describes the development of ‘travel time distribution’ values for New Zealand using data from the Ministry of Transport’s New Zealand Household Travel Survey (NZHTS). It includes a brief overview of the NZHTS, the methodology used to develop origin–destination (OD) trip matrices, a description of the travel time distribution parameters and how they were identified, and a summary of the deterrence parameters that were calculated. It also makes a brief comparison with results from the UK.
Chapter 14 outlines the steps involved in the creation of the four network datasets; namely the walking, cycling, public transport and private vehicle datasets.
Chapter 15 details each of the seven steps in the accessibility calculation methodology. It begins with a description of the process required to prepare the input datasets for the accessibility calculation. Two distinct phases of the methodology are then discussed. The first phase involves performing the shortest path network calculations for each activity across each of the four networks. The second phase involves combining the results of the network calculations using a weighting matrix to create comprehensive accessibility scores across a study area.
Chapter 16 applies the accessibility calculation methodology, in a case study of the city of Christchurch, New Zealand. Comprehensive accessibility scores were calculated across the city at a meshblock level to provide a baseline dataset. Two scenarios, the construction of a new hospital in Halswell and the construction of a bridge across the mouth of the Avon–Heathcote Estuary were then modelled and the results compared to the baseline dataset in order to quantify the accessibility gains from these two scenarios.
Chapter 17 presents a discussion of the methodology. It examines how to interpret the outputs of the accessibility calculations and proposes some applications which have been made possible due to the development of this accessibility methodology.
Chapter 18 concludes the report drawing together the ideas presented throughout the report.
Chapter 19 includes areas of further research and recommends the next stages of work to develop and refine the accessibility methodology and accessibility planning programme.
Chapter 20 includes the technical references used to inform this research
