Demand and Supply of Transport Connections for Commuting in the Czech Republic - Geoinformatics for Intelligent Transportation - page 139

Fig. 2 Supply of public transport connections to analysed municipality in the Czech Republic
(2011)

The crucial aspect in this choice is existence of an alternative. If no public transport
connection exists the commuter must rely on individual transport. It is not an easy
task to evaluate the supply of public transport connection at the municipality level.
Commonly used indicator for such evaluating is the number of links servicing the
municipality. But this indicator suffers several problems, i.e. there can be only one
or a few frequent links connecting only several and still the same municipalities,
these links can arriving and departing at wrong time for commuting needs. We have
developed a new indicator for evaluating the supply of public transport connections
and defined it as the number of municipalities within 100 km from which analysed
municipality is accessible per number of municipalities within 100 km on 6, 7, 8, 14
or 22 o

clock in case of one-way travelling. The map (Fig. 2 ) shows spatial dis-
tribution of supply and on the

'

first look it is clear that the general distribution is
opposite to that in the previous map (Fig. 1 ). So the best accessibility by public
transport is in case of the biggest cities what is again con rmed by positive and

statistically signi cant (p = 0.01) correlation (R = 0.257). If only cities above

10,000 residents are analysed, the correlation is even 0.621.
Similarly also the spatial trend from west to east is evident and con rmed by

positive and statistically signi cant (p = 0.01) correlation (R = 0.277) which is even

bigger than in case of the population size. Also in this case correlation is higher
without municipalities below 10,000 residents but the increase is not as high as in
the previous case (R = 0.336).
