Bank Bench

A simulation and benchmarking tool that lets facility engineers A/B-test elevator dispatch algorithms (LOOK, RSR, destination dispatch) against their own building's traffic profile before committing to an upgrade.

Target user

facility engineers and property managers planning an elevator modernization

Features
  • Drag-and-drop building layout editor with floor, car, and lobby configurations
  • Traffic profile presets for office, residential, and hospital patterns plus custom imports
  • Side-by-side wait-time and journey-time histograms for each algorithm
  • Exportable spec sheet vendors will accept in an RFP
Why now

The HN-viral article makes the counterintuitive case that fancy destination dispatch is often worse than simple LOOK; engineers now have a stronger reason to question vendor upsells.

Demand
5/10

Multiple established traffic analysis tools (Elevate, AdSimulo, Liftaro, Simulations4All) confirm a real buyer pool, but facility engineers planning a one-off modernization is a narrow niche within the $20B+ modernization market.Elevate Traffic Analysis & Simulation — Peters ResearchLiftaro — Elevator Analytics & Design Tools

Whitespace
4/10

Space is already well-served by Peters Research Elevate (the entrenched commercial standard), AdSimulo, Liftaro, Lift-Traffic.com, free Simulations4All, and browser-based Elevat0r.com — far from a wide-open market.Elevat0r — Dynamic Elevator System SimulatorAdSimulo | Lift Traffic Analysis & Simulation ApplicationFree Elevator Traffic Analysis Calculator | Simulations4All

Monetization
5/10

Peters Research has sustained a paid product for years selling to consultants, proving willingness to pay; however, free tools (Simulations4All, Elevat0r) and competing SaaS (AdSimulo, Liftaro) compress pricing for the narrower 'A/B test before upgrade' use case.Elevate Traffic Analysis & Simulation — Peters ResearchFree Elevator Traffic Analysis Calculator | Simulations4All

Longevity
7/10

Elevator modernization is a long-cycle, growing industry projected at 5–7% CAGR to $20–39B by 2030, and skepticism of vendor destination-dispatch upsells (per the HN article) gives the tool durable relevance.Elevator Modernization Market Size, Growth Analysis 2026Destination dispatch - Wikipedia

Feasibility
6/10

Open-source simulators (SimElevatorTraffic, Elevat0r) plus well-documented algorithms (LOOK, RSR, destination dispatch) make a web-based A/B benchmarking tool buildable, though accurate ingestion of real building traffic profiles adds complexity.GitHub - charles-works/SimElevatorTraffic: Professional elevator traffic simulationSimple Elevator Simulator - Interactive Algorithm Visualization
