| Summary: | Pedestrian walking misbehaviour represents a severe problem to road safety.
Therefore, pedestrian behaviour classification is a perfect solution in providing safety
for both pedestrians and vehicles by exchanging movement information among entities
via wireless communication. However, wireless communication has critical issues
with network failure, and these issues significantly affect the communication system.
Thus, the framework involved two modules for pedestrian walking behaviour
classification in a vehicle-to-pedestrian (V2P) context is proposed. In the
methodology, this study discloses five useful stages. Firstly, mobile phone users'
irregular walking behaviour is investigated using a questionnaire to determine their
options on mobile usage in the street. Secondly, four different testing scenarios are
chosen to acquire pedestrian walking data using the gyroscope sensor, where the
essential features were extracted and selected. Thirdly, the pedestrian's behaviour is
recognized using grid optimizer in machine learning. Fourthly, four standard vectors
for pedestrian walking behaviour are developed. Fifthly, the performance of the
proposed classification methods is validated and evaluated against multiple scenarios
and features. Two sets of real-time data are presented in this work. The first one is
related to the questionnaire data, consisting of 262 respondent samples, while the
second set has 263 samples of pedestrian walking signals. The results indicate the
following: (1) From 262 samples, 66.80% and 48.10% of respondents use mobile
phones for calling and chatting, respectively. (2) 263 samples of participants are
obtained and analysed, and 90 features are extracted from each sample. (3) 100%
classification accuracy are obtained for each class (normal walking, calling, chatting,
and running) using the grid optimiser method in machine learning. (4) The precision
of classification using Euclidean algorithm for normal walking and calling is 70%. In
contrast, for chatting and running behaviour, the accuracy is 100% and 80%,
respectively. This study's implication serves the safety system in the V2P context by
programming the proposed framework as an application in smartphones for
exchanging pedestrian information to the vehicles for avoiding accidents. |
