This paper describes the utilization of park-and-ride (PNR) lots in South East Queensland (SEQ). In the literature, utilization of PNR lots is generally taken as a static property. We consider utilization as a dynamic property of PNR lots and hence study utilization by conducting a survey of PNR lots for a period of time during a weekday morning. From the survey we collected data on the number of car arrivals and their arrival time. Utilization is measured as the ratio of usage (number of cars parked) of the PNR lot to its capacity. Also, information on the informal on-street parking was gathered wherever possible.

We designed and carried out the survey in 20 PNR lots of SEQ. The PNR lot survey began a few minutes prior to the arrival of the first public transport service near the PNR lot and ended when either the lot was fully occupied or there were very infrequent arrivals. For each arriving car, its arrival time within a 5-min interval was recorded. Results suggest that most of the PNR lots are filled or reach a steady arrival pattern by 9: 30 am.
