01 / PRODUCT OVERVIEW
Choose a place that works across many starting points.
“What is nearby?” is easy for one person. It becomes a decision problem when friends, customers, warehouses, or facilities begin from different locations.
THERE combines place discovery with route-duration comparison. It gathers candidates around the supplied origins, evaluates travel time under the selected trip conditions, and presents strong shared choices in a form people can inspect and use.
My roleProduct Designer · Lead DeveloperProduct concept, decision workflow, Google API integration, travel-time analysis, R Shiny interface, and map-based delivery.
02 / USER WORKFLOW
From several origins to a practical shortlist.
The interface keeps the decision sequence explicit: define the search, set trip conditions, run the comparison, then inspect the recommended places and their travel-time implications.
- 01
Connect the services
Enter a Google API key with Places, Directions, and Geocoding enabled. The interface states that the key is not stored.
- 02
Define the search
Choose a place keyword, add multiple origin addresses, and optionally filter for places that are open now.
- 03
Set trip conditions
Select driving, walking, bicycling, or transit and set the relevant departure date and time.
- 04
Find shared options
THERE searches nearby candidates around the origins and compares travel time from every origin to every candidate.
- 05
Review and act
Inspect recommended places, trip-duration tables, ratings, addresses, Google Maps links, and the Leaflet result map.
03 / DECISION LOGIC
A transparent geospatial and travel-time pipeline.
The source code exposes the complete path from addresses and place keywords to ranked options, trip-duration tables, and the result map.
Candidates02
Search nearby places
Query Google Places by keyword, radius, open-now status, and price settings around each origin.
Travel matrix03
Calculate route duration
Use Google Directions to calculate time from every origin to every candidate for the chosen mode and departure time.
Decision output04
Rank and visualize
Surface candidates that repeatedly appear among the closest options, then return duration tables and a Leaflet map.
04 / EXTENDED VIDEO DEMO
Full product walkthrough.
The demonstration shows the live Shiny workflow, including search inputs, multiple addresses, recommendation outputs, and map-based review.
05 / USE CASES
One workflow for shared plans and location decisions.
Find a shared destination
Compare restaurants, stores, or other searchable places for a group whose members start from different addresses and may use different trip conditions.
- Multiple participant origins
- Keyword and open-now filtering
- Inspectable travel-time tradeoffs
Compare candidate service locations
Screen retailers, supermarkets, shipping services, or other facilities relative to warehouses, plants, customers, or operating locations before deeper site analysis.
- Origin-to-candidate route matrix
- Ratings, addresses, and map links
- Exportable result tables
06 / TECHNICAL ARCHITECTURE
R-based analysis delivered as an interactive web application.
R Shiny
A responsive navbar application coordinates API-key entry, search controls, dynamic address inputs, settings, tables, and maps.
Google Places + Geocoding
Address autocomplete and geocoding establish the origins; nearby place queries retrieve candidate destinations and metadata.
Google Directions
Route durations are calculated across the origin–candidate matrix using the selected mode, departure setting, and traffic model.
Leaflet + DT
Interactive mapping distinguishes input origins and discovered places, while searchable tables expose recommendations and trip durations.
07 / ROLE & TECHNICAL STACK

08 / AVAILABILITY & DATA USE
Try the live app or inspect the full source.
THERE requires a user-supplied Google API key with the necessary services enabled. The interface states that the key is not stored; Google API quotas, billing, data practices, and service terms still apply. Use the results as decision support and validate important location choices independently.
