      <title>Technical Solutions for Improving the Lateral Protection of N1 Category Vehicles</title>
      <link>https://trid.trb.org/View/2579336</link>
      <description><![CDATA[This paper focuses on the development and implementation of innovative technical solutions for improving the side protection of light commercial vehicles (category N1) in the context of road traffic. Commercial vans are taller and heavier than passenger cars. Also, they usually have the stiff structure at a higher height. Typically, vans have fewer occupants but carry a larger load. In the event of a crash, the geometric misalignment, rigid structure, and greater mass will affect the occupants of the smaller vehicle, resulting in a greater likelihood of serious injury or death to the occupants of the car. The safety of light commercial vehicle occupants has only partially benefited from the advances in vehicle safety over the past decade. Because of differences in mass, side collisions involving light commercial vehicles tend to have more severe implications for opponent vehicles. The results obtained will increase the safety of N1 vehicles in case of collisions involving occupants in real road traffic conditions.]]></description>

      <title>The Automobile, from a Glorious Past to an Uncertain Future</title>
      <link>https://trid.trb.org/View/2579326</link>
      <description><![CDATA[The work aims to present the main historical stages that marked the evolution of the automobile from a technical curiosity to an indispensable means of transport, intimately linked to the everyday life of mankind. It all started from the sketches of Leonardo da Vinci (how could it be otherwise?) who designed a self-propelled vehicle that he did not physically realize. More than 300 years later, the courage of a lady, Bertha Benz, who in 1888 undertook the first significant journey in an automobile powered by an internal combustion engine made by her husband, Karl Benz, introduced the automobile into the world of mankind. Since then, the car has seen a rapid evolution, being adopted with enthusiasm despite the numerous criticisms that have been addressed to it over time. Nowadays, the problems related to its impact on the environment and the prospect of exhausting the Earth’s resources has led to the investigation of alternative propulsion systems and even to the change of the paradigm under which the automobile will be perceived in the future. The global impact (social, economic, infrastructural and even political) that this new approach will impose has not yet been precisely assessed, which makes uncertain the future of this beloved means of transport.]]></description>

      <title>Evaluation and Analysis of Public Transport Services for County Seat Municipalities in Romania</title>
      <link>https://trid.trb.org/View/2581417</link>
      <description><![CDATA[The paper presents an analysis of municipal public transport services for Romania. The services operated in all County Residence Municipalities of the country were analyzed. The quality of public transport services depends largely on strategic, tactical and operational decisions applied in the public transport system, depending on budget limits. These decisions concern in particular the determination of public transport routes, the frequency of the transport service, the type of services offered, waiting times and transit times. Quality of service is an indicator of the success of a public transport operator, which has direct implications for passengers. Following the centralization of data on these parameters, provided by the 41 City Halls of County Residence Municipalities in Romania and those collected on site and from open sources - sites (transport operators, city halls, county councils), resulted the worksheets necessary for comparative analysis. A methodology for scoring the 8 indicators was proposed, in order to result in a cumulative score representing the level of quality of the public transport service in each analyzed municipality. A hierarchy of the 41 analyzed municipalities was made and recommendations were made in order to increase the quality of services in the future. The paper presents the results of the material produced with the financial support of Active Citizens Fund Romania, a program funded by Iceland, Liechtenstein and Norway through the EEA Grants 2014–2021.]]></description>
