9.5.1 Bicycle compatibility index (BCI)AdvantagesThe BCI measure is flexible and simpleto use and can be used to distinguishbetween conditions on roads duringdifferent periods.As Table 9.2 (see opposite)demonstrates, a minimum of data isrequired to determine a BCI/LOS resultfor an entire route. The data is readilysourced in most instances.DisadvantagesBCI does not account for:• low traffic volume environmentswhere cyclists readily integrate withother traffic• significant intersections• strategic considerations such as routedirectness, coherence and purpose• paths. A similar US-developed processis available for paths, but it is not knownwhether the two methods may not becompatible for comparing path androad options.RecommendationsThe BCI method is most usefulwhen comparing mid-block routeoptions at an early stage, andwhen a quick and simple methodis desirable.9.5.2 Cycle review LOSAdvantagesThis is more comprehensive than the BCImethod. Among other factors, it givesbasic consideration to intersections androute directness, and includes paths.DisadvantagesA significant volume of data is required.It can be time consuming to compareseveral quite different route options.RecommendationsThis comprehensive method (IHT et al, 1998) can be used to examine existing infrastructureand to compare different route options provided concept proposals for routes arereasonably well defined.It should be used at a level appropriate for each route.Straightforward situations with obvious choices will not gain much benefit from the fulldepth of the process, but will nevertheless benefit from analysis based on its concepts.It can be used to assign an overall LOS score for a route proposal.9.5.3 Florida bicycle LOSThis method is the most widely used approach in the USA. It assesses bicycle LOS onlinks and straight through intersections as part of a multi-modal assessment of LOS.It is based on the research by Landis. The method includes a computer program tosimplify the calculations. Refer to Florida DOT (2002).9.6 Which method?Further researchFurther investigation into theappropriateness of the above methodsfor application in New Zealand isrequired and will be undertaken.Local authorities are invited to contactthe LTSA with a view to participatingand/or leading trial projects.Practitioners are encouraged to assessother methods where appropriateand available.RecommendationsUse a mix of the methods outlined above.A needs assessment is always important. In general, many of the issues associated withdeveloping a cycle route are qualitative, and only this type of assessment will considerall the overarching issues.For a quantitative assessment, the cycle review LOS method appears to be themost useful.Individual RCAs are encouraged to consider implementing a cycle audit and cyclereview style of process, and to work with the LTSA to develop a New Zealandrecommended process.A review of crash records (see section 7.3.2) is also worthwhile when assessing existingconditions.Two aspects stand out as being important in any cycling assessment:• Does the facility meet the users’ needs?• ‘The choice of routes in urban areas is largely determined by the extent to whichjunction features can be resolved where the cycle route meets or crosses moreheavily trafficked roads’ (Ove Arup and Partners, 1997).62
