Transport connectivity is an important determinant of agglomeration economies and urbanization. However, measuring its impacts is a complex task when causality is considered. An important empirical challenge comes from potential endogeneity of infrastructure placement. To deal with the endogeneity problem, first, the paper constructs detailed georeferenced connectivity measurements based on micro shipping data collected over 10 years. Then, the system generalized method of moments regression is applied. Using unique data from the Caucasus and Central Asian countries, the paper estimates the impact of transport connectivity on agglomeration economies. It finds that agglomeration economies are significant and persistent in the region. Thus, the existing firm clusters are likely to continue growing. However, a constraint is also found. Large cities exhibit congestion diseconomies. Finally, the paper shows that the improvement of transport connectivity, especially local market accessibility, has a significant effect on agglomeration. By contrast, no clear evidence to support the impact of improved regional connectivity on agglomeration is observed yet. To take full advantage of agglomeration economies at the regional level, further efforts may be needed, for instance, toward increasing efficiency in transportation and logistics, improving the freight load, and/or reducing the time and costs of border crossing, which add to overall transport costs and times.

This volume presents the latest research on Roman roads, not just in terms of their basic infrastructure but also exploring various aspects of life that were connected with it, from the Imperial period to that of decline, acculturation and integration of new identities, within the three Roman provinces of Pannonia, Moesia and Dalmatia.

"This book examines the paved road as a liminal space and legal frontier for enlivened, everyday struggles over property, power, and place/definition. Through pavement itself and the pavement-based practices of pavementalities and pavementeering, the road is legally framed as a place for movement. Paved terrain is a site of dynamism between law and place that engenders the road as legal metaphor by calling forth the kinetic notion of jurisprudence in which law can be understood through the fluidity of everyday life. In Western, and particularly American society, roads are a material locus of governance, in which rights of way are determined, communicated and enforced. However, roads also constitute a site of resistance or disruption, beyond regulation. Addressing phenomena such as travel, political protest, public memory, and community governance, this book explores paved medium of asphalt as a complex surface for legality that constitutively frames order against disorder involving jurisdiction tensions, property ownership, and cultural identities in vehicular environments. The target audience of this book are those students and scholars who consider how law works in society whether through frameworks of (auto)mobility and legal geography or through the interdisciplinary approaches of legal semiotics, legal culture, and/or new materialism"--

This work aims to gain an understanding of the interactions between tread compounds and surface texture on dry and wet road conditions. If, for example, a corundum surface, which is very well-established in the tire industry, is used on the tire test bench instead of a real track surface, for wet track conditions ranking inversions in the tested compounds occur.

World and Hour in Roman Minds: Exploratory Essays seeks to penetrate Romans' consciousness of space and time, aspects of antiquity currently attracting intense interest. Historian Richard Talbert presents here a cohesive selection of nineteen essays, published over the course of thirty years, all but one previously appearing in widely scattered publications. Now reinforced by an Introduction and textually and visually updated, these essays document the progress of pioneering efforts to glimpse the worldviews of Romans up and down the social scale--even Julius Caesar and Claudius--and to reassess the communicative role of Roman mapping along with its strengths and limitations.Talbert interprets the Antonine Itinerary and Artemidorus and Peutinger maps afresh, visualizing the latter with a wider perspective than in previous scholarship and probing the challenges of its design, production and copying. He also casts doubt, however, on the idea that Romans conceptualized their long-distance roads as an interconnected system, as did certain comparable premodern states across the Americas and Asia.The most recent essays share findings that emerge with a shift of focus from space to time, specifically Romans' daily timekeeping by hours--another neglected dimension of their social mentalité. Talbert suggests that Romans' tracking of time should be regarded as uncannily similar to that of the Japanese before Westernization. Throughout, the essays are unified by the methods applied. The value of broader, often comparative, approaches is demonstrated, as well as the creative potential of untapped testimony and digital technology--altogether an invaluable platform to stimulate further inquiry.

This volume investigates the Roman city of Singara and the fortifications and roads in the surrounding area. The Rome / Persia frontier has been little studied, in part because of the difficulty of access for scholars, but was of great importance because it separated the two major civilisations of the early first millennium CE.
