With the rapid development of urban transportation, people urgently need high-precision and up-to-date road maps. At the same time, people themselves are an important source of road information for detailed map construction, as they can detect real-world road surfaces with GPS devices in the course of their everyday life. Big trace data makes it possible and provides a great opportunity to extr...

A major problem in road construction is the lack of timely and accurate information about the location and productivity of equipment. As a result, the productivity rate of certain types of construction equipment is low and equipment has to be hired in from third parties. Lack of co-ordination between the equipment department and the site manager is the major cause of these problems. In this pap...

Good quality base and sub-base material for road pavement construction is becoming increasingly scarce. Dolerite is one of the more abundant natural road building materials in South Africa. Yet, it seems that the road design and construction fraternity shy away from using it in favour of more expensive commercially produced crushed material – and so artificially increase the scarcity of natural...

traffic safety work is a goal common to all public authorities, police agencies and organizations in bavaria. reducing the number of traffic fatalities in a sustainable manner and continuing to lower the number of traffic accidents and road traffic injuries is a task for society as a whole. the various measures being implemented in bavaria during the road safety campaign “bayern mobil – sicher ...

Nowadays much emphasis is given to innovative procurement in the road construction sector. However, typical discussions about it do not focus on all the stakeholders involved in the process and all aspects. However, one cannot forget that procurement is a complex system, and everyone’s perspective is important for success. This paper looks at the worldviews of stakeholders in the road construct...

Forest roads are the base infrastructure foundation of forestry operations. These roads entail a complex engineering effort because they can cause substantial environmental damage to forests and include a high-cost construction. This study was carried out in four sample sites of Giresun, Trabzon(2) and Artvin Forest Directorate, which is in the Black Sea region of Turkey. The areas have both st...

In this article, the evaluation of Greenhouse gases in road construction projects is approached from a life cycle perspective. The elements which have a major contribution to emissions are identified in order to develop a strategy to control and reduce them. For this purpose, a management information system (CO2NSTRUCT) was developed, supported by a database obtained through specialized bibliog...
