City Mobility
Simulator

A high-performance digital twin solution
for city-scale transport systems

What is CityMoS

CityMoS, the City Mobility Simulator, is a high-performance, multi-core, agent-based, microscopic mobility simulator capable of simulating city-scale transport systems at high resolution, including private, public, and commercial transport. CityMoS has been and can be used to support the transition to electric vehicles, the design of novel intelligent transport system solutions, the introduction of new modes of public transport, or the mitigation of traffic emissions such as carbon dioxide or heat. Contrary to existing traffic simulators, CityMoS focuses not only on traffic patterns but on the mobility of individuals, that is, trip chains, activities, and mode choices.

Why Choose CityMoS

CityMoS utilises a modern computer science approach to push back the frontiers of microscopic simulation by balancing accuracy, scalability, and performance.

ACCURACY

CityMoS includes many participants of the transport system, private vehicles to public transport. Advanced models for motion, comfort, energy, and safety grant detailed and holistic insights into the performance of the transport system.

SCALABILITY

Unlike other high-detail mobility simulators, CityMoS can simulate mobility at city and state scale. This enables insights into how local changes can have system-wide effects. CityMoS also delivers high-fidelity results for large-scale highway networks.

PERFORMANCE

CityMoS does not require expensive supercomputers to provide performance. It runs on consumer hardware to master challenging simulation scenarios. Results for an entire week of large vehicle popula-tions are ready in only a few hours.

Hear from our Collaborators

CityMoS helped us to optimize the operational KPIs of autonomous electric vehicle fleets in public transport systems. Its capabilities are unique in the market, offering a wide variety of functionality from microscopic to macroscopic transport planning tasks. It is easy to use and facilitates insightful conclusion through comprehensive reporting.

The multi-year research collaboration between the CityMoS team and myself has been one of the most rewarding experiences during my stay in Singapore and beyond. Our work has been focused on modeling drivers’ behaviors in a mixed autonomous-human driving scenario and has extended the capabilities of CityMoS for the development and testing of autonomous driving algorithms and the study of traffic congestion effects. Looking forward to many more years of collaboration!

It was a great experience working with the energetic CityMoS team to develop high-performance solutions and witnessing its development over the years. I'm so happy to see that the CityMoS now has become a full-fledged mobility simulator with an array of features and has been used in developing so many applications.

APPLICATION AREAS

Holistic Transport System Evaluation & Exploration

Analysing Private, Public, and Commercial Transport

  • Extracting metrics that may not be accessible in the real world such as travel times, waiting times, change of transport mode, energy consumption, etc.
  • Studying the effect of alterations to the road network such as adding or removing roads, changing speed limits, varying traffic light programs, etc.
  • Simulating extreme events such as accidents, road blockages, and increased traffic caused by special events

Detailed Public Transport Simulation

  • Testing the effect of different schedules, headways, or vehicle capacities
  • Studying the impact of new bus lines, railway lines, or completely new
    modes of transport
  • Analysing and mitigating effects such as bus bunching or unmet
    passenger demand

APPLICATION AREAS

Greener Transport Systems

Transport System Electrification

CityMoS can analyse spatiotemporal energy consumption and charging demand. CityMoS supports the planning of charging infrastructure, resources, and incentive policies. It can also help strategize the electrification of the public transport system by identifying the bus lines which can be electrified and the impact of taxi/private hire car fleet electrification.

Environmental Aspects

CityMoS can also be used to accurately study mobility-related environmental parameters on a city-scale such as fuel consumption, emissions of pollutants (e.g. CO or NO ), and heat caused by traffic. Additionally, CityMoS also serves as a simulation tool to study the impact of alternative fuels such as hydrogen to support more sustainable transport.

Holistic Analysis

CityMoS can be integrated with other models to study the effects of, e.g, weather or complex human behaviour. It can be coupled with other software such as power systems simulators. This enables CityMoS to examine if the underlying electric grid can support the demand caused by electric vehicles, and in turn support charging infrastructure planning.
