This paper analyses the measures that improve the level of service (LOS) to on-road public transport (ORPT), high-occupancy vehicles (HOVs) and emergency vehicles (EVs). Buses, trams and EVs account for only a small percentage of the total travel demand in a city. The issue for these users is not on the level of demand, but rather on the measures required to maintain and improve their LOS because of the important roles they all play in a city. Advanced signal operations have been implemented to give priority to ORPT. HOV lanes can be an effective tool in increasingly person throughput in a corridor and their effectiveness is dependent on how successful carpools are formed to utilise such a facility. The difficulty of enforcing compliance in the use of HOV lanes is well-known and it may be easier to detect, identify and enforce compliance based on vehicle types rather than vehicle occupancies. The technologies for EVs range from manually operated pre-emption of signal phases to GPS-based systems. Future research areas for the improvement of the LOS for these different road users are identified. (a) For the covering entry of this conference, please see ITRD abstract no. E217099.
