Personal Mobility

In the UK, buses carry more passengers annually than any other public transport (PT) mode (5 billion compared to rail’s 2 billion27). And they share the road with a growing number (over 30M) of vehicles for private transport and freight. There are congestion problems in almost every major town and city and this impacts directly on the ability of bus operators to adhere to bus schedules which reduces the overall service levels for the passengers. Part of the solution to the problem of congestion is satellite tracking of the buses to provide Real-Time Information (RTI) to passengers thereby allowing them to make informed and intelligent decisions about their travel.

The main objective of this research was to investigate four types of RGI (Route
Guidance Information) systems and evaluate the suitability of the systems, which will
improve safety and mobility of foreign drivers who drive temporarily in Japan. Twelve
foreign drivers were asked to operate a driving simulator while using four types of route
guidance information developed by utilizing arrow-type and map-type information. Glance
behavior including fixation time, glance frequency, and mental workload were measured.
Results suggest that the most suitable navigation system for foreign drivers is to provide
selectable information by driver’s control, which is supported by more explicit and simple
information than that of a current navigation system.

In Taiwan, freeway traffic is often congested during peak hour or during seasonal holiday periods. For deploying Advance Traveler Information System, to predict the travel time is essential. There are many various methods had been created to predict the travel time in the past. However, most of them are too complex. In this paper, a model using the Grey forecasting theory is adopted in views to its few data needed for getting prediction result within short term. The predicted result is good, especially for the travel time changed in short term. Furthermore, the improvement for overcoming the shortcomings by using simple Grey model is also conducted to reduce travel time fluctuation impact and then to enhance the prediction accuracy. The results implicate that these methods can do help to improve the prediction accuracy. A revised method of Grey travel time prediction model is then developed.

After briefly stating the principle of GPS technology, the paper synthetically analyzes  the research  background of the surv-control and navigation of GPS vehicle management system. Also its latest research situation in China and abroad is introduced. The paper emphasizes the study on the unique surv-control and navigation of GPS vehicle management system which adapts to the China’s situation.  Then the system’s design procedures are expounded and the
software’s frame and function of every section are set up. The software tool—MapInfo which can combine map with  text information perfectly and its notable characteristics of the table GIS are detailedly introduced. In the end, prospect of GPS and GIS applications in the surv-control and navigation of vehicle is looked into future. Based on analyzing and comparing the characteristic of three system program development software, MapBasic, VB, VC++ and comprehensive consideration VC++ is selected as the system development software.
