Traffic intersections are incredibly dangerous for drivers and pedestrians. Statistics from both Canada and the U.S. show a high number of fatalities and serious injuries related to crashes at intersections. In Canada, during 2019, the National Collision database shows that 28% of traffic fatalities and 42% of serious injuries occurred at intersections. Likewise, the U.S. National highway Traffic Administration (NhTSA) found that about 40% of the estimated 5,811,000 accidents in the U.S. during the year studied were intersection-related crashes. In fact, a major survey by the car insurance industry found that nearly 85% of drivers could not identify the correct action to take when approaching a yellow traffic light at an intersection. One major reason for these accidents is the “yellow light dilemma,” the ambiguous situation where a driver should stop or proceed forward when unexpectedly faced with a yellow light. This situation is even further exacerbated by the tendency of aggressive drivers to inappropriately speed up on the yellow just to get through the traffic light. A survey of Canadian drivers conducted by the Traffic Injury Research Foundation found that 9% of drivers admitted to speeding up to get through a traffic light. Another reason for these accidents is the increased danger of making a left-hand turn on yellow. According to the National highway Traffic Safety Association (NhTSA), left turns occur in approximately 22.2% of collisions—as opposed to just 1.2% for right turns. Moreover, a study by CNN found left turns are three times as likely to kill pedestrians than right turns. The reason left turns are so much more likely to cause an accident is because they take a driver against traffic and in the path of oncoming cars. Additionally, most of these left turns occur at the driver’s discretion—as opposed to the distressingly brief left-hand arrow at busy intersections. drive Safe Now proposes a workable solution for reducing the number of accidents occ

Location prediction in social media， a growing research field， employs machine learning to identify users’ locations from their online activities. This technology， useful in targeted advertising and urban planning， relies on natural language processing to analyze social media content and understand the temporal dynamics and structures of social networks. A key application is predicting a Twitter user’s location from their tweets， which can be challenging due to the short and unstructured nature of tweet text. To address this challenge， the research introduces a novel machine learning model called the location-aware attention LSTM (LAA-LSTM). This hybrid model combines a Long Short-Term Memory (LSTM) network with an attention mechanism. The LSTM is trained on a dataset of tweets， and the attention network focuses on extracting features related to latitude and longitude， which are crucial for pinpointing the location of a user’s tweet. The result analysis shows approx. 10% improvement in accuracy over other existing machine learning approaches.

The mobility and connective capabilities of unmanned aerial vehicles (UAVs) are becoming more and more important in defense, commercial, and research domains. however, their open communication makes UAVs sus***,theinefficiencyoftraditional cryptography-based techniques has led to the addition of Physical Layer Security (PLS). This study focuses on the advanced PLS method for passive eavesdropping in UAV-aided vehicular environments, proposing a solution to complement the conventional cryptography approach. Initially, we present a performance analysis of first-order secrecy metrics in 6G-enabled UAV systems, namely hybrid outage probability (hOP) and secrecy outage probability (SOP) over 2 × 2 Nakagami-m channels. Later, we propose a novel technique for mitigating passive eavesdropping, which considers first-order secrecy metrics as an optimization problem and determines their lower and upper bounds. Finally, we conduct an analysis of bounded hOP and SOP using the interactive Nakagami-m channel, considering the multiple-input-multiple-output configuration of the UAV system. The findingsindicatethat2×2Nakagami-misasuitablefadingmodelunderconstantvelocityfortrustworthyreceivers and eavesdroppers. The results indicate that UAV mobility has some influence on an eavesdropper’s intrusion during line-of-sight-enabled communication and can play an important role in improving security against passive eavesdroppers.
