"The UK Quiet Lanes Initiative, promoted by the Department of Transport, Local Government and the Regions through the Countryside Agency, considers how the character of country lanes can be preserved and made more attractive for non-motorised users whilst maintaining vehicle access for local residents. Motorised traffic in the countryside is rising quickly in the UK (Macafee, 2000). British attitude studies found that 73% of respondents agreed that "the amount of traffic on the roads is one of the most serious problems for Britain" (Stratford and Christie, 2000; p183). Public consultation in the research area (The Surrey Hills AONB, approximately 35 kms south from London) supported this finding, with residents expressing concern about driving speeds and the volume of traffic. In an area of special character such as this, it is important that traffic calming measures should not only be effective but also be in keeping with the rural surroundings in which they are to be engineered. Often, traffic engineering solutions are implemented in the expectation and hope that they will work, without trial beyond safety audits. Therefore, it is desirable to test the effectiveness of innovative engineering measures of this type before implementation, investigating which would most affect driver behaviour (especially speed) and which might alter use of the road away from primarily motorised traffic. This paper reports on a research study undertaken in the Surrey Hills, SE England, to predict the effectiveness of potential engineering measures used for traffic calming."
