The ability to perform vehicle tracking is very useful in daily life — today, such as security on personal vehicles, public transportation systems, fleet management and other mass transit. In this study, we designed an application of Geographic Information Systems (GIS) that will be applied to public transport services. This system provides real-time position tracking of each vehicle (taxi) and capable...
The Delay Tolerant Networks (DTN) approach is considered the best strategy to address the specific issues of the VANETs, namely high mobility, variable node density or frequent radio obstacles. Several protocols have been proposed for DTNs, being the epidemic routing (and variations of it) the most representative protocol. Nevertheless, the availability of navigation systems, thanks to which each...
In order to construct the highway networks, the road tunnels become an inevitable deign to accommodate physical environment elements (e.g., mountains and rivers) in the world. For the recent constructed tunnels, the communication system within the tunnel is planed and designed ahead of time. However, the cost to build and maintain a complete communication system for existing tunnels may not be a cost...
VANET (Vehicular Ad-hoc Network) that is used for vehicular-to-vehicular and vehicular-to-roadside communication is well known as one of the representative application of ad hoc networks. One of the representative mechanisms is Epidemic Routing that adopts the concept of Store-Carry-Forward. However, in Store-Carry-Forward mechanism, each node stores data packets in the buffer, and whenever the node...
The vehicle routing problem is an important problem in logistics. And it has taken as the NP hard problem. Most of the researchers want to get the best resources by many kinds of ways. But the real-world problem is much more difficult than the VRP. In order to make the model and get the solving strategy for the real-world VRP, the paper analysis the customers' demands and divides the problem into...
Recent years, spatial data and distributed sensing data, such as digital road map, traffic route, vehicle speed, event recording and others, are integrated and stored into the spatial temporal database systems. In this paper, we focus on GIS-based scheduling applications using GPS tracking devices and spatial database for the actual vehicle routing problems. Vehicle Routing Problem (VRP) is the one...
The paper describes a practical model for routing and tracking with mobile vehicle in a large area outdoor environment based on the Global Positioning System (GPS) and Global System for Mobile Communication (GSM). The supporting devices, GPS module-eMD3620 of AT&S company and GSM modem-GM862 of Telit company, are controlled by a 32bits microcontroller LM3S2965 implemented a new version ARM Cortex...
