The turn-by-turn directions provided in existing navigation applications are exclusively derived from underlying road network topology information, i.e., the connectivity of edges to each other. Therefore, the turn-by-turn directions are simplified as metric translation of physical world (e.g. distance/time to turn) to spoken language. Such translation that ignores human cognition of the geogra...

Research in the field of evacuation management puts a strong focus on the development of optimal evacuation and control strategies. However, in operational evacuation management the means to monitor, manage, evaluate and control are limited. The authorities nevertheless have a strong need to understand the system, in order to properly guide evacuating traffic. This indicates the need for a simp...

Ubiquitous and mobile computing has become an important field in computer science. The provision, management and transmission of information within computer systems and for human-computer interaction is required for many applications and the individual needs of the mobile user are manifold. Due to information overflow it is difficult for the user to access specific pieces of information while k...

Differences in perceptual and cognitive abilities between the young and elderly have implications for in-car tasks. As a primary example, although in-car navigation systems enhance situational awareness, this comes at the cost of increasing visual distraction and cognitive load. To address these shortcomings, this paper explores the efficacy of multi-modal cues for providing route guidance info...

Safety concerns have prompted designers of in-vehicle route guidance and information systems (IVRGIS) to make more use of an 'audible interface' to convey guidance instructions. Previous research has shown that, contrary to expectations, detailed guidance instructions can have a detrimental effect upon wayfinding performance, particularly for elderly individuals. In response to these findings a...

Recent studies on empirical data demonstrated the existence of macroscopic fundamental diagram (MFD), which expresses an aggregated model of traffic dynamics linking accumulation and output flow of an urban region. Employing MFD in modeling of urban networks opens up possibilities to introduce a new generation of real-time traffic control structures and improve mobility. Although there are stud...

Building an intelligent route guidance system is increasing important to ease traffic congestion pressure in fast growing cities, as a result of the urbanization trend. In another aspect, the network infrastructures promoted by the ideology of digital city reinforce the Intelligent Transportation Systems (ITS), which provides innovative resolutions to the challenge. As traditional centralized d...

Travel time data becomes widely available with the deployments of location-based technologies including GPS-equipped vehicles and cell phones, Bluetooth readers, Dedicated Short Range Communication devices, etc. This change has made a shift on the existing distance or historical speed based route guidance to travel time-based route guidance. For example, commercial GP-based navigation system ut...
