Plan last-mile delivery routes and stop density for a depot

Help me plan last-mile delivery routes for my depot. Depot and area: [DEPOT LOCATION, AREA SERVED, URBAN / SUBURBAN / RURAL MIX] Daily volume: [AVERAGE AND PEAK STOPS AND PACKAGES PER DAY, BY ZIP OR ZONE IF KNOWN] Stop types: [residential, business, apartments, lockers, signature required, large items] Time windows and cutoffs: [e.g. "business stops before noon", "all routes out by 9:00", "back by 19:00"] Vehicles: [TYPE, CAPACITY IN PACKAGES OR CUBE, NUMBER AVAILABLE] Driver rules: [shift length, breaks, hours limits, pay model] Current performance: [stops per hour, stops per route, failed deliveries, on-time %, miles per route] Routing tool: [routing software name or "manual"] Work through: 1. Zoning: split the area into routes balanced by workload (stops and drive time), not just by stop count. 2. Number of routes needed on a normal day and at peak, with a buffer. 3. Load sequence for vans so the first stops are loaded last. 4. Rules for failed deliveries, redeliveries, and when to reroute. 5. How to handle peak: flex drivers, extra waves, pickup points. 6. KPIs: stops per hour, cost per stop, first-attempt success rate, on-time rate. Return: a route plan table (Route | Zones | Expected stops | Drive time | Service time | Vehicle), a morning dispatch checklist, and 5 ways to raise stops per hour without pushing drivers to cut safety corners. Use only my numbers; flag assumptions as [ASSUMPTION]. Keep plans within driver hours and break rules for my location.
