This research seeks to measure citizen satisfaction with the electronic London Congestion Charging (LCC)
payment system offered by Transport For London (TFL) in the United Kingdom (UK). The paper reports
on the findings of a survey of 500 users of the TFL LCC online payment system. Satisfaction is measured
using the four dimensions from the COBRA framework 0that comprise the cost, opportunity, benefits and
risk assessment constructs. The results show that most citizens using the LCC electronic service are
satisfied with the service and that the service meets their essential needs. The paper also presents the
results of qualitative feedback obtained from the participants that can be used to determine the areas that
need further improvement in the current electronic LCC electronic-service (e-service) system and
potential influences on user satisfaction
