Shared micro-mobility options are entering European cities, although at different rates. While the first insights about usage patterns, sustainability outcomes and equity effects start to accumulate, there is an emerging need for cities to develop a strategic view on the deployment of these new mobility options: How can shared micro mobility (SMM) options best be combined with existing transport systems to increase accessibility for all and add to sustainable transportation solutions? In this context, COCOMO aims to provide insights into: 1. How SMM are combined with existing travel modes within trips and longer term travel patterns and what implications this has for sustainability (VMT and greenhouse gas emissions); 2. How SMM interact with existing forms of travel in public space and how this impacts on the attractiveness and accessibility of these modes; 3. How travel implications of (see 1.), and access to SMM mobilities (see 2.) differ between geographical contexts and socio-economic groups, and what impacts this has on equity and inclusion. Based on these insights, COCOMO engages in co-creation with users and stakeholders in order to develop design and planning guidelines for sustainable and inclusive implementation of shared micro mobilities.

In Northern Ireland, an average person does over 80% of their journeys by car. This is very high compared to other parts of the UK, where 63% of journeys are made by car, and in Ireland, where the figure is just over 50%. Belfast is also one of the most congested cities in the UK. These problems are because too many people are driving too often. Being too reliant on our cars to get around leads to many detrimental impacts. For example, we walk and cycle less, our air quality worsens, and the number of road traffic collisions increases. It is, therefore, a growing issue in public health with more and more cities looking for solutions to help reduce our reliance on cars. However, solutions to such a problem are not simple as there are many different groups involved in or affected by the transport system. If we are to find policies and programmes that help reduce car reliance long term, then these groups must work together to solve the problem. Our project aims to co-develop sustainable and scalable policies and programmes that reduce the reliance on cars in Belfast. Our project is organised into 3 workstreams: 1) understanding the multiple layers of the system that influence the reliance on cars in Belfast; 2) exploring the current evidence and knowledge of what has worked in other cities; 3) developing possible policies and programmes with key organisations to reduce car use. Our policies and programmes are aimed at citizens who use their car for work, school drop-off, leisure and other activities in Belfast. But other road users will also directly benefit from less cars on the road, through less air pollution and fewer road traffic collisions. The general population will also benefit from cleaner air, less noise, and potential positive impacts on climate change. Our research includes the following steps: 1. We will undertake a survey using a technique known as Network Analysis to help us understand the network of stakeholders involved in the development, implementation and evaluation of programmes and policies to reduce car dependency and how they might best work together. 2. We will undertake a survey with road users in Belfast to evaluate and rank the importance of influences on car dependency and on alternative travel modes, using a technique known as Discrete Choice Experiments. 3. To develop agreement among stakeholders about the nature, ordering and relationships between programmes and policies of different organisations to reduce car dependency, we will develop visual diagrams of the 'system' of the various aspects that affect car dependency, using a technique known as causal loop diagrams. 4. We will host workshops with local citizens to 'sense-check' promising intervention approaches and policies to explore and ensure the acceptability, utility, affordability, feasibility and sustainability of new initiatives. Possible policies and programmes may include, for example: improved public transport, with the introduction of a new rapid transit system; investment in urban greenways to increase walking and cycling journeys; expanding the car-free areas of the city centre; extension of 'park and ride' and 'park and stride' facilities at the edge of the city. Our work will have the following outputs: 1. Identification of stakeholders influencing car dependency in Belfast and their relationships. 2. A review of the evidence for actions to reduce car dependency, leading to identification of possible new interventions and policies to be considered by stakeholders. 3. A map identifying ongoing and planned policies and interventions and their potential interplay. 4. A suite of potential co-ordinated policies and interventions 'tested' (in terms of acceptability and feasibility) with road users and local citizens. 5. A consensual understanding of the evidence provided and implications for reducing car dependency in Belfast. 6. A roadmap for multi-sectoral action to reduce car dependency in Belfast.

In the past four decades there has been a considerable modal shift from walking to school to going by car for primary school children in England. This has led to increased congestion and air pollution and decreased traffic safety. Meanwhile, many studies have shown the health benefits to children of active travel to school. The UK Government set a target to increase the percentage of children aged 5 to 10 that usually walk to school in England from 49% in 2014 to 55% in 2025. However, despite recent initiatives, such as the national Walk to School Outreach programme, the National Travel Survey in 2019 recorded the lowest ever percentage of primary school children walking to school at 46%. Time constraints are often cited as the main barrier to parents accompanying children in walking to school with concerns about safety deterring parents from allowing children to travel independently. This highlights that if a system of providing adult supervision for walking to school can be set up then there is good scope to increase the numbers of children walking to school. A walking school bus (WSB) involves a group of children walking to school with one or more adults and following a set route. WSBs have increased walking to school in Australia, New Zealand and the United States but the UK has not widely adopted them. Taking up WSBs in significant numbers requires a degree of organisation to establish meeting points, safe routes, adult supervisors and timetables. The proposed research will develop a planning tool to enable schools to maximise the number of children walking to school using safe routes accompanied by adults. At the heart of the tool will be an Optimisation Model that identifies walking routes to school and meeting points, while addressing multiple objectives (travel time, safety and air pollution exposure). We will develop this based on our extensive experience in developing multi-objective problem solutions for public transport scheduling and other transport and healthcare applications. The Optimisation Model will work in conjunction with a Modal Choice Model, which estimates student modal choices as input to the Optimisation Model, and with a Road Network Model, which estimates the consequences of a particular walk-to-school scenario on road network conditions. The Modal Choice Model will include a novel development recognising that decisions by parents on how their children get to school are based not only on individual considerations, such as minimising travel time, but on the opinions and choices made by other parents. This will build on the team's previous work exploring the role of social influence in travel choices. The Road Network Model will allow assessments to be made of traffic management measures that can be combined with WSBs to increase confidence in walking to school. We will design the tool so that it can be used repeatedly as circumstances change. It will be able to be used reactively for re-planning when there have been changes (e.g. children absent, new school years, etc.) or proactively to put in place 'ghost' routes/stops to attract new users where potential is identified (e.g. where there is a clustering of children or where WSBs can have maximum influence on reducing pollution near a school). Our aim is for the tool to support the work of organisations such as our Project Partner Living Streets delivering the Government's Walk to School Outreach programme. A Stakeholder Advisory Group will help steer the project. The academic team will partner with Living Streets to ensure the tool is well-grounded (for example, in terms of how parents perceive walking routes or how parents' willingness for their child to walk to school is affected by physical and social context) and is practically useful for real-world application. We will demonstrate the planning tool in Bradford where the local authority and schools have agreed to work with us in designing and applying our work.

The UK transport sector lags behind all other sectors in its achievement of energy diversification and carbon emission reductions to date, with emissions from transport essentially unchanged since the benchmark year of 1990. The Committee on Climate Change have been very critical of this failure and identified electrically-assisted scooters and bikes as part of solutions that need to be urgently accelerated. Indeed, the UK lags behind other countries in the uptake of a range of innovative light vehicles for both passenger and freight applications. Examples include electrically-assisted: bicycles, cargo bicycles, push scooters, skateboards, trikes, quadricycles, hoverboards etc. These involve some electrical assistance, as well as some energy expenditure by the user. Hence, we class these vehicles as light electric vehicles for active travel (LEVATs). They enable people to cycle, scoot, skate or otherwise travel more easily or enjoyably than conventional walking or cycling. Their power source provides the opportunity to link to a variety of digital technologies - from unlocking shared vehicles, to 'track-and-trace' systems for delivery companies, to map systems or health feedback tools for users - what ELEVAVTE refers to as 'digital' travel. Innovation at the interface of e-mobility and digital technologies plays a key role for the uptake of these novel modes, with energy, IT and transport industries as key players. Increased uptake of these vehicles has significant potential for reducing mobility-related energy demand and carbon emissions, especially when users switch from non-active modes such as cars or vans. The aim of this project is to better understand these opportunities - the technological and business options and specifications, where and who they might appeal to, what trips they could be used for, how far they could replace conventional motor vehicle trips - and some of the challenges that accompany them - such as overall energy usage, safety and regulatory issues, digital integration, physical environment design, battery standardisation and behavioural inertia. After developing typologies and technology assessments based on multiple criteria, the empirical end user research will consist of surveys (aiming for 1,200 responses), demonstration days (aiming to engage at least 300 people) and longer trials with at least 60 private individuals in 3 cities in England throughout 2020 and 2021. Quantitative surveys and in-depth interviews will be undertaken with participants before and after usage to understand changes in user perceptions and experience, triangulated with GPS tracking of the trial vehicles and contextual data (e.g. weather, hilliness). As part of the work, we will develop new safety training resources for each mode, drawing on, and adapting, existing UK initiatives and international experience and working towards certified schemes. Freight applications in the logistics industry will be analysed through expert interviews and case studies. A number of technology and demand scenarios will assess the whole lifecycle health and environmental impacts. This will include work with the World Health Organization expert group to extend the HEAT tool (which enables users without expertise in impact assessment to conduct economic assessments of the health impacts of walking or cycling) to include these types of vehicle. This project is supported by a range of partners - including the three local authorities, Sustrans and the World Health Organization - and will be guided by an advisory panel. We will also engage with a range of industry stakeholders, through the Transport Systems Catapult, Clean Growth UK and other means. We also envisage international engagement in the work, given the rapidly evolving and growing nature of the topic, and the lack of a substantial academic literature on the implications of these innovative light vehicles for energy demand, mobility and climate change.

Domestic transport is the UK's highest emission sector, and congestion in cities is costly (e.g. London £5.1bn in 2021). Drastically reducing urban car dominance is imperative to reach the UK's 2050 net-zero target, but also an unparalleled opportunity to create more equitable, inclusive and accessible cities of the future across the country. Recent UK investments of approximately £15bn seek to radically transform urban mobility and modality: £2bn for half of urban journeys to be cycled/walked by 2030 (e.g., cycle lanes, mini-Holland schemes), £5.7bn City Region Sustainable Transport Settlements (e.g., Manchester bus and cycle schemes), and £7bn to level up local bus services. To realise full investment potential, and develop holistic adoption pathways towards net-zero, inclusive mobility, multimodal transport must be effectively planned, managed and operated, with people and their differences as a core consideration. This is challenging for a complex system-of-systems. On the supply side, modes compete for limited road space on shared infrastructure, creating conflicts. On the demand side, modes complement each other in intermodal journeys, jointly influencing uptake. For example, cycle lanes promote cycling, but may impact road speeds and exacerbate congestion and pollution, highlighting the need to evaluate person-level mobility and system-level emissions. A recent survey reported two-thirds of disabled respondents finding cycling easier than walking, highlighting the need to consider the broad disability spectrum and the potential for cycle lanes to improve access for all. Therefore, holistically optimising cycle lane schemes, as with all multimodal schemes, requires integrated methodologies: fully capturing multimodal transport systems' distributed and interconnected processes, the complexities of modal competition and complementarity, and the heterogeneity of traffic and population. My research will overcome these research challenges and develop the first multiscale digital twin for the transport-people-emission nexus using a truly integrated approach to model and simulate multimodal urban transport, advancing and coalescing my adventurous research in multimodality, using traffic flow theory, agent-based modelling, and machine learning. This will enable the development of holistic adoption pathways towards net-zero, inclusive mobility through scenario testing and optimisation, with guidance and recommendations to support implementation. Leading a strong consortium of 3 cities and 12 partners, covering the entire multimodal transport value chain, I will collaboratively exploit the digital twin to realise UK strategic agendas: net-zero; Equity, Diversity and Inclusivity (EDI); and levelling-up. By holistically enhancing mobility for everyone, my Fellowship also will propel the Green Revolution for economic growth, leveraging the net-zero mission to unlock new business opportunities, and establish the UK as a global leader in digital technologies to tackle climate change. I will deliver a strong positive impact on making net-zero a net win for people, industry, the UK, and the planet, thereby enabling both me and the UK to become world leaders in multimodal urban transport, at the forefront of research and innovation.
