Staff Travel Survey

Draft Report March 2008

Confidential Executive Summary

This report presents the findings from a staff travel survey conducted at University between 29 October – 9 November 2007. A total of 752 responses were registered in the on-line survey (18 of which were completed via the paper survey). After data cleansing for incomplete responses and duplicates – a total of 741 returns were recorded, representing a 42% response rate.

75% of staff travel to the University 5 days a week. The average journey time (regardless of mode) is 30 minutes door to door.

In a typical week, 79% of staff travel to and from work by car. Of this figure, 70% of staff who drive to the University do so as a single occupant. 48% of staff that live within a one-way trip distance of 1-3 miles are driving as single occupants. Car driving becomes more dominant by distance although a significant proportion travel by car at distances of up to 6 miles.

Staff who drive to work do so for reasons of convenience over public transport, flexibility, speed and distance of travel. Most staff (93%) who drive to work park in a University authorised car park.

Public transport, walking and cycling account for only 20% of staff travel.

Staff rate public transport frequency and reliability as the highest priority transport options.

Introduction

This report presents the findings from a staff travel survey conducted at from 29 October – 9 November 2007. This report contains summary frequency data for all the survey questions and selected text data.

The survey utilised was designed by the HEFCE funded Higher Education Environmental Performance Improvement project (see www.heepi.org.uk for further details). It was developed by several Universities and to date has been used to survey staff at 18 institutions1.

Designed specifically for the education sector, the survey has the following benefits:

Ø Electronic and hosted on an external server Ø Off the shelf package offered at cost Ø Possibility to alter survey to suit local parameters i.e. site specific names Ø Allows benchmarking of performance through standardised questions Ø Allows institutions to quickly and effectively survey staff and students

The survey was conducted to support the implementation of a University Travel Plan and associated environmental improvements at the University.

Methodology

Details of the electronic survey including the url, password, incentives and need to survey were advertised to staff by a variety of means including:

Ø Information posted to HSEU website 29/10/2007 Ø Email sent to University Green Group members 29/10/2007 Ø Information posted to Environmental Forum 29/10/2007 Ø Notices posted on 'All Staff' on 29/10 & 07/11/2007 Ø Email sent to all staff inboxes on 30/10 & 05/11/2007

In addition, a further 153 paper copies of the survey were printed and distributed to professional support staff within Estates and Hospitality and Leisure Services. This data was entered manually into the online survey.

The survey was hosted on a 3rd party server. The data was exported into excel, checked for duplicates, errors or empty records and a final data set was then analysed using basic descriptive statistics. The descriptive statistics and text data from the initial analysis are included in this report. Variations in response rate for individual questions or parts of questions are attributed to some respondents not completing the full or part of a question. All values in the table are reduced to one decimal place which may lead to slight discrepancies against the totals which have been kept at 100%.

1 Between 2003 – 2007, with 8 of the Universities also surveying students. Findings

Sample size and characteristics

A total of 734 responses were registered on-line with a further 18 completing the paper survey (which were manually entered into the online survey), making a combined total of 752. 11 entries were stripped from the sample as these were deemed to be either incomplete responses or duplicate entries. Not all staff responded to every question.

741 complete entries equates to a 42% response rate. Numbers of staff per employment category for December 2007 provided by the Personnel Department can be found in appendix one.

Age & Gender

The survey sample was broadly representative of the gender split at the University. In the survey the female to male split was 57% / 37% (6% not specified) compared to 59% / 41% of the total staff population at the University.

Time spent travelling

Around a third of staff (32.3%) travel for 16-30 minutes door to door. 33.8% of journey times to work on the day of the survey took more than 31 minutes with 5.3% lasting more than an hour.

Car Drivers

Parking

92.6% of staff that drove parked at a University owned car park. This high figure is not surprising given that the University does not control or charge for parking.

The questionnaire was designed to route those who drove to the University on the day of completion through to a section specifically about driving and parking.

Insignificant numbers of staff (1.7%) park their cars outside of University owned car parks, although 5.7% of staff park in ‘other’ areas. An element of this may include those staff that were car share passengers resulting in the vehicle going on to a forward destination.

Reasons for using car

Staff that drove on the day of the survey were asked what their main reasons for travelling via the car were. The prime reasons for doing so are: lack of convenient public transport (327), speed of the car (303) and the increased flexibility the car offers (250).

Reason2 Staff responses I need to use my own car for University business 144 I use my car before/during/after work for non-University business 165 Alternatives forms of travel aren’t safe 37 I use the car because I have a disability or other health reasons 26 Its cheaper to use the car than public transport 112 There isn’t a convenient public transport service 327 I provide others with a lift 55 Its quicker to travel to the University by car 303 I prefer the comfort and privacy of travelling by car 155 I can park cheaply at/close to the University 119 Its too far to walk/cycle 209 Its too hazardous or unsafe to walk/cycle 127 I don’t have enough information about alternatives 15 I have to carry books/equipment 139 My car provides more flexibility 25 I have childcare commitments (e.g. school, nursery) 112 Other 51

Alternatives to the car

30.4% of car drivers stated they did not have a feasible alternative to driving to work on the day of the survey.

For the remaining car drivers, the bus (21%), train (15.5%) and car sharing (14.4%) are the most popular alternatives.

Respondents were asked to indicate how many car business miles on average per month they travel, the average being 167 business miles per month (based on 407 responses). The maximum travelled per month is stated as 5,000.

Travel Viewpoints

A set of possible travel policy options were presented in the survey and respondents were asked to indicate the level of importance that should be placed on each policy in relation to the University Travel Plan. Most notably:

· Staff rate more restrictive / expensive parking on campus as the most unimportant travel policy. Surprisingly though, only 26.6% (197) of staff feel opposed to this · More reliable and more frequent transport routes are also of high importance to staff, 50.6% (375) and 42.6% (316) respectively

Highest Priority Travel Plan Measure

Respondents were then asked which they felt of the above options should be given the overall priority when developing the Travel Plan. The policy alternatives that received the highest level of support in terms of % indicating highest priority are:

· Encourage and support more people working from home - 24.7% (183) · New public transport - 8.9% (66) · More reliable public transport – 8.2% (61)

Attitudes to travel policy options and issues at University

One of the final questions of the survey offered respondents the opportunity to comment on aspects of current transport and travel provision and issues at the University. This generated a large volume of responses. The raw text data is found in appendix three.

A large majority of comments however fell under four broad categories:

· Policy and Planning · Parking – costs and facilities · Public Transport cost, reliability and frequency · Cycling

Some of the key statements made by staff are summarised below:

Overall Policy Planning

“…In general initiatives such as this are poorly thought out because they are developed in isolation and are more focused on having an 'acceptable' policy rather than recognising that it is a balance between many competing pressures…”

“… is not a town centre campus and its links to the town are fairly poor. The Weston Road is particularly congested and I often walk faster than cars drive along. I sadly have to breathe their emissions…”

“…I think bonuses should be given to people accordingly for how they travel to work…”

“…Need to support alternative travel arrangements while not penalising those whose multi-site activity is essential...”

“…The University used to have a travel centre and you could get a reduced travel pass for staff. This should be re-introduced to encourage more staff to use public transport…”

Some staff feel unsafe and anxious when travelling to and from the campus

“…it’s dangerous to park at leek road when you leave late at night…”

“…staff who work late and leave eg 8pm feel vulnerable when walking back to their vehicles…”

“…When it is dark I do not feel safe walking home from the University…”

“…I finish at 9.00pm on a Tuesday and leaving the building and walking to the car is not always pleasant. Two weeks ago I had the windscreen wipers stolen from car in the staff car park…”

Many staff are unhappy with current car parking provision at Staffordshire

“…Car parking on all University sites is now inadequate for the number of users - but this should not be used as an argument for more car parking space (which is 'dead' space). Instead we need to have fewer cars on campus…”

“…The parking in the College Road car park is terrible. People park all over the pavements getting in the way of pedestrians even when there are spaces free. It would be useful if some kind of policing took place to stop this happening…”

“…Charge for parking in university areas - through staff / student pass only system - doesn’t need to be too expensive but mandatory. Visitors need to pre-registered or are sanctioned through the university (free day- pass). Set aside some 'free’ short-stay parking…”

“…I would find it extremely unacceptable to have to pay to use a car park at my place of work…”

“…I find it extraordinary that the university has not instigated a clear and fair charging policy for on campus parking. 15 years ago when I studied and worked at Warwick University parking charges were introduced…”

“…Clamp down on public use of university car parks (particularly Leek Road site) Refuse entry to campus for vehicles not registered. Clamp down on illegal parking (parking on double yellows and outside marked parking bays)…”

“…Car parking can be chaotic. Security staff appear to make up the rules on the hoof. Too many cones restricting genuine staff from parking…”

“…I would support charging for car parking at Leek Road (in particular) - especially if it helps to discourage parking on the grass or on yellow lines. There also seem to be a number of non-university users of Leek Road car parking…”

“...Perhaps if more car parking was available specifically for residential students they may be more inclined to leave their car and walk onto campus. I have seen many students drive what would be a 5 minute walk...”

“…Our big issue is that students want car parking (so we need it for recruitment) and we don't have space for everyone to park. To thrive therefore we need to discourage staff car use to promote parking for students…”

“…Current parking arrangements are a nightmare! Why are students in Stafford Court allowed to DRIVE to the Beaconside campus??”

“…Increased free car parking capacity should be a major consideration for the university as it expands…”

“…In the past insufficient attention has been paid to travel/parking issue when developing university sites. Renting out university car parking spaces to other organisations doesn't help!”

Bus and train services in Staffordshire are experienced or perceived as slow, expensive, unreliable, infrequent

“…the unreliability of trains coupled with the high costs of them means it is not practical…”

“...It takes me 20 minutes to drive to University. Or 1 hour 10 minutes and 2 buses…”

“…I used to come on the train every day and then cycle to the campus; this was stopped purely as the train was more expensive and was late most days…”

“…I would have to catch a bus and a train each way so each journey would cost me far too much money…”

“…I would need to change trains twice so the train route is too inconvenient and, whenever I use it, is unreliable…”

“…I do feel that train travel needs to be made a more financially attractive alternative to compete with cars…”

“…The Baker bus needs to leave AFTER the hour not ON the hour. The Baker bus should not go on the A500 where there are no bus stops. Consideration should be given to transport (Baker buses) between sites for evening lectures & those who work late…”

“…Working from home should be encouraged - it can easily be done when required…”

Cycling

“…there are no facilities to encourage students to use the local cycle network. Back 2 Bikes in Stafford, a charity, sells 2nd hand bikes fully safety checked from £15…”

“…Could the university provide cheap/interest-free loans for staff to purchase bicycles?”

Cycling/Walking Facilities

“…Need cycle park and cycle paths. One student I spoke to thought bikes were not allowed on campus...”

“...Need safer road crossings around University site especially Beaconside...”

“…I have recently started to ride a bicycle but due to the lack of cycle lanes I don't feel confident and safe enough to use it to travel to work. There also needs to be shower facilities on the College Road campus…”

“…Facilities for cyclists are woefully inadequate. We should be encouraging more people to cycle to work…”

“…Having access to showers following a cycle ride/ walk/ jog to work would be great…”

“…It would be really useful to have shower facilities within the faculty itself for if people cycle - I have cycled in the summer and found it ok but only because there were no students in to smell my sweat!...”

“…Take some of the absurdly disproportionate space allocated to car parking and make secure cycle accommodation a priority not an after thought…”

“…If better facilities were available I would cycle into work on the days I didn't need to travel…”

“…The lack of bike sheds at Beaconside is dismal. Seeing students damaging trees to fasten their bikes due to nowhere else to put them is a shame…”

Cycling/Walking can be seen as dangerous and impractical in Staffordshire

“…Cycling and walking are perceived as dangerous because bad and aggressive driving is not prevented…”

“…Road design in Stoke makes cycling highly dangerous…”

“…Although I live only a few miles from the university there are no footpaths on part of the road. This would be potentially dangerous for pedestrians especially during the winter months…”

“…I am from a one car family and find it too hazardous to walk to walk as there is no allocated footpath - I attempted to walk once but it is far too dangerous hence my use of the car!”

“…I have recently started to ride a bicycle but due to the lack of cycle lanes I don't feel confident and safe enough to use it to travel to work…”

“…Should be a pedestrian crossing on the Beaconside road near the University's road exit. The current situation is very dangerous for students crossing over unassisted as the road speeds can be quite high and the roundabout is very busy...”

Motorcycles

“…I would like to see better motorbike parking…”

“…Better and more facilities need to be provided for parking of bicycles motorcycles and scooters. The campuses favour car use by providing many parking spaces for cars - bike users feel they cannot use these spaces as they would be taking up a car space…”

“…Improved motorcycle security would be a big bonus - there are ground anchors installed in front of Trent but these are not convenient...”

Intersite Travel

“…The free intersite bus service should have been kept…”

“…The main problem about using the bus between Stafford and Stoke for me as a senior manager is the length of the journey and the frequency of the service. This can turn what would take a couple of hours (including a meeting) into 4+ hours…”

“…The loss of the free inter-site mini bus has had a significant impact on student attendance…”

“…Travel is often unnecessary if meetings could use video conferencing instead…”
