A Closer Look: Local Area Transportation Review (LATR) for Montgomery County Maryland

In June, we presented a webinar about Travel Demand Management Plans (TDMPs) and our approach to these types of studies (view it and others here). A listener reached out to us afterward with a new plan from Montgomery County in Maryland. Their recently updated Local Area Transportation Review (LATR) Guidelines are intended for the preparation […]

School Speed Zones

By Bryant Ficek, PE, PTOE For a city traffic engineer, nothing signifies the end of summer quite like the barrage of calls from concerned parents (and sometimes school officials) requesting school speed zones and safety improvements. With so much at stake and so many factors to consider, school speed zones can easily become one of […]

Traffic Engineering Briefing: When is a road congested?

By Mike Spack, PE, PTOE A road feels congested to motorists when the traffic demand approaches the capacity of the roadway.  The two biggest factors that determine if a road feels congested are volume (how many vehicles are using the road) and capacity (how many vehicles the road can accommodate a day). Transportation professionals use […]

Do Crosswalk Bumpouts Really Enhance Pedestrian Safety?

I wrote this article several years ago but feel bumpouts are still a relevant and under analyzed area of traffic engineering. I still receive question from readers and clients about crosswalk bumpouts and their effectiveness and felt it was timely to share this article again. Have you seen an improvement in pedestrian safety through the […]

Access and Circulation at a Distribution Center

The equation for solving access-related issues seems to be a simple one: increase accessibility, reduce conflict points and voila! Problem solved, right? Not so fast. As any traffic engineer can attest to, identifying and implementing solutions to any traffic-related conflict – particularly those that impact accessibility – is seldom as cut and dry as one […]
