This book deals with the estimation of travel time in a very comprehensive and exhaustive way. Travel time information is and will continue to be one key indicator of the quality of service of a road network and a highly valued knowledge for drivers. Moreover, travel times are key inputs for comprehensive traffic management systems. All the above-mentioned aspects are covered in this book. The first chapters expound on the different types of travel time information that traffic management centers work with, their estimation, their utility and their dissemination. They also remark those aspects in which this information should be improved, especially considering future cooperative driving environments.Next, the book introduces and validates two new methodologies designed to improve current travel time information systems, which additionally have a high degree of applicability: since they use data from widely disseminated sources, they could be immediately implemented by many administrations without the need for large investments. Finally, travel times are addressed in the context of dynamic traffic management systems. The evolution of these systems in parallel with technological and communication advancements is thoroughly discussed. Special attention is paid to data analytics and models, including data-driven approaches, aimed at understanding and predicting travel patterns in urban scenarios. Additionally, the role of dynamic origin-to-destination matrices in these schemes is analyzed in detail.

La investigacion da la oportunidad de conocer al nino, lo cual brinda la expectativa de tener una vision retrospectiva de nuestro propio desarrollo, dirigido tanto a padres como a profesionales interesados en el estudio del nino. La teoria de Wallon, por medio del materialismo dialectico, enmarca al individuo en interaccion con su medio y aborda la identidad del hombre en diferentes aspectos, entre los que considera lo biologico y lo social como complementarios en el proceso de su formacion y desarrollo para conformar su vida psiquica bajo un modelo de relaciones reciprocas y reafirmando el papel del otro, en su desarrollo individual y dinamico. Al describir como se relaciona el nino con los demas, identificando sus lazos de afecto en ninos y ninas con un rango entre ocho y once anos de edad, su mundo se amplia por el contexto escolar, lo que propicia en el nino caracteristicas especiales determinadas por la preponderancia de actividades intelectuales sobre las conductas afectivas, para la superacion de su sincretismo."
