One entry straight, a transition curve (spiral) and a circular curve, a symmetrical spiral and a final straight geometrically compose the considered road. The dispersion of the trajectories for different speeds and lengths of the spirals and different radius of the circular curve has been analyzed. The outcomes show that usually assumed approaches in road geometry design can sometimes induce a deficit of safety. For example, when the angular deviation of the circular curve is greater than 40°, the safety standard decreases if the spiral length increases. This result seems to disappoint the well-established know-how. It cannot be explained through physical relationships, because of it refers to human perception and reaction. Secondly the paper presents more advanced results, that have been obtained using an interactive driving simulator. A road, in closed path configuration, is designed for simulation. A complete simulation survey has been carried out, recording the trajectories, the speeds, the accelerations, some bio-medical parameters, and more than 30 other parameters. This experimental survey greatly confirms the effectiveness of the simulation approach to validate the standards of the road geometry, for the safety assessment. Finally, the study, sometimes contrary to the usual traditionally adopted technical rules, demonstrates it is not possible to set a geometrical safe standard, unless the impact on the human factors is verified.]]> Wed, 15 Nov 2023 09:19:57 GMT https://trid.trb.org/View/2148760 Multilevel Analysis of Road Accident Frequency: The Impact of the Road Category https://trid.trb.org/View/2247547 Thu, 12 Oct 2023 09:36:03 GMT https://trid.trb.org/View/2247547 Investigating the Effect of Layer Thickness on the Variability of Porous Asphalt Tyre/Road Noise https://trid.trb.org/View/2240274 Tue, 10 Oct 2023 11:40:00 GMT https://trid.trb.org/View/2240274 What causes slow-down on two-way two-lane expressways? https://trid.trb.org/View/2259795 Mon, 02 Oct 2023 11:29:57 GMT https://trid.trb.org/View/2259795 Traffic Congestion Assessment Tool for Urban Roads Based on Traffic and Geometric Characteristics: A Case of Hyderabad, India https://trid.trb.org/View/2237524 Mon, 02 Oct 2023 09:14:01 GMT https://trid.trb.org/View/2237524 Estimating Roadway Horizontal Alignment from Geographic Information Systems Data: An Artificial Neural Network–Based Approach https://trid.trb.org/View/2227697 Wed, 13 Sep 2023 10:23:11 GMT https://trid.trb.org/View/2227697 Impacts of autonomous vehicles on road and pavement design https://trid.trb.org/View/2239964 Wed, 06 Sep 2023 14:05:32 GMT https://trid.trb.org/View/2239964
