Moving hazardous materials demands zero tolerance for routing errors. NextBillion.ai's Route Optimization API is engineered specifically for HAZMAT transport—enforcing regulatory restrictions, vehicle-dimension constraints, and restricted-zone avoidance across every route plan. Reduce compliance risk, cut operational costs, and dispatch HAZMAT-compliant routes in seconds, even across large multi-vehicle fleets.
End-to-end API capabilities purpose-built for safe, compliant, and cost-efficient hazardous materials transport operations.
Generate dispatch-ready routes that automatically enforce HAZMAT road restrictions, tunnel codes, bridge weight limits, and vehicle-class regulations—solving 50+ hard and soft constraints in seconds for single vehicles or entire fleets.
Compute precise, regulation-compliant routes for HAZMAT vehicles by specifying cargo type, vehicle dimensions, axle load, and weight class—avoiding restricted roads, low-clearance underpasses, and prohibited zones automatically.
Inject custom road rules—restricted corridors, no-entry zones, safe parking locations, and approved HAZMAT routes—directly into the routing engine without engineering effort, keeping every route calculation aligned with your operational reality.
Monitor HAZMAT vehicle locations in real time with sub-meter precision, receive instant alerts for route deviations or unauthorized movements, and maintain continuous visibility across your entire regulated fleet.
Rebuild complete, road-snapped trip records from GPS data to produce audit-ready compliance documentation—providing time-stamped, verifiable journey histories required for HAZMAT regulatory reporting and incident investigation.
Define restricted zones, approved depot boundaries, and HAZMAT exclusion areas as geofences—automatically rerouting vehicles around sensitive zones and triggering real-time alerts when assets approach or enter prohibited areas.
Submit your vehicle's dimensions—height, weight, axle load, length—and specify the HAZMAT cargo classification. The API uses these parameters to filter out every non-compliant road segment before route calculation begins, ensuring no prohibited corridor is ever included.

"By substantially reducing the number of developer hours spent on scheduling, NextBillion.ai's MVRP and large Distance Matrix API have helped us improve our operational efficiency and increase our cost savings significantly!"
"Support very good and friendly. Nextbillion provide the maps distance calculation with the low price but high value service to us. Nextbilions has help us reduce the cost and provide the same service as google!"
"Rich in features, light in the pocket. NextBillion.ai is solving the complex processes of the best route for the right vehicle."
"We were unhappy with the pricing from big players in this space and needed a scalable alternative that offered customizability. NextBillion.ai's Maptiles API was exactly what we were looking for. For companies in the ferry and nautical map domain, we'd highly recommend NextBillion.ai."
"I admire NextBillion.ai's fast response and friendly manners whenever we need professional support in geospatial data processing. They have delivered a valuable service and support to our company that we appreciate."

NextBillion.ai delivers the routing intelligence, compliance tooling, and pricing transparency that hazardous materials transport demands.
Vehicle dimension constraints, cargo classifications, and HAZMAT road restrictions are built into every route calculation—not bolted on as post-processing filters.
Model complex regulatory environments across federal, state, and municipal HAZMAT routing rules with 50+ configurable hard and soft constraints per request.
Automatically generate time-stamped, road-snapped trip documentation that satisfies HAZMAT compliance audit and regulatory reporting requirements.
Per-vehicle and per-order pricing prevents budget overruns during demand spikes and re-optimization cycles—no per-API-call penalties as routing frequency scales.
The founders and engineers who built enterprise-grade HAZMAT routing intelligence.
Co-Founder
Gaurav Bubna drives product innovation at NextBillion.ai, bringing deep expertise in building high-scale logistics and mobility products from the ground up. Before co-founding NextBillion.ai, Gaurav held senior product roles at Grab, Ola, and Morgan Stanley, where he shaped routing, dispatch, and location intelligence systems that moved millions of users and deliveries daily. His hands-on experience with the operational complexity of regulated transport—where a single routing error can mean a compliance violation or a safety incident—directly informs NextBillion.ai's approach to HAZMAT-compliant route optimization. Gaurav's work at Grab's Geo team, alongside co-founders Ajay Bulusu and Shaolin Zheng, laid the foundation for a platform built to handle the routing problems that matter most to operators moving sensitive cargo at scale.
The API accepts vehicle parameters including cargo classification, vehicle weight, axle load, height, and width. These inputs are matched against road-level restriction data—bridge weight limits, tunnel restriction codes, truck-prohibited streets, and HAZMAT exclusion zones—before route calculation, so every generated route is compliant by construction, not by post-processing review.
