Overview

The ultimate interstate travel companion

RoadNinja transformed the American road trip by putting real-time travel intelligence at drivers' fingertips. Built in partnership with Lamar Advertising — the largest outdoor advertising company in the United States — the app combined GPS-powered navigation with live gas prices, hotel booking, and targeted promotions to create a comprehensive interstate travel companion.

What began as a mobile app grew into a multi-platform ecosystem spanning iOS, Android, desktop web, and even connected car dashboards, earning the #1 spot in the Travel category and surpassing 1 million downloads.

The app featured promotions from major brands like McDonald's, Wendy's, Subway, Domino's Pizza, Community Coffee, Holiday Inn Express, and Hampton Inn — making it possible to deliver targeted promotions and engage customers on the interstate for the first time.

The Challenge

Bridging the gap between billboards and digital

Lamar Advertising needed a way to extend its physical billboard network into the digital world. Interstate travelers relied on fragmented sources for trip information, and there was no unified platform connecting drivers with the brands and services along their route.

Fragmented Travel Data

Interstate travelers relied on dozens of separate apps and websites for gas prices, hotel availability, restaurant reviews, and points of interest — with no unified source.

No Digital Bridge for Billboards

Lamar's 350,000+ billboard faces generated awareness but had no way to connect physical signage to digital engagement or measurable conversions.

Real-Time Pricing at Scale

Gas prices change hourly across 8,000+ cities. Aggregating, normalizing, and displaying accurate pricing required a sophisticated data pipeline.

Safe UX for Drivers

Building an app that drivers could safely use at highway speeds demanded a fundamentally different approach to information architecture and interaction design.

The Solution

A complete road trip platform

Digital Scientists designed and built a multi-platform ecosystem that organized every US interstate exit into a browsable, searchable index — complete with live gas prices, hotel booking, user reviews, and geo-targeted promotions from major national brands.

Key Features

Intelligence at every exit

Exit-by-exit navigation

RoadNinja organized every US interstate exit into a browsable, searchable index of points of interest. Drivers could see what's at each upcoming exit — gas stations, restaurants, hotels, attractions — without leaving the highway.

Custom-built interstate highway and exit data was aggregated and curated from several sources, combined with OPIS (Oil Price Information Service) for real-time fuel pricing across the country.

Live gas prices & hotel booking

Real-time gas price aggregation across 8,000+ cities helped drivers find the cheapest fuel along their route. Integrated hotel search and booking turned the app into a one-stop travel platform.

Drivers could compare prices at every upcoming exit, view guest ratings and amenities for hotels, and book rooms directly from the app — all without pulling over.

Targeted promotions

Major brands like Subway, McDonald's, and Shell could deliver geo-targeted offers to drivers as they approached relevant exits, creating a new digital advertising channel tied to Lamar's physical billboard network.

The ad platform supported dayparting for delivery of offers and promotions by nearby retailers and restaurants, bridging the gap between outdoor advertising and measurable digital engagement.

Admin Platforms

Managing content at scale

Behind the consumer-facing apps, Digital Scientists built two comprehensive admin platforms. The Promotions Admin gave advertisers tools to create, schedule, and geo-target promotional campaigns tied to specific exits and routes. The Reviews Admin provided content moderation, analytics, and quality management across thousands of user-generated reviews.

Connected Car

From phone to dashboard

In partnership with AT&T's Drive Studio, Digital Scientists adapted the RoadNinja experience for in-vehicle infotainment systems. The connected car prototype reimagined the app's core functionality — exit navigation, gas prices, and promotions — for the unique constraints of automotive displays, bringing the road trip companion directly into the car's dashboard.
