These findings offer insights into user/stakeholder perceptions of current artificial intelligence applications in highway transport and their potential benefits. The thesis also evaluates limitations to artificial intelligence implementation in highway transport, providing valuable perspectives for policymakers, industry stakeholders, and researchers.

Keywords: Artificial Intelligence; highway transport; positive impacts; autonomous vehicles; sustainability; congestion; mobility; stakeholders.

1. INTRODUCTION[edit | edit source]

Transportation is an essential aspect of human life, enabling the movement of people and goods from one place to another. Transport is one of the main pillars of our society. The ubiquitous availability of transport opportunities and the possibility to reach almost any place in the world in a limited amount of time has fuelled and sustained globalization and the unprecedented economic growth of the last century [3]. The challenges that transportation specialists confront includes poor safety record, CO2 emissions, wasted energy, capacity problems and unreliability. The interest of transportation researchers and practitioners in applying artificial intelligence models to address some of the aforementioned difficulties has grown in recent years to improve the safety, efficiency, and environmental compatibility of transportation systems [1,2,4]. Highway transportation is the backbone of the global transportation system, accounting for more than 90% of total transportation worldwide. However, the highway transport system is facing numerous challenges, including traffic congestion, air pollution, accidents, and deteriorating infrastructure. 

European Commission (2019f) describes Artificial Intelligence as systems that display intelligent behaviour by analysing their environment and taking actions – with some degree of autonomy – to achieve specific goals [5]. One of the prime areas where artificial intelligence will make its most paradigm-shifting impact is transport [6]. Promising artificial intelligence applications in mobility and logistics are, for example, self-driving vehicles (cars, trucks, trains, barges), smart electric charging, predictive maintenance, self-learning energy and emission management, cooperative mobility, sharing economy and self-organising logistics [5]. This new breed of artificial intelligence -based mobility, despite its machine-orientation, has to be a user-centred technology that “understands” and “satisfies” the human user, the markets and the society as a whole [6]. 

Some of the current state-of-the-art artificial intelligence applications in highway transport that will be discussed in the research paper are as follows; Traffic Control/Management and Smart Traffic Lights, Autonomous Vehicles, Predictive Maintenance in Asset Management

The market for artificial intelligence technologies for traffic management is confidently leading in the field of hardware sales. This market segment is becoming a key aspect of traffic management. The data captured by the hardware is the backbone of the intelligent traffic system functions. The hardware includes sensors, outdoor cameras, automatic identifiers and vehicle locators using GPS (Global Positioning System) [7].

Autonomous Driving is arguably the next disruptive innovation [8]. Predictive maintenance is the continuous monitoring of an asset's or system's condition throughout its life cycle in order to forecast when maintenance is required [9,10]. Predictive maintenance and asset management are critical components of highway transport, which can be significantly improved with the application of Artificial Intelligence.

2. METHODOLOGY[edit | edit source]

2.1 Survey Design and Questionnaire Structure

The survey questionnaire was meticulously designed to encompass diverse aspects of artificial intelligence applications in highway transport. It consisted of a total of 20 questions, divided into four sections:

Section 1: Demographic Information (3 questions)

This section will collect information about the participants, such as their age, gender, and occupation.

Section 2: Current State-of-the-Art Artificial Intelligence Applications (5 questions)

This section will gather information on the current state-of-the-art artificial intelligence applications in highway transport and their effectiveness in improving safety, reducing congestion, and enhancing the overall efficiency of transportation systems.

Section 3: Benefits of Artificial Intelligence in Highway Transport (7 questions)

This section will examine the potential benefits of using artificial intelligence in highway transport, such as improving safety, reducing congestion, and enhancing the overall efficiency of transportation systems.

Section 4: Challenges and Limitations (5 questions)

This section will investigate the challenges and limitations of implementing artificial intelligence in highway transport, such as technical limitations, regulatory barriers, and ethical considerations.

The survey questions will be designed to ensure that the responses provide the necessary information to address the research questions and achieve the research objectives.

2.2 Survey Distribution

Utilizing digital platforms like Jot form, the survey was disseminated across various online channels, including social media, transportation forums, academic networks, and industry-specific groups. The survey was accessible for a predetermined period to obtain a broad and representative sample.

2.3 Data Analysis

The data collected through surveys, will be analysed using descriptive statistics and Microsoft Excel as the tool for analysis. Descriptive statistics will be used to summarize and present the survey results.

2.4 Mathematical Model

This model is for further research. To represent my thesis results in the multiple regression model, numerical values can be assigned to each category and create a model based on the reported percentages [11]. Let's assume the positive impact of artificial intelligence in highway (Y) is influenced by the percentage of respondents mentioning each artificial intelligence application.

The model would look like this:

Y = b0 + b1X1 + b2X2 + b3X3 + b4X4 + ε

Where:

Y is the positive impact on the highway.

b0 is the y-intercept, representing the baseline positive impact when all variables are zero.

b1 represents the impact of autonomous vehicles on Y.

b2 represents the impact of intelligent traffic management systems on Y.

b3 represents the impact of predictive maintenance systems on Y.

b4 represents the impact of smart traffic lights on Y.

X1, X2, X3, X4 are the percentages of respondents mentioning each artificial intelligence application, respectively

ε is the error term.

Now, interpret the coefficients b1, b2, b3, b4 to understand the relative impact of each artificial intelligence application on the positive impact of artificial intelligence in highway transport. This model allows you to quantify and analyse the contributions of different artificial intelligence applications, providing valuable insights for highway engineering.

4. DISCUSSION AND CONCLUSION[edit | edit source]

With the primary aim of this research in mind which is to analyse and present the positive impact of artificial intelligence in highway transport from a stakeholder perspective, the summary of the results gotten from the analysis is discussed below.

The demographics results of this research survey shows that the participants were majorly from age groups 20-29 and 30-39 while a lower percentage was from ages 40-49 and 50 above. This shows that the perception of artificial intelligence's positive impact in highway transport stems from a more tech-oriented and adaptable age group. From the analysis, 71% out of the 100 participants in the survey makes up the male gender and this is because the target audience for this research survey was majorly highway transport professionals which is evident in the occupational distribution with 60% responses from engineers which we all know is a male-dominated the time of this publication. The mathematical model is for further research. It comes into play when you want to represent the thesis results gotten from the survey in a multiple regression model. This model allows you to quantify and analyse the contributions of different AI applications, providing valuable insights for highway engineering.

In this research we focused on improved safety, reduced congestion and overall efficiency as the main areas of artificial intelligence positive impact in highway transport [1,2,4]. From the results, the perception of respondents show that reducing the number of human errors (38 respondents) and providing real-time traffic updates (37 respondents) are the major ways artificial intelligence can improve safety in highway transport. Optimizing traffic flow and providing alternative routes to avoid congestion are the major ways respondents (44 & 39 respondents respectively) perceive artificial intelligence to reduce congestion in highway transport. The results show that majority of the responses (65 out of 100 respondents) perceive that optimizing public transportation routes and schedules will enhance the overall efficiency of highway transport. From these results, it shows major areas users/stakeholders perceive artificial intelligence can be beneficial and also traffic issues that needs to be addressed from a user focused perspective.
