Analysis of pedestrian congestion

A computer system for determining an increase in a walking pattern of a pedestrian to avoid obstacles on a path along which the pedestrian is walking, the computer system comprising:

• a plurality of transceivers on the pedestrian to generate data relating to the walking pattern of the pedestrian on the path, the plurality of transceivers including a primary transceiver on a first foot of the pedestrian, and a secondary transceiver on a second foot of the pedestrian;
• and
• said plurality of transceivers being configured for measuring, over time, distances between feet of the pedestrian;
• and including,
• the primary transceiver transmitting a train of pulses PI at a frequency FI, and starting a timer
• count T at each of selected ones of the pulses,
• the secondary transceiver, upon receipt of one of the pulses PI from the primary transceiver, transmitting, after a fixed time delay t, a series of pulse P2 at a frequency F2,
• at each of a multitude of times, the primary transceiver, upon reception of one of the pulses P2, recording a timer count T, and re-starting the timer count T at the next one of the pulses P1,
• using the timer counts T and the time delay At to determine a multitude of the distances d between the feet of the pedestrian, and
• using said determined distances d to determine an increase in a distance the pedestrian walks on the path to avoid the obstacles.

A computer readable program product comprising:

• a computer readable medium having a computer program code tangibly embodied therein for determining an increase in a walking pattern of a pedestrian to avoid obstacles on a path along which the pedestrian is walking, the computer program code, when executed in a computer system, performing the following:
• receiving, at the computer system, data from a plurality of transceivers on the pedestrian data relating to the walking pattern of the pedestrian on the path;
• and
• using said transceivers, over time, to measure distances between feet of the pedestrian;
• and wherein
• the plurality of transceivers include a primary transceiver on a first foot of the pedestrian, and a secondary transceiver on a second foot of the pedestrian;
• and
• the using said transceivers, over time, to measure distances between feet of the pedestrian includes
• the primary transceiver transmitting a train of pulses PI at a frequency FI, and starting a timer count Tat each of selected ones of the pulses,
• the secondary transceiver, upon receipt of one of the pulses PI from the primary transceiver, transmitting, after a fixed time delay t, a series of pulse P2 at a frequency F2,
• at each of a multitude of times, the primary transceiver, upon reception of one of the pulses P2, recording a timer count T, and re-starting the timer count T at the next one of the pulses P1,
• using the timer counts T and the time delay At to determine a multitude of the distances d between the feet of the pedestrian, and using said determined distances d to determine an increase in a distance the pedestrian walks on the path to avoid the obstacles.
