Unfavourable weather conditions like heavy rain which may limit our data collection as there will be less pedestrians during these conditions.
Most people will not be available during working hours like at 9 am to 5 pm therefore our target respondents can potentially decrease.
Potential tripping hazards from pedestrian paths which can potentially injure data collectors.
No current availability of electronic devices (no signal, no device at the time, technologically challenged) which may limit their ability to answer their questionnaire.
See the weather forecast before initialising the investigation.
Choose a suitable time and date.
Walk carefully and wear comfortable footwear to avoid tripping.
Provide physical printed out form of the questionnaire for people who are unable to access the internet or their electronic devices.
