1. Questions
Employer-led mobility management research and practice focuses almost entirely on the commute, and its instruments are designed to move employees out of the private vehicles they use daily (Chen and Yang 2023; Roaf et al. 2024). Work-related trips undertaken for a public authority within the city differ in kind, since the employer sets the destination but rarely the mode. Such trips remain poorly documented. Research on work-related travel concentrates on long-distance business journeys (Jittrapirom et al. 2025), and studies that classify such travel by spatial scale find local trips within a city the least examined (Hislop 2016). National travel surveys that do record professional travel separately still pool it with commuting in analysis (Hogeweij et al. 2026).
Athens, a compact and heterogeneous historic European city, is well suited to studying such trips. The municipality covers 38 sq. km, served by three metro lines, a tram and a dense bus network. Its municipal buildings stand close together, a median of about 300 m apart, with 78% of all pairs under 4 km and six in ten within 500 m of a metro or tram stop (Figure 1). Not every directorate has a vehicle.
The survey asked how far employees will walk before changing mode, and whether conventional workplace mobility management has anything left to act upon. Earlier research places the acceptable walking distance between 400 and 800 metres, although recent evidence indicates that people walk further (Merlin et al. 2021; Taylor and Somenahalli 2024; Yang and Diez-Roux 2012).
2. Methods
An anonymous questionnaire ran from 23 November to 28 December 2023 within the Walkable Athens programme (https://walkable.cityofathens.gr). It was sent to 34 service mailboxes in five directorates whose staff work in the field, each reaching five to ten people, so roughly 170 to 340 employees were addressed directly. Sixty-five replied, and the 62 who answered all three distance items form the analytic sample. Thirty-six belong to the directorates addressed directly, an indicative response rate of 11% to 21%. The remaining 26, from other departments, received the link from colleagues, so their response rate is unknown.
Respondents reported how often they are sent out, whether they carry heavy objects and how they would travel at 500 to 800 metres, 800 to 1,500 metres and 1.5 to 4 kilometres, giving their two main reasons from a list including time, load, terrain, weather and health. The bands start within the usual 400 to 800 metre walking threshold, since the survey asked how far employees will walk before changing mode. The three mode items (Q12, Q14, Q16) listed all modes and allowed multiple answers, but only the commuting item (Q6) added that several modes may be ticked “where they are of roughly equal weight in the trip”. A short walk to the metro may therefore have gone unticked, and the shares walking at all are a lower bound. Only one respondent chose cycling for errands, as Athens has no continuous cycle network or public bicycle scheme. Cochran’s Q tests whether the share of a mode changes across the three distances, McNemar’s test compares commuting with errand modes, and Fisher’s exact test compares two groups of respondents. Shares carry 95% Wilson confidence intervals, which remain reliable for small samples and near-zero shares.
3. Findings
No respondent would use a private car at 500 to 800 metres, 3% would at 800 to 1,500 metres and 10% beyond 1.5 kilometres (95% interval 5% to 20%), although 20 of the same respondents (32%) drive or are driven to work. Of these 20, none would take the car for the shortest errand and four for the longest (Figure 2, McNemar’s test, p < 0.01 in every band). Instead, most would walk or take public transport. Moped commuters behave differently. Of the ten who ride a moped to work, six, seven and nine would also use a moped for errands at the three distances, and none would use public transport.
Walking and public transport carry these errands (Figure 3). Walking the whole way falls from 68% in the shortest band to 37% and then 6% (Cochran’s Q = 55.5, p < 0.001). Walking at all declines more gently, from 87% to 60% and 34%, while public transport rises from 15% to 34% and 53%, so walking partly becomes the way to reach public transport rather than disappearing.
This decline holds in every subgroup of at least eight respondents (Table 1). Walkers cite time saving no more often than others, 66% against 75% in the shortest band and 57% against 69% in the middle one (Fisher’s exact test, p = 0.563 and 0.411). At short range, a municipal vehicle was chosen only by employees who carry heavy objects, three of 15 against none of the other 46 (p = 0.013), while terrain and weather were rarely cited (3% and 7%).
Car-reduction policy therefore has little to act upon, and the better measures support the walking and public transport already carrying these errands. Rewarding those who walk or use public transport draws broad support (median 10 out of 10, Table 2). The incentive item, addressed to the 29 employees who reach work by car or moped, was answered by 25. A shorter working day (36%) and a subsidised annual transport pass (32%) were chosen about equally often, ahead of a municipal shuttle bus and extra annual leave (16% each). Combining a one-hour shorter working day with such a subsidy would offset both the time and cost of commuting by public transport and act as a commuting benefit (Roaf et al. 2024).
Four limitations apply. The sample is small and not random. Comparing each respondent with their own answers rules out differences between people as the source of the decline in walking with distance, but not bias in who replied. If employees who already walk or use public transport were more willing to reply, car use for errands would be understated. Respondents described single errands at fixed distances in ascending order, without origin, destination, extra stops or personal tasks, and none under 500 metres, so these thresholds are perceived rather than observed. The fieldwork ran in late autumn, and although work-related travel resists heat better than other purposes (Hogeweij et al. 2026), Athenian summers are far hotter. Future work should follow actual errands with GPS or travel diaries across seasons, including short trips, extra stops and the vehicles municipalities provide.

The programme received ethical approval under protocol 50736/27.10.2020, and participation was voluntary and anonymous, with no personal identifiers collected.
