The study developed a microsimulation traffic modelling (MSTM) study framework which included selection of the appropriate modelling technique for on-road public transport (ORPT) priority analysis and guidance on organisation of an MSTM study for ORPT, including the critical variables and data set associated with MSTM analysis for ORPT priority initiatives. This study also looked into four ORPT priority treatments including: no priority, full bus lane, set back bus lane (SBBL) and queue jump bus lane (QJBL). Microsimulation experiments were conducted using a hypothetical network to examine the performance of the selected ORPT treatments. The analysis was conducted at two levels. The first level of analysis was to characterise the impacts and trade-offs in bus and car travel time of the four selected bus priority treatments, to provide guidance on the applicability of the selected bus priority treatments. The second level of analysis looked into specific design issues of SBBL and QJBL, including the following: (i) utilisation of the kerbside lane of an SBBL scheme, (ii) utility of the departure-side merge lane in a QJBL scheme and (iii) application of traffic signal priority in conjunction with SBBL.
