Abstract

Sensor location problem on a traffic network infrastructure is of great interest to researchers. Many models have been proposed to locate sensor optimally for travel time estimation. However, none of the models have considered the probability of sensors failure. This paper proposes a model to locate sensors for estimating travel time in the network. The proposed model takes into account the probability of failure of the sensors. In addition, the model is able to consider different combinations of the failed sensors in the network. Numerous deployments can be defined for locations of the sensors in the network, therefore an optimization algorithm termed the Floating Search Method is used to find the optimal locations. The proposed algorithm is implemented on Sioux Falls Network and on a part of Tehran Network. The results showed that the model can locate the sensors in the network considering failures to estimate travel time with acceptable accuracy.
