Developments in many different areas over the past 20 years serve to ameliorate many of these concerns and make PRT an option worth exploring further. This computational power allows for better simulation modelling ability and network design capability. Control theories for automated systems have matured due to the considerable investment made during the 1970's. Combined with the computational power available today, these theories can be simulated and compared using a hypothetical network. Advancements in LIM technology have reached a highly developed stage.
Powerful microprocessors are available that are both abundant and inexpensive.
These components serve to increase the on-board capabilities of the vehicles and improve the system performance, reliability, and safety. Automated fare collection technologies have been developed and proven in current public transit applications. Use of these technologies would serve to simplify fare collection and reduce labor cost. These observations, combined with the growing need to improve the level of service that public transit provides, suggest that PRT be seriously studied as a realistic new mode of transportation.
