Parallel traffic

As a parallel transport is known in the public transport the simultaneous offer of a connection among several modes of transport, transport companies or lines.

causes

The individual lines / transports are operated / managed by different transport companies or authorities, who each want to gain advantages from their own transports. In numerous cases, there is even a successful traffic that is diluted by additional parallel journeys by other companies, which may have apparently small advantages to offer the customer or are even cheaper to carry out. In most cases, the "worthwhile" journeys ( rush hour , weekend excursion traffic , school transport etc.) are also served, which reduces the utilization of the actual line / traffic at these statistically and economically important periods.

The parallel traffic results from operational reasons such as entry / exit journeys from and to the depot ( tram / bus ). In these cases, the branch (s) around the depot will be used more and more on certain sections of the route. These short trips confuse some passengers and usually take place before and after rush hour.

A line / route network has sections that have to be traveled by several lines / trains (so-called "bottlenecks"), e.g. B. in inner cities / station streets or in the vicinity of important train stations.

Several lines / routes that connect outside areas (outlying city districts, villages, etc.) run due to operational (previously no turning options available or to be (time-) consuming to practice there) or strategic (avoided changing through direct connections, political support of certain goals) needs to the city center or to an important crossing point / terminus.

consequences

Such traffic reduces the utilization of the individual lines or traffic. This results in an economic loss, which can lead to a relocation or cancellation of certain journeys and in some cases even to the complete suspension / cancellation of a line or route.
