Concept explainers

Capacity and Level of Service at Intersections

The term capacity is associated with transportation engineering. Capacity helps to understand how many pedestrians or vehicles can be handled by a transport facility. Level of service is also a term associated with transportation engineering. The level of service indicates the performance of the transport facility.

The traffic from a suburban area to a city uses the following five shorter routes, as shown below. Access from Suburban Route 4 Route 1 Route 5 Route 2 Route 3 Access to City The models below show the travel time as a function of traffic flow on each route. t₁ = 18 + 4.5 x₁ t₂ = 21+ 7.0 x₂ t3 = 26 + 4.9 x3 t4 = 29+ 3.4 x4 t5 = 34 + 0.3 x5 Where: t; is travel time on route 'i' (in minutes) and x; is traffic flow on route 'i' (in 1000 vehicles).
The traffic demand for a six-lane urban arterial road (three lanes per direction) is given in the table below. The relationship between flow and density for this road follows GreenShiled's model, with a free flow speed of 105 km/h and a jam density of 92 veh/km/lane. Two of the three lanes of the EB direction were closed at 5:00 AM for maintenance. The two lanes were re-opened at 8:00 AM, allowing the traffic to be released at capacity conditions. a) What is the maximum length of the queue upstream of the bottleneck? b) At what time the queue upstream of the bottleneck will be fully dissipated? c) What is the furthest point upstream of the bottleneck that will be impacted by the lane closure? d) Draw the shock wave diagram showing shock wave speeds, critical times, and distances.

The average number of collisions on Rt. 116 in South Deerfield is 15 per year. To address the high crash rate, a signal has been installed to make right-of-way explicit. The number of accidents in the following year was 9. MassDOT desires to know with how much confidence this reduction of accidents can be attributed to anything other than random chance.
