A Review of Trip Planning Systems.

This report reviews current information provision in all modes of transport and assesses the needs for and benefits of trip planning systems. The feasibility of trip planning systems is discussed given the current state of technology and information availability and supply. The review was stimulated by technological developments in telecommunications and information technology which are providing the possibility of a greatly enhanced quality of information to aid trip planning decisions. Amongst the conclusions reached were the following: Current information provision is considered deficient in many respects. Travellers are often unaware of alternative routes or services and many are unable to acquire adequate information from one source especially for multi-modal journeys. In addition, there is a lack of providing real time information where it is required (bus stops and train stations) and of effective interaction of static and real time information. Most of the projects, which integrate static and dynamic data, are single mode systems. Therefore there is a need for an integrated trip planning system which can inform and guide on all aspects of transport. Trip planning systems can provide assistance in trip planning (before and during the journey) using one or a number of modes of travel, taking into account travellers preferences and constraints, and effectively integrating static and dynamic data. Trip planning systems could adversely affect traffic demand as people who become aware of new opportunities might be encouraged to make more journeys. It could also affect travellers choice as a result of over-saturation of information, over-reaction to predictive information, and concentration on the same 'best' routes. However, it can be argued, based on existing evidence, that such a system can benefit travellers, and transport operators as well as the public sector responsible for executing transport policies. Travellers can benefit by obtaining adequate information to help them in making optimal decisions and reducing uncertainty and stress associated with travel. Public transport operators can benefit by making their services known to customers, leading to increased patronage. Public transport authorities can use the supply of information to execute their transport policies and exercise more control over traffic management

Spatial networks of electrotechnical wholesalers in the Netherlands: A GIS application

The electrotechnical wholesale businesses stimulate the flows of electrotechnical goods, such as materials for electric installation, cables, wire, switchcupboards, audio and video, lights etcetera, from the producers towards the final consumer. They have an intermediate position in the production column between the producers of electrotechnical goods and, among others, the retailers, electricians, building industry. To give this abstract concept of the 'production column' a concrete and spatial interpretation, we set out an inquiry among approximately fifty electrotechnical wholesalers in the Netherlands. This inquiry gave us more insight in the way these wholesalers operate. An important part of the inquiry consisted of questions about the locations of the suppliers and buyers. With postal codes and the use of GIS we were able to show the spatial network of the forward and backward linkages of this particular group of wholesalers. Also other topics, such as the mean distances towards the buyers, have been calculated. In this way we turned the economic concept of the organisation of the production column into a spatial concept of location and spread of the different links in the production column. The paper will consist of two parts. Firstly, an outline will be given of the organisation of the electrotechnical wholesale business. Secondly, the paper will content the recent location pattern of this type of wholesale businesses and the spatial network of the production column of electrotechnical goods.
