Quadstone Paramics provides a realistic representation of the "friction" to traffic flow caused by pedestrians. Our simple to use pedestrian modelling system allows users to obtain meaningful results quickly, ensuring a realistic model is developed within the minimum amount of time and resource. In Quadstone Paramics, our pedestrians are free space agents; simulated people who can move freely within the study area defined by the user.
Paramics can be used to determine if there is the need to provide a new crossing facility by evaluating delays to pedestrians, probability of conflict between vehicles and pedestrians and the queuing / packing pedestrians are subjected to while they wait to find a suitable opportunist crossing gap.
If the need for a dedicated crossing facility is proved Paramics can also be also be used to evaluate how different types of crossing and different Walk / Don’t Walk times affect traffic flows resulting in longer queues and more delays to drivers. Paramics can be used to perform balanced urban space design where the needs and quality of service provided to both vehicular and pedestrian users are evaluated in tandem.
Un-signalised pedestrian crossings can be modelled using a combination of shared and vehicle aware space. Depending on the type of crossing, different types of shared space can be used to make vehicles yield to agents waiting to cross or to aggressively move through the shared space interacting with agents.
Signalised pedestrian crossings can be modelled using combinations of shared and vehicle aware space as above but additional control can be added using blocking regions connected to selected phases of signalised intersections. A typical example of an interrupted right turn would use aggressive shared space and blocking regions tied to either a fixed or call on demand phase at the signalised intersection.
