This research aims to assess the impact of using texting, web surfing and navigating applications on driving behavior road safety in urban environments. The study involved collecting data from 36 young adult drivers through a simulator experiment, supplemented by survey gather participant characteristics profiles. experiment included periods distraction-free intervals when used Facebook (scrolling feed), Google Maps (searching for specific locations), Messenger (texting). Data analysis...
The present study aims to investigate the benefits of eco-driving in urban areas and on highways through an experiment conducted a driving simulator. Within group 39 participants aged 18–30, multiple scenarios were conducted, both without with guides, assess impact behavior environmental sustainability safety outcomes. Data pollutant emissions, including carbon dioxide (CO2), monoxide (CO), nitrogen oxides (NOx), as well crash probability, collected during experiment. relationships between...
This study aims at evaluating the impacts of different operational speeds an autonomous shuttle bus service on road safety by increasing Connected and Automated Vehicles (CAVs) Market Penetration Rate (MPR) combining network characteristics. A microscopic simulation analysis was performed in order to quantify impact automated within traffic. In traffic Villaverde, Madrid, several scenarios were simulated using Aimsun software considering various CAV MPRs (0%–100%), service, namely 15, 30, 45...
In the era of automation, autonomous point - to shuttles are said be among first mobility on demand service that will emerge. But, what impacts such a in implementation area? The scope present paper is assess an shuttle bus traffic conditions, road safety and environment. For this purpose, route was designed operate part Athens network various scenarios have been developed including peak off hours, existence dedicated lane for bus, incident occurrence as well different penetration rates...
High-capacity Connected and Autonomous Vehicles (CAVs) are expected to be extensively utilized by on-demand services. This paper aims assess the impacts of large-scale autonomous mobility services on traffic, environment, road safety, under various service specifications using microsimulation. To that end, an urban shuttle was designed, optimized, based a variation Dial-a-Ride optimization problem (DARP), implemented in network city Athens serve different portions demand with capacity...
The paper proposes a general framework for the assessment of impacts introduction Connected and Automated Transport Systems (CATS) on traffic. main objective is to address question scalability transferability identified Autonomous Vehicles (AVs) in particular, focusing network performance urban areas. A combination microscopic macroscopic simulations as well statistical methods are applied. Microscopic simulation conducted measure changes capacities by utilizing concept Macroscopic...
The present study aims to investigate the impact of texting and web surfing on driving behavior safety young drivers rural roads. For this purpose, data were gathered through a simulator experiment with 37 drivers. Additionally, survey was conducted collect their demographic characteristics preferences. During experiment, distracted using contemporary smartphone internet applications i.e., Facebook Messenger, Google Maps. Regression analysis models developed in order identify effect...
Rapid technological advances leave limited margins for the preparation of cities to receive Connected, Cooperative and Automated Mobility (CCAM). The LEVITATE project endeavours develop an open access web-based Policy Support Tool (PST), that will provide decision makers at all levels with methodologies results. aim PST is consolidate outputs different methods into overall framework assessment impacts, benefits costs CCAM, automation penetration on time horizons. comprises two modules:...
Abstract The widespread adoption of Connected and Automated Vehicles (CAVs) is being propelled, not only in the realm private vehicles but also within transit systems. This development serves to enhance urban transport activities, rendering transportation more appealing passengers. present study aims identify examine safety effects testing different operational speed shuttle bus services various future mobility conditions. To investigate impacts autonomous further their speed, microscopic...
The increasing penetration of autonomous vehicles (AVs) presents new challenges and opportunities for road safety. This study aims to evaluate the impact AV rates on traffic safety through use microscopic simulation scenarios based Villaverde network in Madrid. Eleven were simulated with SAE Level 5 market (MPRs) ranging from 0% 100% 10% increments. Vehicle conflicts, defined as instances where time collision was less than 1.5 s, analyzed along composition roadway characteristics. Multiple...
Connected and automated transport systems are expected to be the first align with their large-scale business cases by enhancing urban transportation activities. The present study aims assess traffic environmental impacts of different operational speeds shuttle bus service through microscopic simulation. In this context, scenarios were formulated simulating Villaverde district in Madrid, Spain. analysis results provided multiple measurements quantifying services Market Penetration Rates...
This research aims to investigate the impact of smartphone texting and web surfing on driving behavior road safety when in an urban environment. For this purpose, data from 36 young drivers were collected a simulator experiment; addition, survey was conducted collect characteristics profiles participants. The experiment included with no distraction time intervals driver distracted by using Facebook, Google Maps Facebook Messenger. analysis, linear binary logistic mixed models developed...
The significant increase in freight transport during an after the COVID-19 era, is leading to a continuous number of trucks and their proportion traffic conditions. objective present study quantify impact on environmental conditions motorway. To achieve this objective, data from Nea Odos Motorway were used for period two months 2021. Within analysis framework, micro-simulation was order examine impacts mainly traffic, environment energy efficiency network level different penetration rate...
In the city of Athens, traffic delays and high travel times are noticed due to levels inner-city traffic. Consequently, sustainable mobility practices, such as enlarging sidewalks, parking management prioritizing pedestrians public transport imperatively required. Within framework new Sustainable Urban Mobility Plan a series novel arrangements were examined, promoting active modes. This paper aims assess impacts arrangements, examine interventions that upgrade space in Athens present an...
Automation in urban freight transport is an important milestone for city logistics, but it challenging due to the complex traffic situations. While parcel volume soaring popularity of e-commerce – and especially accelerated by COVID, cities are thinking about future delivery system. consolidation expected bring disruptive changes system we know today. The aim present paper provide insight impact assessment method used results related Vienna. By applying analytical methods, show which impacts...
