Demand

The Urban Strategy travel demand module is used to adjust transportation demand within an origin and destination (OD)-matrix using trip generation and attraction factors when new homes, businesses or facilities are built. A Furness method is used for trip distribution, balancing the number of trips to and from all zones.

New Mobility Modeller

The Urban Strategy mode choice module is used to (re)estimate mode choice (discrete choice model) for population groups by recalculating the utility per mode based on population characteristics (e.g. car ownership) and mode specific attributes (e.g. travel time and costs).

Traffic Assignment

The Urban Strategy traffic assignment module is used to assign all road-bound trips to the road network by use of a static deterministic multi-user-class (equilibrium) assignment. The model allows to assign modes trough an ‘all-or-nothing’ and/or ‘volume averaging’ assignment technique. The all-or-nothing technique assigns traffic between an OD-pair on the shortest path based on travel time. The volume averaging technique (re)assigns traffic during multiple iterations, with this technique the impact of congestion on route choice is taken into account.

Public Transport assignment

The Urban Strategy public transport module performs the allocation of passengers to a public transport network, taking into account how passengers travel from and to public transport stops given specified access and egress modes such as walking or cycling.

Air quality

The Urban Strategy air quality module calculates concentrations (e.g. NO2 , PM10 and PM2.5) emitted by traffic. Based on fleet composition, street type and congestion levels a grid of digital calculation points named ‘receptors’ calculate the air quality utilizing two standardized calculation methods SRM-1 and SRM-2 . In addition to emissions from traffic, background concentrations from other sources (e.g. industry, airports and so on) can also be taken into account.

Noise levels

The Urban Strategy noise quality module calculates the noise levels (Lden) emitted by traffic. The calculation follows the Dutch statutory method for noise calculations SRM-2
