I. Introduction As urban populations continue to grow and the effects of climate change become increasingly apparent, there is an urgent need for sustainable transportation solutions. Traditional route planners often prioritize speed or convenience, neglecting the environmental impact of travel choices. This research addresses this critical gap by developing an eco-friendly route planner that balances efficiency with sustainability. The environmental impact of increased mobility demand, especially in urban environments, raises significant public concern and presents challenges that need to be addressed for long-term sustainability. The quality of life and economic prosperity in modern cities heavily depend on the efficiency and environmental friendliness of human and goods mobility. However, the opportunity to create new transport infrastructure is becoming increasingly limited, necessitating smarter use of existing resources. Our eco-friendly route planner aims to encourage the use of public transportation and other environmentally friendly modes of transport by providing users with comprehensive, easy-to-use tools that consider multiple criteria in route optimization. By doing so, we seek to make inherently ’green’ human transports more appealing and usable to urban residents and tourists alike. A. Background on logistics and environmental impact The logistics industry plays a crucial role in the global economy, facilitating the movement of goods and services across vast distances. However, this vital sector also contributes significantly to environmental degradation, primarily through greenhouse gas emissions. According to recent studies, transportation accounts for approximately 14% of global greenhouse gas emissions, with road freight responsible for a substantial portion of this figure [1]. As the demand for logistics services continues to grow, driven by ecommerce and globalization, the environmental impact of this sector is becoming an increasingly pressing concern. Traditional logistics operations have primarily focused on optimizing routes for speed and costefficiency. While these factors remain important, there is a growing recognition of the need to incorporate environmental considerations into route planning and overall logistics strategies. This shift is driven not only by increasing regulatory pressure but also by a growing awareness among consumers and businesses of the importance of sustainable practices [2]. B. Problem Statement: Need for eco-friendly routing in logistics Despite the increasing awareness of environmental issues, many logistics companies struggle to implement effective eco-friendly routing strategies. The challenge lies in balancing the often-competing demands of operational efficiency, cost-effectiveness, and environmental sustainability. Traditional routing algorithms and GPS systems typically optimize for the shortest distance or fastest travel time, without considering factors that significantly impact fuel consumption and emissions, such as: • Road gradients and topology • Traffic congestion patterns • Vehicle type and load Moreover, the complexity of incorporating these additional factors into routing decisions often exceeds the capabilities of conventional routing systems. This gap highlights the need for an intelligent, data-driven approach to eco- friendly route planning that can dynamically balance multiple objectives while providing practical, implementable solutions for logistics operations. C. Objectives of the research The primary goal of this research is to develop and evaluate an intelligent Eco-Friendly Route Planner that addresses the aforementioned challenges. Specifically, this study aims to: 1. Design and implement a machine learning-based route optimization system that considers both traditional logistics priorities (time, distance) and environmental factors (fuel efficiency, emissions). 2. Integrate real-world data sources, including road network information, historical traffic patterns, and vehicle efficiency data, to create a comprehensive model for eco-friendly routing. 3. Develop an adaptive algorithm that can optimize routes based on changing conditions and varying priorities (e.g., balancing delivery time constraints with emission reduction goals). 4. Evaluate the effectiveness of the proposed system in reducing fuel consumption and emissions compared to traditional routing methods. 5. Assess the scalability and practical applicability of the Eco-Friendly Route Planner in real-world logistics operations. II. Background and Related Work A. Existing Route Planning Algorithms Traditional route planning algorithms primarily focus on finding the shortest or fastest path between two points. Popular algorithms include: - Dijkstra’s Algorithm: A graph search algorithm that finds the shortest path between nodes in a graph. - A* Search: An extension of Dijkstra’s algorithm that uses heuristics to improve performance. - Contraction Hierarchies: A speed- up technique for shortest path computations in large graphs. B. Multimodal Route Planning Challenges Multimodal route planning presents unique challenges compared to single-mode planning: - Integration of diverse transportation networks (e.g., walking, cycling, public transit, driving) - Handling time-dependent aspects of public transportation schedules - Considering user preferences and constraints across different modes - Balancing multiple optimization criteria (time, cost, convenience, environmental impact) C. Eco-awareness in Transportation Systems Recent years have seen growing interest in incorporating environmental considerations into transportation systems: - Carbon footprint calculation for different transportation modes - Green vehicle routing problems in logistics - Eco driving assistance systems for individual vehicles However, comprehensive eco-aware multimodal route planning for individual travellers remains an under-explored area, which our research aims to address. III. Literature Review A. Theoretical Framework 1. Route optimization algorithms Route optimization has been a subject of extensive research in computer science and operations research. Traditional algorithms like Dijkstra’s algorithm and the A* search algorithm have formed the foundation for many routing systems [3]. However, these algorithms typically focus on finding the shortest or fastest path without considering environmental factors. More recent research has explored multi-objective optimization techniques that can balance multiple criteria. For instance, Demit et al. [4] proposed a biobjective approach that considers fuel consumption and travel time. These studies provide a theoretical basis for incorporating eco-friendly considerations into routing algorithms. 2. Machine learning in transportation The application of machine learning (ML) in transportation has grown significantly in recent years. Supervised learning techniques, particularly ensemble methods like Random Forests and Gradient Boosting, have shown promise in predicting traffic patterns and travel times [5]. Deep learning approaches, including Recurrent Neural Networks (RNNs) and Long ShortTerm Memory (LSTM) networks, have been applied to capture the temporal dynamics of traffic flow [6]. These ML techniques offer the potential to predict fuel consumption and emissions based on various factors, providing a data-driven approach to ecofriendly routing. 3. Environmental impact assessment in logistics Several models have been developed to assess the environmental impact of transportation. The CMEM (Comprehensive Modal Emissions Model) and MOVES (Motor Vehicle Emission Simulator) are examples of sophisticated tools used to estimate vehicle emissions based on various parameters [7]. These models provide a foundation for quantifying the environmental impact of different routing decisions. B. Related Studies C. Research Gap While existing research has made significant strides in both route optimization and environmental impact assessment, there remains a gap in integrating these approaches into a comprehensive, real-time ecofriendly routing system for logistics operations. This study aims to address this gap by combining advanced ML techniques with multi-objective optimization, implemented in a scalable cloud-based system. IV. Methodology A. Data Pre-processing To prepare our data for machine learning models, we employ several pre-processing techniques: 1. Label Encoding We use Label Encoder to convert categorical variables such as weather descriptions, states, and countries into numerical format. This allows our models to work with these categorical features effectively. 2. Feature Scaling We apply StandardScaler to normalize continuous features including latitude, longitude, elevation, and temperature. This ensures that all features contribute equally to the model and improves convergence speed during training. B. Machine Learning Models 1. Gradient Boosting Machine (GBM) We employ GradientBoostingRegressor as our primary model for predicting route costs. GBM is chosen for its ability to handle complex, non-linear relationships and its robustness to outliers. The model is trained on historical route data, considering factors such as distance, time of day, weather conditions, and transportation mode. 2. Optional Models - K-Means Clustering: We explore the use of k- Means to group similar routes, potentially improving prediction accuracy for less common route types. - Principal Component Analysis (PCA): PCA is considered for feature reduction, potentially improving model efficiency without significant loss of information. C. Optimization Algorithms 1. Dijkstra’s Algorithm We implement Dijkstra’s algorithm (specifically, networkx.dijkstra path) to find the shortest path in our transportation graph based on the predicted routecosts from our GBM model. 2. Graph-based Algorithms We use Network library for graph construction and manipulation: • networkx.Graph (): Constructs the graph with nodes representing locations and edges representing possible routes. • nx.draw (): Visualizes the graph for debugging and presentation purposes. • Nx.draw network edges (): Highlights the optimal path on the graph. D. Eco-Awareness Integration A key innovation of our system is the integration of Eco awareness into the route planning process: 1. CO2 Emission Calculations We implement a comprehensive CO2 emission model that considers: - Road characteristics (e.g., type, gradient) Travel speed - Distance travelled - Mode of transportation (e.g., walking, cycling, public transit, private vehicle) This model allows us to estimate the environmental impact of each potential route segment accurately. 2. Multi-criteria Optimization We incorporate eco-friendliness as a key optimization criterion alongside traditional factors like travel time and number of transfers. This allows users to choose routes that offer significant environmental benefits with minimal time trade-offs. E. Research Design This study employs a mixed-methods approach, combining quantitative analysis of routing efficiency and emissions with qualitative assessment of system usability and integration potential. This comprehensive research design allows us to not only evaluate the technical performance of our eco- friendly route planner but also to understand its practical implications and user acceptance.

The model is trained on historical data to predict fuel consumption and emissions for road segments under various conditions. 3.

Distribution of Route Costs Figure 4 presents the distribution of route costs in our dataset. The histogram reveals several interesting characteristicsof our route data: • A multimodal distribution, suggesting different categories of routes (e.g., short, medium, and longdistance) • The majority of routes fall within the 50-75 cost range • There are smaller peaks around 125 and 150, possibly representing longer or more complex routes This distribution informs our understanding of typical route costs and helps in identifying potential outliers or special cases that our model should address. Figure 4: Distribution of route cost E. Implications of Results The strong performance metrics and visualizations demonstrate the effectiveness of our eco-friendly route planner in accurately predicting and optimizing route costs. The high accuracy in both regression and classification tasks suggests that our system can reliably identify and recommend eco-friendly routes while maintaining efficiency. The close alignment between actual and predicted costs, as well as the model’s ability to capture the nuanced distribution of route costs, indicates that it can handle a wide range of routing scenarios. This versatility is crucial for real-world applications where routes can vary significantly in length, complexity, and environmentalimpact. F. System Performance Evaluation 1.
