My guest this week is someone whom many of you may have seen

 

Welcome to the podcast Lisa.

Lisa: Thank you. Thank you for inviting me.

Simon: So, Lisa, you’re an Associate Professor of Driving Behaviour and Director of the Driving Research Group at Cranfield University. You previously founded companies like DriverMetrics, you were co-founder of The Floow. But you’ve now founded a new company called PsyDrive – all of which were to, kind of, commercialise some of the valuable research that you’ve done and make those learnings available to fleet operators. So, perhaps you could start by telling us a little bit about what you’re working on at the moment.

Lisa: Sure. So, with Cranfield, some of the work I’m doing right now is looking at behavioural adaptation in response to autonomous vehicles. And so, we’re running a series of studies in the field, looking at how people change their behaviour in response to automated systems over time. A lot of people think that driverless vehicles are going to be safer, but I think there are some things that we really need to understand a bit more about first.

So that’s my work with Cranfield. And then, with PsyDrive I essentially developed an accredited CPD course on Human Factors in driving, which is available for fleet managers and anybody working in the fleet industry really, to help them understand a bit more about driver behaviour.

Simon: Excellent. Now, this episode of our podcast is part of a range of content we’ve created this quarter around the theme of fitness to drive – which obviously covers physical and mental health, fatigue, wellbeing etc. – and so I wanted to start with an overview of the general demands of driving for work on the driver. We’re focusing generally on commercial vehicle drivers – so vans and trucks – and those drivers are probably doing reasonably high mileages across the year. So I was wondering if you could talk to us a little bit about what the general demands are for those of us who are largely office based and probably wouldn’t be aware of the demands on a commercial vehicle driver out there all day.

 

Lisa: Yeah, and that’s an important distinction, because a lot of people who are not driving for work really don’t understand some of the problems of actually driving a truck or a van, and some of the demands that drivers have. Often professional drivers complain about how the road users get in their way, and make things a bit more difficult for them because they don’t really understand things like turning circles, just being able to get around a corner and how they need to be considerate of what a big truck needs. So, yeah, there are a lot of stresses on professional drivers – not only just the type of vehicle that they’re driving, but also the nature of the work. What it is they have to do during the day. Some of the professional drivers have multi-drop kind of activities, others are long-haul, short-haul… it all varies. And they have to engage with customers and these are often quite stressful situations, especially if they’re running late. Management, supervisory practices… and of course there are a lot of issues around the traffic, and having to get through traffic to a tight schedule.

 

Simon: So I guess the main pressures sort of revolve around workload and time pressure. I often describe these when I’m talking to fleet operators, or warn them against creating unrealistic work schedules where it often doesn’t seem possible to make all of those deliveries, or all of those service visits within the expected time, without the driver having to speed or take other risks. So what does that kind of pressure… what sort of impact does that have on the drivers?

 

Lisa: Yeah. So, all drivers at some time or other will suffer from driver stress just because of the nature of driving these days. Traffic’s actually moving slower every year, so there are just general demands of the task itself. The work involved in manoeuvring a vehicle is actually quite resource intensive. And so, it can be quite high on workload. For example, the road environment itself represents quite a high workload – for example, if there’s poor visibility, or poor road markings or road surfaces. These are all things that professional drivers have to negotiate their way through, and it adds to the workload. And then, if they’re on a difficult route, or they’re having to perform difficult manoeuvres – perhaps having to park in very restricted areas… they also have a lot of different tasks to do at the same time. You know, thinking about work. And these kinds of situations mean that there are quite large fluctuations in the demands placed on professional drivers during the day.

So, the impact really can have a very negative impact on things like blood pressure and stress hormones – the research is… there are literally hundreds, if not thousands, of studies to show how driver stress can impact on these physiological measures.

 

Simon: Now, I know a lot of us talk to our delivery drivers when they turn up at home to gauge what kind of pressures they’re under. And following on from that last point, not only is excessive workload and time pressure really hard for them to cope with at times, but then many of them have their routes planned down to the very last minute. And so, if they encounter roadworks or congestion – those unexpected delays and diversions can probably really compound that, can’t they?

 

Lisa: Yes, that’s right. Whenever driving is externally paced and not self-paced, it becomes a demand. So professional drivers, delivery drivers, they often have performance targets to achieve. And, you know, if they’re being held up for whatever reason, then there are going to be impacts on the way in which they feel and how they tend to behave. So, for example, they’ll tend to get more irritable, more frustrated, more aggressive. And really develop quite an unpleasant, angry mood in some cases. And that can be quite difficult to deal with as another road user, when you see this quite hostile delivery van driver trying to get past you. And yeah, these are some of the everyday experiences that professional drivers have to go through I’m afraid.

 

Simon: Many drivers work odd hours, as well. Some of them have very long days, some of them are doing shift patterns, unsociable hours. And I know that one or two long days will do me in. Probably the same for most of us. So, how does that consistent, day-in day-out, long hours and unsociable hours – how does that impact on their general wellbeing?

 

Lisa: Yeah, there are very strong cumulative effects of fatigue, for example. The sort of, general wear-and-tear of doing this kind of job day-in, day-out, can have quite a terrible impact on their health. One of the first things that often goes when people are stressed is that they sleep quite badly – they can’t relax when they get home after work, they can’t switch off and have a good night’s sleep. And then, of course, stress itself is fatiguing. Because you’re operating the system at a very high spec, if you like. You’re trying to cope with all of these demands and that’s really quite fatiguing. So, yeah, there’s a general impact on wellbeing, such that there can be some really negative impacts on health.

 

Simon: And, it can sort of feed on itself, can’t it, then? Because if you’re taking stress from work home, and that’s causing you to sleep badly, you could have other areas where you’re bringing the pressures of home to work. Cases like those who have got a new baby in the house, or maybe have got financial worries, or other things. You’re bringing pressures to work, and the pressures of work are compounding it and going back home, and it just gets progressively worse.

 

Lisa: That’s right, and recently I’ve been looking into Post Traumatic Stress Disorder, which sounds like it’s a clinical condition that not many people have but, in fact, it mostly goes undiagnosed. And that’s a classic case of the chronic exposure to stress that can build up.

Let’s say, for example, you’ve had some very bad news at home, perhaps a close family member or friend has been diagnosed with a terminal illness or something of that nature. And then you have to go into this work environment where it’s quite stressful. It’s difficult because you’re going to be distracted by what’s going on at home and bring that into the work environment as a driver.

 

Simon: Yeah. I did a recent podcast on the increasing problem of drug driving, and how the police in many areas are now catching more drug drivers than alcohol. And actually, a lot of those turned out to be – in some cases, sort of half the offenders – turned out to be commercial vehicle drivers. So where we’ve got drivers experiencing these pressures, presumably quite a few of them are turning to drink and drugs as coping mechanisms for that stress. Which again, similar to the cycle of pressures building up between home and work, it’s a further destructive downward spiral, isn’t it?

 

Lisa: That’s right, and yeah, obviously these rather unhealthy coping strategies that commercial drivers might turn to – it’s sort of like a quick fix, if you like, to get you out of that state at that moment. You know, have a drink, have some kind of drug that would actually make you feel better. But, it is a destructive downward spiral because eventually, that will reduce your ability to actually handle stress in the long-term.

There are far better coping strategies that can be used to kind of offset the sedentary lifestyle nature of driving for work. Often we see that there are issues around diet and smoking as well as drugs and alcohol. So it’s about opening up other kinds of coping strategies that are much more effective.

 

Simon: Yeah, you mentioned
