Challenges and opportunities of vehicle manufacturers in improving access to taxis
Ladies & gentlemen, good morning and thank you for allowing me the opportunity to share my view on the “Challenges and opportunities of Vehicle Manufacturers in Improving Access to Taxis”, the case of LTI
My name is Paul Woolley, I am the Technical Director for LTI Vehicles. I have been with LTI for six years after 20 years automotive experience with Rover Group and BMW. You are all well aware of the Iconic London Taxi and the fact that it is globally recognised as the worlds leading accessible Taxi.
You are also well aware of the numerous features we have designed into the cab over many years, all as a direct result of feedback from our customers and key stakeholders, especially the many associations representing those who are less able.
LTI has long been campaigning for appropriate regulation which will set the standard for accessibility across Europe. It is our common goal that taxis, as a part of an integrated transport system are made as accessible as possible. However, the pursuit of the perfect vehicle should not be at the expense of what is possible.
It is essential that the regulations when published will be unequivocal practical and realisable.
I would like to take a few minutes to expand upon these three key thoughts.
Firstly, Unequivocal Standards
Each and every attribute described in the regulation must be described in a manner where by there can be no debate over compliance or otherwise. The report to date identifies many essential attributes, much thought and debate has gone into the proposed dimensions for accessibility but there is still much more work required to ensure absolute definition of each dimension. Only when this work has been completed will vehicle manufacturers finally be able to fully understand the true implications of compliance. This process should be carried out with the manufacturers to ensure practical solutions are identified.
Any standards that have room for debate over compliance will guarantee debate. Debate and argument will add time and cost to the process of implementation with too much time spent in legal argument at each part of the implementation process. The consequences obviously being delay in the access to accessibility we all aspire to.
Secondly, Practical
When defining attributes we must always ensure that the raison d’etre of that attribute is to improve some element of accessibility. Establish clearly what makes that particular feature work, what is important about it? For example: Wheelchair Space could be described as requiring a 1200 mm x 700 mm flat floor this is not true, not necessary. Wheelchair space actually only requires an area free from obstruction to the easy manoeuvrability of the regulation wheelchair.
Thirdly, Realisable
Over many years now a very significant amount of research has been carried out to establish the ideal accessible taxi. An excellent understanding has been gained in what is important and what is less so let us all make sure that we regulate for that that is realisable let us not let the perfect get in the way of progress.
So I submit three key thoughts for implementation.
Unequivocal
Practical
Realisable.
If I may, I would now like to discuss the design recommendations captured in tables 6, 7 & 8 in more detail and being more specific to the implications to LTI vehicles.
1. Entry Into The Vehicle
You will see from the table that the TX4 already complies with all the minimum entry requirements. However, it does not currently comply with the proposed recommended door height and floor height dimensions. Given sufficient time the floor height challenge could be met with appropriate design changes. The door height challenge however would require major redesign and could not practically be incorporated into the current base London Taxi design.
2. Vehicle Interior
Again referring to the matrix you will see TX4 complies with the minimum requirements for Interior headroom and wheelchair space (width). The challenge for us is wheelchair space (length) where we currently just fail to meet by 25mm. The practical implications of this is that the large foot rests on the standard wheelchair can sometimes be obstructed when manoeuvring the chair. This practical problem needs to be addressed by LTI and we are already planning to incorporate modifications into our next facelift. This change will be challenging and costly but we recognise the practical requirement for change and hence it will be delivered. It is important to re-iterate however that the current dimensions are more than satisfactory to load and manoeuvre most wheelchairs.
3. Table 8, Type One and Two dimensions and other features offers some fundamental and inappropriate challenge to a Type One vehicle
In a valiant attempt to share Type Two attributes with the fully accessible Type One taxi some significant oversights have been recognised.
The Type One taxi will obviously fair well when looking at interior space, a pure function of having sufficient space for the wheelchair.
The fact that there is enough space for the wheelchair obviously means that exit radius and door closure reach are impossible to meet. I would suggest these requirements are also not beneficial in a Type One vehicle as the semi ambulant will, with the aid of grab handles be able to stand inside the cab and walk out, a fundamentally different situation to that of the saloon vehicle.
Door release effort is another area of potential concern it is important to understand precisely how this is to be defined. As it stands at the moment, most vehicles would not comply even with the maximum release loads. In many instances it is in direct opposition to the anti burst crash requirements required for ECWVTA.
Further engineering investigation is required to ascertain realist targets.
Finally, the levels of lighting described in the taxi may be described as too bright for many customers and hence must be carefully reconsidered.
So in summary:
The LTI TX4 will meet all of the specific Type One minimum requirements.
There should be no blurring of the edges when it comes to defining Type One and Type Two vehicles. Clear requirements should be defined for each and clear differential always maintained.
I strongly support the principles of the report; however, one critical area that has not been addressed is the totally inappropriate practice of rear loading of wheelchairs. If a growth in the number of accessible taxis leads to a growth in the number of vehicles in our cities that require wheelchairs to be loaded from the rear, the report will be promoting practices that are clearly dangerous in normal city environments. I strongly urge the commission to re look at this whole issue, if it is not then a very significant opportunity to improve safety will be missed.
In summary
LTI strongly support the implementation of appropriate regulation, and I stress regulation. Unfortunately, I fear without regulation many licensing authorities across Europe will take little or no notice of simple guidelines.
LTI currently produce the only purpose built accessibility recognised across the world as a global icon of safety, reliability and accessibility.
We at LTI recognise the need to make continual improvements to the TX4. Those changes have to be driven by customer demands and regulation. Regulation comes in many guises, covering everything from vehicle emission to vehicle safety. Product change costs are a major part of the LTI vehicle cost base and could become a burden LTI cannot cope with. It is therefore essential that regulation is unequivocal, practical and most of all realistic.
Please do not let idealism get in the way of progress. We all desire accessibility to be accessible to all.
I would like to thank you for the opportunity to address you today and to convey my congratulations to all involved in the report especially Philip Oxley for providing an excellent foundation on which we can build.
