Table 2

Explanations and key references of the four main influencing factors of congestion pricing.

Factor	Definition	Literature cited (related)
Factor of fairness	Two elements make up the issue of equity in congestion pricing: the tolling strategies and the distribution of tolls among various sociodemographic groups.	[56, 57, 67, 69–73]
Personal privacy	The core opposition cause of congestion pricing is privacy, since the client’s private information recorded may be deemed an invasion of travellers’ privacy.	[5, 19, 49, 66, 71, 72, 74, 75]
Increasing of risk	Though the electorates are well versed on matters status quo, they are not certain or well versed with the proposed congestion pricing regarding revenue allocation and effectiveness.	[4–6, 22, 57, 63, 64, 73, 76, 77]
Difficulty of implementation	To settle an efficient and clear hypothetical charging scheme that is conveniently understandable and useful for road’s users and the public in general.	[61, 65–68, 75, 77–79]
