Design and Implementation of a Multiple Sensor Automated Warning System for Roadkill Prevention
7 Aug 2020
Design and Field Installation of Multiple Roadkill Prevention System Units under a Large-Scale Wildlife Safety Initiative
“Roadkill” is a serious threat to biodiversity conservation across the globe. Although various solutions have been proposed, most of them are inefficient or costly and complicated. Thus, with 1st round of RSG funding, an indigenous, multiple sensors based, low-cost, automated, partially wireless Roadkill Prevention System prototype has been successfully developed and tested. Now, the prototype needs to be configured for field implementation. Then it has to be monitored, while in action, for its impact analysis and to collect feedback data for its up-gradation. These activities; system configuration and implementation, monitoring, feedback collection, system up-gradation are aimed to achieve under this project phase.
Roadkill Prevention System
Present project work has set two fundamental goals A. Roadkill System modification/up-gradation B. Roadkill System field implementation and motoring.
A. System modification/up-gradation
Fallowing modification/up gradation has been planned under present phase of research and development work;
1. The system algorithm presently implemented is for relatively simple animal road crossing scenario which needs to be upgraded in to more robust form so that it can provide reliable warning in complex animal road crossing scenarios.
2. Adding memory unit to existing RPS to count number of animal crossing, time of crossing and their size statistics etc.
3. Alongside with present light based warning unit, Dot-matrix display needs to be added for displaying instruction to the passing vehicles.
4. Many challenges related system hardware are also planned to be solved;
a. How to convert present partially wireless system in to fully wireless without increasing cost significantly?
b. How to convert present night based system into day-night based system by changing/modifying the sensors?
c. How to incorporate remote controlled on-off condition?
d. How to add acoustic and ground vibration sensor (to catch animal call) and how to do relevant signal processing (segregating animal call from background noise)?
5. How to modify the overall design so that system cost can be reduced further?
6. Identifying potential applications of such low cost technology to some other similar conservation problem: as an example, to investigate whether multiple layer LASER fence of RPS can be re-engineered as automated animal crop raiding warning system or not.
B. System field implementation
System has to be field implemented and monitored for certain duration to understand its practical conservation impact as well as to collect feedback data for further system refinement in terms of algorithm, architecture and hardware. So, RPS prototype implementation and monitoring for 6 months have been planned to be executed under present phase of work (at list at two operation sites).
We are ready to freely share complete technology and provide every technical support to implement Roadkill Prevention system to any individual, group or organization at every other location wherever Roadkill is threat to biodiversity.
