The deployment of
decision support systems multi-modal or otherwise is currently frequently
limited by many factors. The following
are examples that have been encountered:
|
|
Limitations in
data provided by one or more modes of transportation – typically arterial
data is a limiting factor but lack of full integration of field element
systems also contributes to the problems, as does partial data for transit
systems
|
|
Communications
network limitations i.e. interfaces are lacking between mode specific systems
|
|
Lack of
standardization of data flows- implementation of standards such as TMDD and
others support the way forward but have yet to be fully deployed
|
|
Shortages in
properly-trained personnel
|
|
Data gaps caused
by underfunded system maintenance
|
|
Reluctance of
certain modal operators to trust the control results of DSS and inability to
fine tune to suit their preferences and experience
|
|
Inherent
limitations of certain transportation modes, e.g. city TMC’s not monitored on
a continuous basis, legacy signal systems which cannot be monitored or
manipulated automatically, rail and transit information not fully and
accurately available in real-time, public safety systems using different
protocols.
|
|
Lack of
stakeholder organization and awareness – the Integrated Corridor Management
Pilot programs expose the need and extent of cooperation needed
