The Michigan Department of Transportation (MDOT) recently issued an RFP that includes some key performance indicators (KPI’s) for real-time traffic data. Moonshadow Live Traffic is a break-through in both speed and accuracy for real-time traffic data by using Wejo connected vehicle data from over 10 million vehicles in the US. has developed Moonshadow Live Traffic, powered by Wejo Ltd’s real-time connected vehicle data, to give traffic managers access to maps that show the traffic situation for any area in the US with a latency of 30 seconds or less. In comparing annual 2019 Mapbox segment volumes data with MDOT’s road utilization counts data within downtown and adjacent suburb areas (shown below), we found that, for 90% of road segments, the indexed vehicle activity calculated by Mapbox fell within 10% of indexed total vehicle activity counts published by MDOT.Moonshadow Mobile, Inc. Nonetheless, it is a valuable resource with which to compare and validate Mapbox Movement data. Segments are updated whenever new figures are created for a given segment, so not all segments are up to date. In fact, MDOT tracks and publishes the most recent segment count data they have available for most major roads in the state. Michigan Department of Transportation (MDOT) provides traffic counts data available to the public. One explanation for this pattern is that retail activities in the afternoon and evening have largely returned, while office commute-related peak hours have not. Instead, we see increased overall traffic throughout the day, with a late afternoon peak beginning to take form (but nothing close to the volume of peak traffic observed in 2019). Woodward Avenue in Detroit exhibited increased overall traffic volumes between Highland Park and Downtown, but the AM and PM peaks that were characteristic of the corridor in 2019 have not yet returned. Vehicle activity index for Woodward Avenue corridor by hour, on average, for the last week of March. This encompasses the urban core of Detroit and its western suburbs (roads within Canada were excluded). This period was selected to capture the effects of COVID in 2020 and compare that with the equivalent timeframe in both 20. We evaluated the 3-month period from mid-March to mid-June (Spring season) for the nine Z10 quadkey tiles shown below. Furthermore, Mapbox Movement data provides more fine-grained time-of-day insights and coverage on additional road classes. Mapbox Vehicle activity indices in more than 90% of road segments lie within 10% of the equivalent MDOT-produced statistics. To confirm the validity of our analysis, we compare our results to the official Michigan Department of Transportation (MDOT) vehicle counts data for the same area. We also look at some example drill-downs to compare traffic patterns between different years on specific roads by time of day. The granularity of our data allows us to determine, for example, that between 20 vehicle activity on highways around Detroit has decreased, while activity on residential roads went up. In this blog post, we explore road-segment-based vehicle activity index data to analyze traffic volumes in the Detroit metro area. Downtown Detroit road segment volumes, from red (lower) to blue (higher).
