Trip planning systems are defined and research undertaken for the Science and Engineering Research Council (SERC) in determining such systems is outlined. The authors describe market research that was undertaken to determine the role for trip planning systems. They also describe work in testing proposed systems, through the development of a telepho...
This paper reports on work that was initiated in February 1989 to develop a simple model that can accurately predict the usage of new stations in the Greater Manchester area. The starting point for this study was the work carried out by Moss in 1988 in which an attempt was made to develop a new station demand model based on patronage data for 9 of...

... Trip end and flow models require a station catchment to be defined, which serves as the unit of aggregation for relevant data such as population. Two methods are commonly used: a buffer around a station, such as the 0.8km and 2km radial catchments proposed by Preston & Aldridge (1991); or dividing the population into zones and allocating each zone to its nearest station, for example Blainey (2010) assigned census output areas based on road travel time. Both methods produce deterministic catchments, where a particular trip origin falls within the catchment of a single station, and stations are implicitly assumed to not compete with one another. ...
... The system must be capable of simultaneous data acquisition, processing and dissemination of the traffic/travel advice in real-time to a full spectrum of end users. Preston et al. (1993) proposed the use of invehicle telephones to communicate with a remote computer. The increasing use of mobile phones by the general public takes their suggestion one step further, opening access to the decision support system to many more users. ...
