Travel Survey – Help the City of Cape Town Plan Public Transport

HELP THE CITY OF CAPE TOWN PLAN PUBLIC TRANSPORT SERVICES IN YOUR AREA – ALERT TO TRAVEL SURVEY FIELDWORKERS IN YOUR NEIGHBOURHOOD

Umtha Consultancy has been contracted by the City of Cape Town to conduct a Household Travel Survey, Trip Diary Survey, and Stated Preference Survey for Cape Town and Surrounding Towns.

The purpose of the survey is to collect updated demographic, travel behaviour, and employment information required to review and update the City’s MyCiTi and other public transport plans, to update the City’s strategic travel demand model, and to inform other future planning decisions and City processes. The information will be obtained through a regional household travel survey project that provides for the collection of accurate and current data, which is to be captured and converted to useful information through some elementary model estimation and data analysis.

This is a city-wide survey (including the surrounding towns), and we will be conducting house-to-house personal interviews in areas and individual households that have been selected in the randomised, systematic sampling process.

The fieldworkers will be identifiable by Umtha name tags with their names and City of Cape Town staff numbers.

We would be most grateful if you could assist the City with this important but challenging undertaking, and permit the fieldworkers to enter your property or community.

Please find below the details of the Project Manager from the City of Cape Town for confirmation.

FAQs

 

Why are you asking us all these questions?

The purpose of the survey is to collect updated demographic, travel behaviour, and employment information required to review and update the City’s MyCiTi and other public transport plans, to update the City’s strategic travel demand model, and to inform other future planning decisions and City processes. The information will be obtained through a regional household travel survey project that provides for the collection of accurate and current data, which is to be captured and converted to useful information through some elementary model estimation and data analysis.

This will include questions that help us understand peak travel and travel purposes, which is why we ask about the time and purpose of your travels.

Why can the City not conduct an online survey?

Because the City of Cape Town is unable to question every resident regarding their travel, the City is instead seeking data from a representative sample.

A sampling strategy has been drafted by a statistician from the University of Cape Town, and a particular number of responses per travel zone are required; these responses again need to be statistically representative, and reflect as little bias as possible. Where households selected through this randomized process refuse participation, substitutions are sought from within the same sampling frame in order to achieve the same representativity.

An online or electronic survey is not able to achieve this, as it will depend on self-selection and introduce substantive bias.

Why are you using cellphones to capture the data?

The Household and Travel Diary survey uses mobile electronic devices to capture the data which is then downloaded for quality assurance and analysis by a designated user with system administrator level access credentials.

The fieldworker will not need to type in extensive information, but will mark pre-populated fields.

The fieldworker might also ask you to indicate on his/her cell phone certain locational data.

The use of hand-held data capture devices with immediate upload to the cloud reduces the need for time-consuming data-capture and mitigates concerns with data-loss through theft of devices, for example. All of the locational data will be masked and will not be visible to anyone other than the City’s modelling team, and your name and other details are not linked to the survey.

Why are we surveying in the late afternoon and early evening?

Because the City of Cape Town needs to capture work-commute travel patterns, in order to plan for congestion mitigation measures.
