Abstract
Intelligent Transportation System (ITS) is essential for effective identification
of vulnerable units in the transport network and its stable operation. Also, it is necessary
to establish an urban transport network vulnerability assessment model with solutions
based on Internet of Things (IoT). Previous research on vulnerability has no congestion
effect on the peak time of urban road network. The cascading failure of links or nodes is
presented by IoT monitoring system, which can collect data from a wireless sensor
network in the transport environment. The IoT monitoring system collects wireless data
via Vehicle-to-Infrastructure (V2I) channels to simulate key segments and their failure
probability. Finally, the topological structure vulnerability index and the traffic function
vulnerability index of road network are extracted from the vulnerability factors. The two
indices are standardized by calculating the relative change rate, and the comprehensive
index of the consequence after road network unit is in a failure state. Therefore, by
calculating the failure probability of road network unit and comprehensive index of road
network unit in failure state, the comprehensive vulnerability of road network can be
evaluated by a risk calculation formula. In short, the IoT-based solutions to the new
vulnerability assessment can help road network planning and traffic management
departments to achieve the ITS goals.
