In recent years increasing interest has been shown in developing policy responsive transportation models focusing on the alleviation of traffic congestion through encouraging people to switch modes. Much of this research has focused on the interaction between car and public transport and has ignored 'slow modes' such as walk or cycle.
As walk, in particular, makes up a significant proportion of the transport market it appears clear that any approach to developing an integrated transport policy must take on board both its current and potential share of the market.
Indeed, policy makers are now coming under increasing pressure to develop policies which will increase the share of both cycle and walk through the introduction of new pelican and zebra crossings, the use of covered walkways, introduction of cycle lanes and dedicated pedestrian/cycle paths physically separated from roads.
This paper describes the development and calibration of a model developed to explicitly include 'slow modes' for Wycombe District and Bucks County Council. The model explicitly incorporates cycle and walk trips and is able to forecast the impact of the:
* improved pedestrian facilities;
* introduction of cycleways;
* enhancement of existing bus services; and
* changes of car in-vehicle times and parking charges.
For ease of computation the results reported relate only to the morning peak period (06:OO to 1O:OO) and to a subset of zones actually incorporated in the final models.
The use of such models may help lead to the development of a more balanced approach to infrastructure appraisal and may allow for the evaluation of enhancements to pedestrian and cycle routes within a similar framework to that used for mechanised modes.
