- We estimate excess passenger weight in US transportation systems from 1970 to 2010.
- We determine excess passenger weight impacts on US transportation systems.
- We quantify fuel use, GHG emissions, and fuel costs due to excess passenger weight.
- Impacts for light-duty vehicles, transit systems, and passenger aircraft are studied.
- Since 1970, 1.1% of transportation fuel use has been due to excess passenger weight.

- 20 mph speed limits (and 30 kph limits) are increasing in importance as they roll out across the UK and Europe.
- Attitudinal support is high in the UK but there are concerns about driver non-compliance.
- Social marketing approaches may be helpful in influencing behaviour.
- Interventions may be best deployed across different segments of the population in different ways.
- A ‘diffusion’ model may be appropriate, in which ‘pragmatic’/mainstream drivers are influenced to conform because they perceive 20 mph limits as ‘normal’.

- Evaluation of a multicomponent intervention on active school transport (AST).
- Baseline AST, perceived route safety and attitude towards cycling was veryhigh.
- The proportion of active trips was 87% at follow-up with no intervention effect.
- Lack of effect was due to both incomplete implementation and high baseline level.
- A trend towards effect was seen for attitude and parental encouragement.

- Individual change and stability in walking and cycling is poorly understood.
- Retrospective methods offer a life course perspective on these behaviours.
- We present a novel application of a biographical approach on the topic.
- Longitudinal typologies reveal common and distinct trajectories of walking and cycling.
- Findings can inform policy to support life-long walking and cycling.

- We compare self-reported travel behaviour to objective data from wearable cameras.
- We examine journey mode and duration and daily summary travel frequency and duration.
- Results suggest excellent validity for self-reported mode of travel.
- Journey and daily travel duration have small biases at the group level.
- Journey and daily travel duration have very low reliability at the individual measurement level.

- Large differences exist in the volumes of travel by various groups in society.
- These differences are decreasing over time.
- There are large differences in access between urban and rural areas.
- Cultural factors contribute to differences in access.
- Casualty rates and vehicle emissions impact more on the poor than the rich.
