In that context, the French Transport Regulatory Authority (Autorité de régulation des transports, ART) has identified some new challenges posed to regulators:
First, increased competition between transport modes due to digitalisation questions the definition of relevant markets and, in turn, the definition of dominant positions. Some of the underlying questions include: should regulators (transport regulatory bodies as well as competition authorities) maintain a modal approach or define relevant markets as multimodal? How and to what extent should regulators take into account the risks associated with transport operators’ diversification (leverage effect)?
In addition, increased competition between transport modes also inevitably questions the scope of intervention of transport regulators and their capacities to analyse and take into account intermodal competition (e.g. between trains and coaches or between air-planes and high-speed trains) to efficiently regulate. Some of the underlying questions include: Is it relevant to maintain “mono-modal” regulators? Shouldn’t transport regulators be multimodal transport regulators?
Finally, with digitalisation, the control of intangible assets like data by transport operators may increase the risks of exclusionary conducts. As observed when the airline transport market was liberalised, the control over computerised reservation systems by incumbent transport companies may be used to foreclose competitors on the downstream markets. Similarly, the control over information/data on traffic, timetables, customer bases, etc. may provide a non-replicable advantage causing the exclusion of competitors on the transport market. Some of the underlying questions include: To what extent should transport regulators (and more generally sectoral regulators) be in charge of guaranteeing fair, transparent and non-discriminatory access to intangible assets/facilities that affects the intensity of competition on the transport service market?
