Delta

A LUTI model captures the two-way feedback between land use and transport. Transport networks shape accessibility, which influences where households and firms choose to locate; those location choices change land use patterns and demand for travel, which then affect congestion, service levels, and future transport investment. LUTI models formalize this feedback to analyse current conditions and forecast outcomes under alternative policies. Delta endogenises these connections to provide a realistic simulation of urban change over time. 

Traditional transport models excel at forecasting travel demand, mode and route choices, and network performance under defined land-use assumptions. However, they are typically ‘static’ with respect to land use: accessibility changes are treated as outputs, not drivers of future location decisions. 

Delta adds what conventional models omit: 

• Dynamic land-use responses. Delta captures how accessibility shifts influence where households and firms choose to locate, how developers respond, and how these choices evolve over time. 

• Integrated markets. By modelling interactions across the property and labour markets, Delta links transport improvements to housing supply, prices/rents, job distribution, wages, and commuting patterns. 

• Long-term trajectories. Rather than a single snapshot, Delta simulates year-by-year pathways, revealing lagged effects, path dependency, and cumulative impacts. 

• Support Complex Business Cases. where land use and dynamic impacts are significance. 

SYSTRA provides the Delta modelling solution to simulate the relationship between infrastructure, housing, and jobs. It gives you the evidence needed to predict how transport projects will shape future land use and development. 

Yes. Delta is designed to be customized for regional contexts and requirements.  We tailor every deployment to your objectives. SYSTRA can provide a fully supported solution or integrate the analytical environment directly into your organisation for internal use.
